This repository bundles convenience Makefiles for developing software targeting the embedded processors of SoC FPGAs or soft cores embedded in a programmable logic (PL) design – so called Processing Systems (PS). It features the following components:

PetaLinux wrapper Makefile
Xilinx Software Development Kit (XSDK) convenience Makefile
Xilinx Vitis convenience Makefile

PetaLinux Wrapper Makefile

petalinux.mk is a Makefile for PetaLinux projects. It acts as convenience wrapper script around the PetaLinux toolchain and adds additional functionality.

Supported Platforms

PetaLinux is supported from v2018.1 to v2019.1 (i.e. the last four releases). The Makefile should run on all underlying OSs supported by PetaLinux; however testing is only conducted on Ubuntu 18.04 LTS (Bionic Beaver) as of now.

Setup

In your PetaLinux project directory, create a symlink named Makefile to the petalinux.mk file:

$ ln -s <path-to-your-psmake-repo>/petalinux.mk Makefile

Then, execute:

$ make HDF=<path-to-your-.hdf-or-.xsa-file>

to import a Hardware Description File (HDF) or a XSA file and build the PetaLinux project.

Usage

The following Makefile targets are provided:

gethdf: Initialize the project with a Hardware Description File (HDF) or a XSA file. You must provide a HDF or XSA file via the HDF variable.
config: Configure system-level options.
config-kernel: Configure the Linux kernel.
config-rootfs: Configure the root filesystem.
build (default): Build the system.
sdk: Build the Software Development Kit (SDK).
package-boot: Package boot image. You can provide different binaries from the default ones for bitstream, FSBL, ATF, PMU firmware and U-Boot via the BIT, FSBL, ATF, PMUFW and UBOOT variables, respectively. To skip packaging bitstream, FSBL, ATF or PMU firmware, set the respective variable to no. Additional boot arguments can be specified with BOOT_ARG_EXTRA; run petalinux-package --boot --help for a list of options. The output path can be changed with the BOOT variable.
package-prebuilt: Copy built artifacts to pre-built directory.
package-bsp: Package Board Support Package (BSP). The BSP file name must be given with the BSP variable.
dts: Decompile the device tree.
reset-jtag: Reset board via JTAG. The hardware server URL must be provided via the HW_SERVER_URL variable.
boot-jtag-u-boot: Boot board into U-Boot via JTAG. The hardware server URL must be provided via the HW_SERVER_URL variable.
boot-jtag-kernel: Boot board and upload Linux kernel via JTAG. The hardware server URL must be provided via the HW_SERVER_URL variable.
boot-jtag-psinit-uboot: Boot board into U-Boot via JTAG, but run ps*_init.tcl script instead of downloading and running FSBL. This can be inconvenient if the FSBL is doing boot mode specific jobs, e.g. loading a boot image from QSPI flash memory when in QSPI boot mode, although one does NOT want the FSBL to do that. The hardware server URL must be provided via the HW_SERVER_URL variable. Only available on Zynq-7000 as of now.
boot-qemu: Boot into QEMU.
flash-boot: Flash boot image onto board via JTAG. The hardware server URL must be provided via the HW_SERVER_URL variable. The flash type must be specified with the FLASH_TYPE variable if it deviates from the default. The FSBL used for flashing, the boot image and the flash offset can be changed with the FSBL_ELF, BOOT_BIN and BOOT_BIN_OFF variables respectively.
flash-kernel: Flash kernel image onto board via JTAG. The hardware server URL must be provided via the HW_SERVER_URL variable. The flash type must be specified with the FLASH_TYPE variable if it deviates from the default. The FSBL used for flashing, the kernel image and the flash offset can be changed with the FSBL_ELF, KERNEL_IMG and KERNEL_IMG_OFF variables respectively.
flash: Flash boot and kernel image onto board via JTAG.
mrproper: Clean all build artifacts. If this target is invoked with CLEAN_HDF=1, the HDF is deleted as well (i.e. all files in folder project-spec/hw-description except file metadata).

Networkless Builds

In some circumstances, it might be desirable to perform builds without any network access; notably,

to provide long-term reproducibility in case of package sources being not available online anymore.
to perform builds in corporate environments with restricted internet access.

