|

; * @file startup_stm32f4xx.s for ThreadX; IAR ARM assembler
|
||||
; * @brief CMSIS Cortex-M4F Core Device Startup File for STM32F40xx devices
|
||||
; * @version CMSIS 4.3.0
|
||||
; * @date 20 August 2015
|
||||
; *
|
||||
; * @description
|
||||
; * Created from the CMSIS template for the specified device
|
||||
; * Quantum Leaps, www.state-machine.com
|
||||
; *
|
||||
; * @attention
|
||||
; * Adapted for ThreadX STM32demo library, which is NOT CMSIS-compiliant.
|
||||
; * Specifically, the standard Cortex-M exception names required by
|
||||
; * ThreadX are different than prescribed by CMSIS.
|
||||
; *
|
||||
; * @note
|
||||
; * The function assert_failed defined at the end of this file defines
|
||||
; * the error/assertion handling policy for the application and might
|
||||
; * need to be customized for each project. This function is defined in
|
||||
; * assembly to re-set the stack pointer, in case it is corrupted by the
|
||||
; * time assert_failed is called.

Express Logic's ThreadX for STM3240G-EVAL (Cortex-M4 FPU) Evaluation Board
|
||||
|
||||
Using the IAR Tools
|
||||
|
||||
|
||||
*** DEMO VERSION ***
|
||||
|
||||
|
||||
0. About This Version
|
||||
|
||||
This version of ThreadX is for demonstration purposes only and may not
|
||||
be used for any product development, either directly or indirectly. In
|
||||
addition, this demonstration may not be used for any competitive purpose.
|
||||
|
||||
|
||||
1. Installation
|
||||
|
||||
ThreadX for the Cortex-M4 is delivered on a single CD-ROM compatible disk.
|
||||
The entire distribution can be found in the sub-directory:
|
||||
|
||||
\threadx
|
||||
|
||||
To install ThreadX to your hard-disk, either run the supplied installer
|
||||
program Setup.exe or copy the distribution from the CD manually.
|
||||
|
||||
To copy the ThreadX distribution manually, make a ThreadX directory on your
|
||||
hard-disk (we recommend c:\threadx\stm3240g-eval\iar) and copy all the contents
|
||||
of the ThreadX sub-directory on the distribution disk. The following
|
||||
is an example MS-DOS copy command from the distribution directory
|
||||
(assuming source is d: and c: is your hard-drive):
|
||||
|
||||
|
||||
d:\threadx> xcopy /S *.* c:\threadx\stm3240g-eval\iar
|
||||
|
||||
|
||||
2. Building the ThreadX run-time Library
|
||||
|
||||
This demonstration version contains a pre-built ThreadX library, tx.a. The library is
|
||||
intended for demonstration purposes only and thus has the following limitations:
|
||||
|
||||
10 Threads
|
||||
9 Timers
|
||||
2 Event Flag Groups
|
||||
2 Mutexes
|
||||
3 Queues
|
||||
2 Semaphores
|
||||
1 Block Pool
|
||||
1 Byte Pool
|
||||
|
||||
|
||||
|
||||
3. Demonstration System
|
||||
|
||||
The ThreadX demonstration is designed to execute under the IAR debugger on the
|
||||
STM3240G-EVAL evaluation board (STM32F407 processor).
|
||||
|
||||
Building the demonstration is easy; simply open the threadx.www workspace file,
|
||||
make the demo_threadx.ewp project the "active project" in the IAR Embedded
|
||||
Workbench, and select the "Make" button.
|
||||
|
||||
You should observe the compilation of demo_threadx.c (which is the demonstration
|
||||
application) and linking with tx.a. The resulting file demo_threadx.out is a
|
||||
binary ELF file that can be downloaded to flash and executed on the STM3240G-EVAL
|
||||
evaluation board connected via a USB cable to the IAR J-Link JTAG probe.
|
||||
|
||||
|
||||
4. System Initialization
|
||||
|
||||
The entry point in ThreadX for the Cortex-M4 using IAR tools is at label
|
||||
__iar_program_start. This is defined within the IAR compiler's startup code.
|
||||
In addition, this is where all static and global preset C variable
|
||||
initialization processing takes place.
|
||||
|
||||
The ThreadX tx_initialize_low_level.s file is responsible for setting up
|
||||
various system data structures, and a periodic timer interrupt source.
|
||||
By default, the vector area is defined at the top of startup_stm32f40x.s,
|
||||
which is a slightly modified from the base ST/IAR file.
|
||||
|
||||
The _tx_initialize_low_level function inside of tx_initialize_low_level.s
|
||||
also determines the first available address for use by the application, which
|
||||
is supplied as the sole input parameter to your application definition function,
|
||||
tx_application_define. To accomplish this, a section is created in
|
||||
tx_initialize_low_level.s called FREE_MEM, which must be located after all
|
||||
other RAM sections in memory.
|
||||
|
||||
|
||||
5. Register Usage and Stack Frames
|
||||
|
||||
The following defines the saved context stack frames for context switches
|
||||
that occur as a result of interrupt handling or from thread-level API calls.
|
||||
All suspended threads have the same stack frame in the Cortex-M4 version of
|
||||
ThreadX. The top of the suspended thread's stack is pointed to by
|
||||
tx_thread_stack_ptr in the associated thread control block TX_THREAD.
|
||||
|
||||
|
||||