Setup

A number of PetaLinux configuration options have to be changed to enable networkless builds; run make config and,

in Yocto Settings -> Add pre-mirror url, set the pre-mirror url path to your local source mirror, e.g file://${PROOT}/source-mirror (or set CONFIG_PRE_MIRROR_URL in project-spec/configs/config).
in Yocto Settings, uncheck Enable Network sstate feeds (or unset CONFIG_YOCTO_NETWORK_SSTATE_FEEDS in project-spec/configs/config).
in Yocto Settings, check Enable BB NO NETWORK (or set CONFIG_YOCTO_BB_NO_NETWORK in project-spec/configs/config).

Usage

All sources that are not part of the PetaLinux installation will be stored in the local source mirror. To update the source mirror, run:

$ make UPDATE_MIRROR=1

The local source mirror must be updated each and every time a package is added to the image. Notably, sources are only added to the source mirror, but never removed; so multiple revisions or entirely different PetaLinux projects can share a mirror. Cleanup of the source mirror should be performed manually when required.

Image Buildinfo

Add the following snippet to project-spec/meta-user/conf/petalinuxbsp.conf in order to write build information to the target filesystem on /etc/build:

INHERIT += "image-buildinfo"
IMAGE_BUILDINFO_VARS_append = " DATETIME"

/etc/build contains the build configuration as defined by the list of BitBake variables in IMAGE_BUILINFO_VARS and the Git revisions (branch/tag, commit ID and dirty flag) of all Yocto layers.

Appending variables to IMAGE_BUILDINFO_VARS is optional; however the build time DATETIME is recommended. A list of common variables can be found in the Variables Glossary of the Yocto Reference Manual.

Image Version

It is recommended to add image versioning information via os-release using the IMAGE_ID and IMAGE_VERSION variables.

Add the os-release package to your root filesystem and extend it via project-spec/meta-user/recipes-core/os-release/os-release.bbappend. The following example will add the variables BUILD_ID (build timestamp), IMAGE_ID and IMAGE_VERSION to /etc/os-release on the target filesystem, identifying the image as mle-example and reading the semantic version from version.txt in the PetaLinux root directory.

OS_RELEASE_FIELDS += "BUILD_ID IMAGE_ID IMAGE_VERSION"

IMAGE_ID = "mle-example"

python do_compile_prepend () {
    with open(d.getVar("TOPDIR") + "/../version.txt") as f:
        major, minor, patch = f.readline().rstrip().split(".")

    d.setVar("MAJOR_VERSION", major)
    d.setVar("MINOR_VERSION", minor)
    d.setVar("PATCH_VERSION", patch)
    d.setVar("IMAGE_VERSION", "{}.{}.{}".format(major, minor, patch))
}

Open Source License Compliance

There are three main areas of concern for open source license compliance.

Source code must be provided.
License text for the software must be provided.
Compilation scripts and modifications to the source code must be provided.

The first two points can be adressed by running:

$ make source-release SOURCE_RELEASE=<source-release-dir> MANIFESTS=<manifests-dir>

This will create tarballs for packages that require the release of source code (i.e. GPL) in the directory SOURCE_RELEASE (defaulting to source-release).

In addition, a license manifest is stored in directory MANIFESTS (defaulting to manifests) to assist with audits.

Some licenses require the license text to accompany the binary. You can achieve this by adding the following to your project-spec/meta-user/conf/petalinuxbsp.conf file:

COPY_LIC_MANIFEST = "1"
COPY_LIC_DIRS = "1"
LICENSE_CREATE_PACKAGE = "1"

Extending

If you need additional functionality in your project, put it into a file named local.mk.

XSDK Makefile

The XSDK Makefile provides a declarative wrapper around the Xilinx Software Command-Line Tool (XSCT) and Bootgen to streamline the build of Xilinx Software Development Kit (XSDK) projects.

Supported Platforms

XSDK is supported from v2018.1 to v2019.1 (i.e. the last four releases). The Makefile should run on all underlying Linux OSs supported by XSDK, but not Windows. However, testing is only conducted on Ubuntu 18.04 LTS (Bionic Beaver) as of now.

Build Configuration Syntax

The XSDK Makefile is configured via a custom syntax as documented in the following sections.

Hardware Platform Specification

The Hardware Platform Specification captures all the information from a hardware design that is required to write, debug and deploy software applications for that hardware. In the XSDK Makefile, there is exactly one hardware platform specification called hw by default ¹. The hardware platform specification is derived from the Hardware Description File (HDF) imported during build (see section Usage) and does not need to be configured.

Repositories

Board Support Packages

A Board Support Package (BSP) is a collection of libraries and drivers that form the basis of software applications (see section "Applications").

BSPs are registered by adding their name to the BSP_PRJS list. They can then be configured by prefixing the corresponding option with their name:

BSP_PRJS += fsbl_bsp
fsbl_bsp_PROC = psu_cortexa53_0
fsbl_bsp_IS_FSBL = yes
fsbl_bsp_LIBS = xilffs xilsecure xilpm
fsbl_bsp_POST_CREATE_TCL = configbsp -bsp fsbl_bsp use_strfunc 1

BSP_PRJS += gen_bsp
gen_bsp_PROC = psu_cortexa53_0
gen_bsp_STDOUT = psu_uart_1

The following BSP options are available:

OS: Operating system type. Optional, defaults to standalone. Run repo -os in XSCT to get a list of all OSs.
PROC: Processor instance. Run toolchain in XSCT to get a list of supported processor types.
ARCH: Processor architecture. Can be 32 or 64 bit. Valid only for processors supporting multiple architectures (e.g. A53).
PATCH: List of space-separated patch file entries. Patches are applied in the base directory of the respective BSP project. A patch file list entry has the format <patchfile>[;stripnum], where stripnum is the optional number of leading slashes to be stripped from each file name found in the patch file (default is 1).
SED: List of space-separated file entries to be transformed with sed (stream editor). Sed is run in the base directory of the respective BSP project. A sed list entry has the format <srcfile>;<sedfile>, where <srcfile> is the file to be transformed and <sedfile> the sed script file.
IS_FSBL: If yes, apply non-default BSP settings for FSBL.
EXTRA_CFLAGS: Additional compiler flags (default -g -Wall -Wextra). The default optimization level of -O2 can be overriden with this variable.
STDIN: Select UART for standard input.
STDOUT: Select UART for standard output.
LIBS: List of libraries to be added to the BSP. Run repo -lib in XSCT to get a list of available libraries.
POST_CREATE_TCL: Hook for adding extra Tcl commands after the BSP has been created. Can be used to configure BSP settings (via the configbsp command) not available in the XSDK Makefile.

Applications

Software application projects are your final application containers. They can either be derived from a template or contain your own source files. Each application project must be linked to exactly one BSP.

Application projects are registered by adding their name to the APP_PRJS list. They can then be configured by prefixing the corresponding option with their name:

APP_PRJS += fsbl
fsbl_TMPL = Zynq MP FSBL
fsbl_BSP = fsbl_bsp
fsbl_CPPSYMS = FSBL_DEBUG_DETAILED

APP_PRJS += helloworld
helloworld_TMPL = Hello World
helloworld_BSP = gen_bsp
helloworld_BCFG = Debug
helloworld_PATCH = helloworld.patch
helloworld_SED = platform.c;baud_rate.sed
helloworld_LIBS = helloworldlib

The following application project options are available:

TMPL: Name of the template to base the application project on. Run repo -apps in XSCT to get a list of available application templates.
PROC: Processor instance. Run toolchain in XSCT to get a list of supported processor types.
LANG: Programming language. Can be either c (default) or c++.
BSP: Reference to BSP. Required.
SRC: List of space-separated source files to be added to the application. For each list entry, a symlink in the src directory of the respective application project will be created that points towards the corresponding source file.
PATCH: List of space-separated patch file entries. Patches are applied in the src directory of the respective application project. A patch file list entry has the format <patchfile>[;stripnum], where stripnum is the optional number of leading slashes to be stripped from each file name found in the patch file (default is 1).
SED: List of space-separated file entries to be transformed with sed (stream editor). Sed is run in the src directory of the respective application project. A sed list entry has the format <srcfile>;<sedfile>, where <srcfile> is the file to be transformed and <sedfile> the sed script file.
BCFG: Build configuration. Can either be Release (default) or Debug.
OPT: Compiler optimization level. Can either be None (-O0), Optimize (-O1), Optimize more (-O2) (default), Optimize most (-O3), Optimize for size (-Os).
CPPSYMS: List of preprocessor symbols (e.g. MYSYMBOL=1).
LIBS: List of library projects the application depends on. The libraries are added to the include and library search paths and linked against the application.
POST_CREATE_TCL: Hook for adding extra Tcl commands after the application project has been created. Can be used to set application project configuration parameters (via the configapp command) not available in the XSDK Makefile.