||||
6. Improving Performance
|
||||
|
||||
The distribution version of ThreadX is built without any compiler
|
||||
optimizations. This makes it easy to debug because you can trace or set
|
||||
breakpoints inside of ThreadX itself. Of course, this costs some
|
||||
performance. To make it run faster, you can change the ThreadX library
|
||||
project to enable various compiler optimizations.
|
||||
|
||||
In addition, you can eliminate the ThreadX basic API error checking by
|
||||
compiling your application code with the symbol TX_DISABLE_ERROR_CHECKING
|
||||
defined.
|
||||
|
||||
|
||||
7. Interrupt Handling
|
||||
|
||||
ThreadX provides complete and high-performance interrupt handling for Cortex-M4
|
||||
targets. There are a certain set of requirements that are defined in the
|
||||
following sub-sections:
|
||||
|
||||
|
||||
7.1 Vector Area
|
||||
|
||||
The Cortex-M4 vectors start at the label __tx_vectors and is defined in cstartup_M.s.
|
||||
The application may modify the vector area according to its needs.
|
||||
|
||||
|
||||
7.2 Managed Interrupts
|
||||
|
||||
A ThreadX managed interrupt is defined below. By following these conventions, the
|
||||
application ISR is then allowed access to various ThreadX services from the ISR.
|
||||
Here is the standard template for managed ISRs in ThreadX:
|
||||
|
||||
|
||||
PUBLIC __tx_IntHandler
|
||||
__tx_IntHandler:
|
||||
; VOID InterruptHandler (VOID)
|
||||
; {
|
||||
PUSH {lr}
|
||||
BL _tx_thread_context_save
|
||||
|
||||
; /* Do interrupt handler work here */
|
||||
; /* .... */
|
||||
|
||||
B _tx_thread_context_restore
|
||||
; }
|
||||
|
||||
|
||||
8. IAR Thread-safe Library Support
|
||||
|
||||
Thread-safe support for the IAR tools is easily enabled by building the ThreadX library
|
||||
and the application with TX_ENABLE_IAR_LIBRARY_SUPPORT. Also, the linker control file
|
||||
should have the following line added (if not already in place):
|
||||
|
||||
initialize by copy with packing = none { section __DLIB_PERTHREAD }; // Required in a multi-threaded application
|
||||
|
||||
|
||||
9. FPU Support
|
||||
|
||||
By default, FPU support is disabled for each thread. If saving the context of the FPU registers
|
||||
is needed, the following API call must be made from the context of the application thread - before
|
||||
the FPU usage:
|
||||
|
||||
void tx_thread_fpu_enable(void);
|
||||
|
||||
After this API is called in the application, FPU registers will be saved/restored for this thread if it
|
||||
is preempted via an interrupt. All other suspension of the this thread will not require the FPU registers
|
||||
to be saved/restored.
|
||||
|
||||
To disable FPU register context saving, simply call the following API:
|
||||
|
||||
void tx_thread_fpu_disable(void);
|
||||
|
||||

||||

0. About This Version
|
||||
|
||||
This version of ThreadX is for demonstration purposes only and may not
|
||||
be used for any product development, either directly or indirectly. In
|
||||
addition, this demonstration may not be used for any competitive purpose.
|
||||
|
||||
|
||||
1. Installation
|
||||
|
||||
ThreadX for ST's STM32F4 Discovery (Cortex-M4) is pre-installed in the evaluation
|
||||
package.
|
||||
|
||||
|
||||
2. Building the ThreadX run-time Library
|
||||
|
||||
This demonstration version contains a pre-built ThreadX library, tx.a. The library is
|
||||
intended for demonstration purposes only and thus has the following limitations:
|
||||
|
||||
10 Threads
|