Libraries

Software library projects are collections of commonly used functions for your applications. Library projects are independent of the hardware platform specification.

Library projects are registered by adding their name to the LIB_PRJS list. They can then be configured by prefixing the corresponding option with their name:

LIB_PRJS += helloworldlib
helloworldlib_PROC = psu_cortexa53
helloworldlib_BCFG = Debug
helloworldlib_SRC = helloworldlib.c libhelloworld.h

The following library project options are available:

TYPE: Library type. Can be either static (default) or shared. Type shared can only be used in combination with operating system type linux.
PROC: Processor type. Can be either ps7_cortex9, microblaze, psu_cortexa53 or psu_cortexr5. Required.
OS: Operating system type. Can be either standalone (default) or linux. Type linux can only be used in combination with library type shared.
LANG: Programming language. Can be either c (default) or c++.
ARCH: Processor architecture. Can be 32 or 64 bit. Valid only for processors supporting multiple architectures (e.g. A53).
SRC: List of space-separated source files to be added to the library. For each list entry, a symlink in the src directory of the respective library project will be created that points towards the corresponding source file.
BCFG: Build configuration. Can either be Release (default) or Debug.
OPT: Compiler optimization level. Can either be None (-O0), Optimize (-O1), Optimize more (-O2) (default), Optimize most (-O3), Optimize for size (-Os).
CPPSYMS: List of preprocessor symbols (e.g. MYSYMBOL=1).
POST_CREATE_TCL: Hook for adding extra Tcl commands after the library project has been created. Can be used to set library project configuration parameters (via the configapp command) not available in the XSDK Makefile.

Since XSDK does not support building Linux apps, the combination of library type shared and operating system type linux is not officially supported by the XSDK Makefile.

Bootgen

Bootgen is a Xilinx tool that merges build artifacts into a boot image according to a Boot Image Format (BIF) file. The XSDK Makefile can generate BIF files and invoke Bootgen subsequently.

Bootgen projects are registered by adding their name to the BOOTGEN_PRJS list. They can then be configured by prefixing the corresponding option with their name:

BOOTGEN_PRJS += bootbin
bootbin_BIF_ARCH = zynqmp

The following Bootgen project options are available:

BIF_ARCH: Device architecture. Run bootgen and see description of -arch option for a list of supported architectures.
BIF_ARGS_EXTRA: Add additional Bootgen arguments for special operations like key generation.
NO_OUTPUT: If yes', do not write a boot image file. Required for certain operations like key generation.
FLASH_TYPE: Flash memory type. Run program_flash and see description of option -flash_type to get a list of supported memory types. Only needed for flash target (see section "Usage").
FLASH_FSBL: FSBL used for flashing. Only needed for flash target (see section "Usage").
FLASH_OFF: Offset within the flash memory at which the image should be written. Only needed for flash target (see section "Usage").

BIF attributes are then registered by adding their name to the BIF_ATTRS list. They can then be configured by prefixing the BIF_ATTR and BIF_FILE variables with the Bootgen project name and BIF attribute name:

bootbin_BIF_ATTRS = fsbl helloworld
bootbin_fsbl_BIF_ATTR = bootloader, destination_cpu=a53-0
bootbin_fsbl_BIF_FILE = fsbl/$(fsbl_BCFG)/fsbl.elf
bootbin_helloworld_BIF_ATTR = destination_cpu=a53-0
bootbin_helloworld_BIF_FILE = helloworld/$(helloworld_BCFG)/helloworld.elf

This example is translated to the following BIF file:

bootbin:
{
    [bootloader, destination_cpu=a53-0] fsbl/Release/fsbl.elf
    [destination_cpu=a53-0] helloworld/Debug/helloworld.elf
}

Prerequisites to all BIF_FILEs are added to the corresponding BIF generation rules. If, however, the concerning file is created instead of consumed by Bootgen (e.g. key generation) or is not a file at all, one must set the BIF_FILE_NO_DEP variable to yes. For example:

...
generate_pem_BIF_ARGS_EXTRA = -p zu9eg -generate_keys pem
...
generate_pem_pskfile_BIF_ATTR = pskfile
generate_pem_pskfile_BIF_FILE = generate_pem/psk0.pem
generate_pem_pskfile_BIF_FILE_NO_DEP = yes
...

The file name of a bitstream depends on the Vivado design and is often not known before the HDF has been extracted. In these cases, by convention, one should point the corresponding BIF_FILE option to a variable named like BIT:

bootbin_bit_BIF_ATTR = destination_device=pl
bootbin_bit_BIF_FILE = $(BIT)

The BIT variable must then be provided on invocation:

$ make HDF=<path-to-your-hdf> BIT=hw/<bitstream>.bit

Optionally, one can provide a default as well:

BIT ?= hw/design_1_wrapper.bit

Setup

Create a symlink named Makefile to the xsdk.mk file:

$ ln -s <path-to-your-psmake-repo>/xsdk.mk Makefile

Add the build directory to your .gitignore.

By default, the XSDK Makefile looks for the build configuration in ./default.mk. If you choose a different file name (or like to have multiple build configurations), you can specify the path with the CFG variable.

Write your build configuration as documented in section "Makefile syntax". Instead of writing the build configuration from scratch, you can also copy templates/default.mk into your working directory.

Usage

Import a HDF and build all projects by executing:

$ make HDF=<path-to-your-hdf>

The XSDK Makefile creates a new XSDK workspace as a subfolder in directory build named <cfg-file-name>_<date>-<time>_<git-commit-id>. A new XSDK workspace is created on each invocation. If you would like to run the XSDK Makefile on a specific workspace instead of creating a new one, you can use the O variable:

$ make O=build/<cfg-file-name>_<date>-<time>_<git-commit-id>

The XSDK Makefile dynamically creates targets according to the build configuration. Each BSP, application project and Bootgen project is assigned a build target with the same name. Additionally each BSP and application project feature a clean and distclean target separated by _. In order to e.g. clean the application project helloworld, one would execute:

$ make helloworld_clean

Bootgen projects come with a flash target to write the boot image onto a board via JTAG. In order to e.g. flash the Bootgen project bootbin, one would execute:

$ make bootbin_flash HW_SERVER_URL=<hw-server-url>

In addition, the following generic Makefile targets are available:

hw: Build the hardware platform specification. You must provide a HDF via the HDF variable.
hw_distclean: Clean the hardware platform specification.
generate: Generate all projects.
build (default): Build all projects.
metalog: Show meta log.
sdklog: Show XSDK log.
xsdk: Run XSDK.
xsct: Run XSCT.
clean: Clean all projects.
distclean: Remove workspace.

Extending

The build configuration file can be extended with standard Makefile targets for e.g. uploading and running build artifacts via JTAG.

Vitis Makefile

The Vitis Makefile provides a declarative wrapper around the Xilinx Software Command-Line Tool (XSCT) and Bootgen to streamline the build of Xilinx Vitis projects.

Supported Platforms

Vitis is supported in v2020.1. So far, there is a focus on the previous XSDK use cases; while SDAccel/SDSoC use cases might work as well, they are not supported yet. The Makefile should run on all underlying Linux OSs supported by Vitis, but not Windows. However, testing is only conducted on Ubuntu 18.04 LTS (Bionic Beaver) as of now.

Known Issues

Due to a bug in the Vitis Tcl API, when building an application the corresponding domain is always rebuild as well. It is therefore recommended to build applications in the Vitis GUI once the workspace has been created.

Build Configuration Syntax

The Vitis Makefile is configured via a custom Makefile syntax as documented in the following sections.

Repositories

A software repository is a directory that holds third-party software components, as well as custom drivers, libraries, and operating systems. You can register repositories in the workspace by adding the respective path to the REPOS variable. In addition, you can also register existing platforms by adding the respective path to the PLATS variable.

Platform

The Platform captures all the information from a hardware design that is required to write, debug and deploy applications for that hardware. In the Vitis Makefile, there is exactly one platform called plat by default ¹. The platform is either derived from

a hardware description file (XSA)
an existing platform via the corresponding XPFM file.

See section "Usage" on how to import one of these artifacts during build.