10 Timers
|
||||
10 Event Flag Groups
|
||||
10 Mutexes
|
||||
10 Queues
|
||||
10 Semaphores
|

10 Block Pool
|
||||
10 Byte Pool
|
||||
|
||||
|
||||
3. Demonstration System
|
||||
|
||||
The ThreadX demonstration is designed to execute on the STM32F4 Discovery evaluation
|
||||
board under the IAR Windows-based debugger.
|
||||
|
||||
Building the demonstration is easy; simply make the demo_threadx.ewp project
|
||||
the "active project" in the IAR Embedded Workbench and select the "Make" button.
|
||||
|
||||
You should observe the compilation of demo_threadx.c (which is the demonstration
|
||||
application) and linking with tx.a. The resulting file demo_threadx.out is a binary
|
||||
file that can be downloaded and executed on the STM32F4 Discovery evaluation board using
|
||||
the IAR debugger.
|
||||
|
||||
|
||||
4. System Initialization
|
||||
|
||||
The entry point in ThreadX for the (Cortex-M4) using IAR tools is at label
|
||||
Reset_Handler. This is defined within the STM32 startup code, namely
|
||||
the file startup_stm32f429xx.s. From this entry point, the IAR startup code
|
||||
at __iar_program_start is called. This is where all static and global preset
|
||||
C variable initialization processing takes place.
|
||||
|
||||
The ThreadX tx_initialize_low_level.s file is responsible for setting up
|
||||
various system data structures, and a periodic timer interrupt source.
|
||||
|
||||
The _tx_initialize_low_level function inside of tx_initialize_low_level.s
|
||||
also determines the first available address for use by the application, which
|
||||
is supplied as the sole input parameter to your application definition function,
|
||||
tx_application_define. To accomplish this, a section is created in
|
||||

|
||||
other RAM sections in memory.
|

|
||||
|
||||
The following defines the saved context stack frames for context switches
|
||||
that occur as a result of interrupt handling or from thread-level API calls.
|
||||
All suspended threads have the same stack frame in the Cortex-M4 version of
|

|
||||
optimizations. This makes it easy to debug because you can trace or set
|
||||
breakpoints inside of ThreadX itself. Of course, this costs some
|
||||
performance. To make it run faster, you can change the ThreadX library
|