Domains (BSP)

A Domain or Board Support Package (BSP) is a collection of libraries and drivers that form the basis of software applications (see section "Applications"). There can be only one domain for each processor instance (i.e. core).

Domains are registered by adding their name to the DOMAIN_PRJS list. They can then be configured by prefixing the corresponding option with their name:

DOMAIN_PRJS += fsbl_bsp
fsbl_bsp_PROC = psu_cortexa53_0
fsbl_bsp_IS_FSBL = yes
fsbl_bsp_LIBS = xilffs xilsecure xilpm
fsbl_bsp_POST_CREATE_TCL = configbsp -bsp fsbl_bsp use_strfunc 1

DOMAIN_PRJS += gen_bsp
gen_bsp_PROC = psu_cortexa53_0
gen_bsp_EXTRA_CFLAGS = -g -Wall -Wextra -Os
gen_bsp_STDOUT = psu_uart_1

The following domain options are available:

OS: Operating system type. Optional, defaults to standalone. Run repo -os in XSCT to get a list of all OSs.
PROC: Processor instance. Run toolchain in XSCT to get a list of supported processor types.
IS_FSBL: If yes, apply non-default BSP settings for FSBL.
EXTRA_CFLAGS: Additional compiler flags (default -g -Wall -Wextra). The default optimization level of -O2 can be overriden with this variable.
STDIN: Select UART for standard input.
STDOUT: Select UART for standard output.
LIBS: List of libraries to be added to the domain. Run repo -lib in XSCT to get a list of available libraries.
POST_CREATE_TCL: Hook for adding extra Tcl commands after the domain has been created. Can be used to configure BSP settings (via the configbsp command) not available in the Vitis Makefile.

Applications

Application projects are your final application containers. They can either be derived from a template or contain your own source files. Each application project must be linked to exactly one Domain (BSP).

Application projects are registered by adding their name to the APP_PRJS list. They can then be configured by prefixing the corresponding option with their name:

APP_PRJS += fsbl
fsbl_TMPL = Zynq MP FSBL
fsbl_DOMAIN = fsbl_bsp
fsbl_CPPSYMS = FSBL_DEBUG_DETAILED

APP_PRJS += helloworld
helloworld_TMPL = Hello World
helloworld_DOMAIN = gen_bsp
helloworld_BCFG = Debug
helloworld_PATCH = helloworld.patch
helloworld_SED = platform.c;baud_rate.sed

The following application project options are available:

TMPL: Name of the template to base the application project on. Run repo -apps in XSCT to get a list of available application templates.
PROC: Processor instance. Run toolchain in XSCT to get a list of supported processor types.
DOMAIN: Reference to domain (BSP). Required.
PLAT: Reference to platform. Use this to base the application on a different platform than the default plat. The platform must be available in the platform repository; see section "Repositories". Mutually exclusive with HW option.
HW: Path to hardware definition file (XSA) or platform file (XPFM). Use this to base the application on a hardware platform file instead of the plat platform. Mutually exclusive with PLAT.
SRC: List of space-separated source files or directories to be added to the application. For each list entry, a link entry in the application project to the absolute path of the respective source file or directory is created.
PATCH: List of space-separated patch file entries. Patches are applied in the base directory of the respective application project. A patch file list entry has the format <patchfile>[;stripnum], where stripnum is the optional number of leading slashes to be stripped from each file name found in the patch file (default is 1).
SED: List of space-separated file entries to be transformed with sed (stream editor). Sed is run in the base directory of the respective application project. A sed list entry has the format <srcfile>;<sedfile>, where <srcfile> is the file to be transformed and <sedfile> the sed script file.
BCFG: Build configuration. Can either be Release (default) or Debug.
OPT: Compiler optimization level. Can either be None (-O0), Optimize (-O1), Optimize more (-O2) (default), Optimize most (-O3), Optimize for size (-Os).
CPPSYMS: List of preprocessor symbols (e.g. MYSYMBOL=1).
POST_CREATE_TCL: Hook for adding extra Tcl commands after the application project has been created. Can be used to set application project configuration parameters (via the configapp command) not available in the Vitis Makefile.

Bootgen

Bootgen is a Xilinx tool that merges build artifacts into a boot image according to a Boot Image Format (BIF) file. The Vitis Makefile can generate BIF files and invoke Bootgen subsequently.

Bootgen projects are registered by adding their name to the BOOTGEN_PRJS list. They can then be configured by prefixing the corresponding option with their name:

BOOTGEN_PRJS += bootbin
bootbin_BIF_ARCH = zynqmp

The following Bootgen project options are available:

BIF_ARCH: Device architecture. Run bootgen and see description of -arch option for a list of supported architectures.
BIF_ARGS_EXTRA: Add additional Bootgen arguments for special operations like key generation.
NO_OUTPUT: If yes', do not write a boot image file. Required for certain operations like key generation.
FLASH_TYPE: Flash memory type. Run program_flash and see description of option -flash_type to get a list of supported memory types. Only needed for flash target (see section "Usage").
FLASH_FSBL: FSBL used for flashing. Only needed for flash target (see section "Usage").
FLASH_OFF: Offset within the flash memory at which the image should be written. Only needed for flash target (see section "Usage").

bootbin_BIF_ATTRS = fsbl helloworld
bootbin_fsbl_BIF_ATTR = bootloader, destination_cpu=a53-0
bootbin_fsbl_BIF_FILE = fsbl/$(fsbl_BCFG)/fsbl.elf
bootbin_helloworld_BIF_ATTR = destination_cpu=a53-0
bootbin_helloworld_BIF_FILE = helloworld/$(helloworld_BCFG)/helloworld.elf

This example is translated to the following BIF file:

bootbin:
{
    [bootloader, destination_cpu=a53-0] fsbl/Release/fsbl.elf
    [destination_cpu=a53-0] helloworld/Debug/helloworld.elf
}

...
generate_pem_BIF_ARGS_EXTRA = -p zu9eg -generate_keys pem
...
generate_pem_pskfile_BIF_ATTR = pskfile
generate_pem_pskfile_BIF_FILE = generate_pem/psk0.pem
generate_pem_pskfile_BIF_FILE_NO_DEP = yes
...

bootbin_bit_BIF_ATTR = destination_device=pl
bootbin_bit_BIF_FILE = $(BIT)

The BIT variable must then be provided on invocation:

$ make HDF=<path-to-your-hdf> BIT=hw/<bitstream>.bit

Optionally, one can provide a default as well:

BIT ?= hw/design_1_wrapper.bit

Setup

Create a symlink named Makefile to the vitis.mk file:

$ ln -s <path-to-your-psmake-repo>/vitis.mk Makefile

Add the build directory to your .gitignore.

By default, the Vitis Makefile looks for the build configuration in ./default.mk. If you choose a different file name (or like to have multiple build configurations), you can specify the path with the CFG variable.

Write your build configuration as documented in section "Makefile syntax". Instead of writing the build configuration from scratch, you can also copy templates/vitis/default.mk into your working directory.

Usage

Import either a hardware description file (XSA) by executing

$ make HDF=<path-to-.xsa-file>

or an existing platform via an XPFM file:

$ make XPFM=<path-to-.xpfm-file>

Without specyfing a further target, all projects will be built.

The Vitis Makefile creates a new Vitis workspace as a subfolder in directory build named <cfg-file-name>_<date>-<time>_<git-commit-id>. A new Vitis workspace is created on each invocation. If you would like to run the Vitis Makefile on a specific workspace instead of creating a new one, you can use the O variable:

$ make O=build/<cfg-file-name>_<date>-<time>_<git-commit-id>

The Vitis Makefile dynamically creates Makefile targets according to the build configuration. Each domain, application project and Bootgen project is assigned a build target with the same name. Additionally each domain and application project feature a clean and distclean target separated by _. In order to e.g. clean the application project helloworld, one would execute:

$ make helloworld_clean

Bootgen projects come with a flash target to write the boot image onto a board via JTAG. In order to e.g. flash the Bootgen project bootbin, one would execute:

$ make bootbin_flash HW_SERVER_URL=<hw-server-url>

In addition, the following generic Makefile targets are available:

plat: Build the platform project. Either provide a path to a hardware description file (XSA) via the HDF variable, or to an existing platform file (XPFM) via the XPFM variable.
plat_distclean: Clean the platform project.
generate: Generate all projects.
build (default): Build all projects.
metalog: Show meta log.
vitislog: Show Vitis log.
vitis: Run Vitis.
xsct: Run XSCT.
clean: Clean all projects.