|
||||
|
||||
In addition, you can eliminate the ThreadX basic API error checking by
|
||||
compiling your application code with the symbol TX_DISABLE_ERROR_CHECKING
|
||||
defined.
|
||||
|
||||
|
||||
7. Interrupt Handling
|
||||
|
||||
The Cortex-M4 vectors start at the label __vector_table and is defined in cstartup_M.s.
|
||||
The application may modify the vector area according to its needs.
|
||||
|
||||
|
||||
7.2 Managed Interrupts
|
||||
|
||||
From version 5.6 going forward, ISRs for Cortex-M using the IAR tools can be written
|
||||
completely in C (or assembly language) without any calls to _tx_thread_context_save or
|
||||
_tx_thread_context_restore. These ISRs are allowed access to the ThreadX API that is
|
||||
available to ISRs.
|
||||
|
||||
ISRs written in C will take the form (where "your_C_isr" is an entry in the vector table):
|
||||
|
||||
void your_C_isr(void)
|
||||
{
|
||||
|
||||
/* ISR processing goes here, including any needed function calls. */
|
||||
}
|
||||
|
||||
ISRs written in assembly language will take the form:
|
||||
|
||||
PUBLIC your_assembly_isr
|
||||
your_assembly_isr:
|
||||
|
||||
PUSH {lr}
|
||||
|
||||
; ISR processing goes here, including any needed function calls.
|
||||
|
||||
POP {lr}
|
||||
BX lr
|
||||
|
||||
Backward compatibility to the previous style assembly ISRs is maintained, which was of
|
||||
the form:
|
||||
|
||||
PUBLIC __legacy_isr_handler
|
||||
__legacy_isr_handler:
|
||||
PUSH {lr}
|
||||
BL _tx_thread_context_save
|
||||
|
||||
; /* Do interrupt handler work here */
|
||||
; /* .... */
|
||||
|
||||
B _tx_thread_context_restore
|
||||
|
||||
|
||||
8. IAR Thread-safe Library Support
|
||||
|
||||
Thread-safe support for the IAR tools is easily enabled by building the ThreadX library
|
||||
and the application with TX_ENABLE_IAR_LIBRARY_SUPPORT. Also, the linker control file
|
||||
should have the following line added (if not already in place):
|
||||
|
||||
initialize by copy with packing = none { section __DLIB_PERTHREAD }; // Required in a multi-threaded application
|
||||
|
||||
The project options "General Options -> Library Configuration" should also have the
|
||||
"Enable thread support in library" box selected.
|
||||
|
||||
|
||||
9. VFP Support
|
||||
|
||||
When applicable, ThreadX for the STM32F4 Discovery (Cortex-M4) supports lazy VFP support, which
|
||||
means that applications threads can simply use the VFP and ThreadX automatically maintains
|
||||
the VFP registers as part of the thread context - no additional setup by the application
|
||||
is required.
|
||||
|
||||
|
||||
10. Revision History
|
||||
|
||||

Express Logic's ThreadX for EK-TM4C123GXL Evaluation Board (Cortex-M4)
|
||||
|
||||
Using the IAR Tools
|
||||
|
||||
|
||||
*** DEMO VERSION ***
|
||||
|
||||
|
||||
0. About This Version
|
||||
|
||||
This version of ThreadX is for demonstration purposes only and may not
|
||||
be used for any product development, either directly or indirectly. In
|
||||
addition, this demonstration may not be used for any competitive purpose.
|
||||
|
||||
|
||||
1. Installation
|
||||
|
||||
ThreadX for EK-TM4C123GXL (Cortex-M4) is pre-installed in the evaluation package.
|
||||
|
||||
|
||||
2. Building the ThreadX run-time Library
|
||||
|
||||
This demonstration version contains a pre-built ThreadX library, tx.a. The library is
|
||||
intended for demonstration purposes only and thus has the following limitations:
|
||||
|
||||
10 Threads
|
||||
10 Timers
|
||||
10 Event Flag Groups
|
||||
10 Mutexes
|
||||
10 Queues
|
||||
10 Semaphores
|
||||
10 Block Pool
|
||||
10 Byte Pool
|
||||
|
||||
|
||||
3. Demonstration System
|
||||
|
||||
The ThreadX demonstration is designed to execute on the EK-TM4C123GXL evaluation
|
||||
board under the IAR Windows-based debugger.
|
||||
|
||||
Building the demonstration is easy; simply make the demo_threadx.ewp project
|
||||
the "active project" in the IAR Embedded Workbench and select the "Make" button.
|
||||
|
||||
You should observe the compilation of demo_threadx.c (which is the demonstration
|
||||
application) and linking with tx.a. The resulting file demo_threadx.out is a binary
|
||||
file that can be downloaded and executed on the EK-TM4C123GXL evaluation board using
|
||||
the IAR debugger.
|
||||
|
||||
|
||||
4. System Initialization
|
||||
|
||||
The entry point in ThreadX for the (Cortex-M4) using IAR tools is at label
|
||||
__Reset_Handler. This is defined within the EK-TM4C123GXL startup code, namely
|
||||
the file startup_ewarm.s. From this entry point, the IAR startup code
|
||||
at __iar_program_start is called. This is where all static and global preset
|
||||
C variable initialization processing takes place.
|
||||
|
||||
The ThreadX tx_initialize_low_level.s file is responsible for setting up
|
||||
various system data structures, and a periodic timer interrupt source.
|
||||
|
||||
The _tx_initialize_low_level function inside of tx_initialize_low_level.s
|
||||
also determines the first available address for use by the application, which
|
||||
is supplied as the sole input parameter to your application definition function,
|
||||
tx_application_define. To accomplish this, a section is created in
|
||||
tx_initialize_low_level.s called FREE_MEM, which must be located after all
|
||||
other RAM sections in memory.
|
||||
|
||||
|
||||
5. Register Usage and Stack Frames
|
||||
|
||||
The following defines the saved context stack frames for context switches
|
||||
that occur as a result of interrupt handling or from thread-level API calls.
|
||||
All suspended threads have the same stack frame in the Cortex-M4 version of
|
||||
ThreadX. The top of the suspended thread's stack is pointed to by
|
||||
tx_thread_stack_ptr in the associated thread control block TX_THREAD.
|
||||
|
||||

6. Improving Performance
|
||||
|
||||
The distribution version of ThreadX is built without any compiler
|
||||
optimizations. This makes it easy to debug because you can trace or set
|
||||
breakpoints inside of ThreadX itself. Of course, this costs some
|
||||
performance. To make it run faster, you can change the ThreadX library
|
||||
project to enable various compiler optimizations.
|
||||
|
||||
In addition, you can eliminate the ThreadX basic API error checking by
|
||||
compiling your application code with the symbol TX_DISABLE_ERROR_CHECKING
|
||||
defined.
|
||||
|
||||
|
||||
7. Interrupt Handling
|
||||
|
||||
The Cortex-M4 vectors start at the label __vector_table and is defined in cstartup_M.s.
|
||||
The application may modify the vector area according to its needs.
|
||||
|
||||
|
||||
7.2 Managed Interrupts
|
||||
|
||||
From version 5.6 going forward, ISRs for Cortex-M using the IAR tools can be written
|
||||
completely in C (or assembly language) without any calls to _tx_thread_context_save or
|
||||
_tx_thread_context_restore. These ISRs are allowed access to the ThreadX API that is
|
||||
available to ISRs.
|
||||
|
||||
ISRs written in C will take the form (where "your_C_isr" is an entry in the vector table):
|
||||
|
||||
void your_C_isr(void)
|
||||
{
|
||||
|
||||
/* ISR processing goes here, including any needed function calls. */
|
||||
}
|
||||
|
||||
ISRs written in assembly language will take the form:
|
||||
|
||||
PUBLIC your_assembly_isr
|
||||
your_assembly_isr:
|
||||
|
||||
PUSH {lr}
|
||||
|
||||
; ISR processing goes here, including any needed function calls.
|
||||
|
||||
POP {lr}
|
||||
BX lr
|
||||
|
||||
Backward compatibility to the previous style assembly ISRs is maintained, which was of
|
||||
the form:
|
||||
|
||||
PUBLIC __legacy_isr_handler
|
||||
__legacy_isr_handler:
|
||||
PUSH {lr}
|
||||
BL _tx_thread_context_save
|
||||
|
||||
; /* Do interrupt handler work here */
|
||||
; /* .... */
|
||||
|
||||
B _tx_thread_context_restore
|
||||
|
||||
|
||||
8. IAR Thread-safe Library Support
|
||||
|
||||
Thread-safe support for the IAR tools is easily enabled by building the ThreadX library
|
||||
and the application with TX_ENABLE_IAR_LIBRARY_SUPPORT. Also, the linker control file
|
||||
should have the following line added (if not already in place):
|
||||
|
||||
initialize by copy with packing = none { section __DLIB_PERTHREAD }; // Required in a multi-threaded application
|
||||
|
||||
The project options "General Options -> Library Configuration" should also have the
|
||||
"Enable thread support in library" box selected.
|
||||
|
||||
|
||||
9. VFP Support
|
||||
|
||||
When applicable, ThreadX for the EK-TM4C123GXL (Cortex-M4) supports lazy VFP support, which
|
||||
means that applications threads can simply use the VFP and ThreadX automatically maintains
|
||||
the VFP registers as part of the thread context - no additional setup by the application
|
||||
is required.
|
||||
|
||||
|
||||
10. Revision History
|
||||
|
||||
08/01/2017 Initial ThreadX version for EK-TM4C123GXL (Cortex-M4) using IAR's ARM tools.

[Trace ID] 4 This 4-byte field contains the ThreadX Trace

contents are 0x54585442 (TXTB). Since it is written as

a 32-bit unsigned word, this value is also used to

determine if the event trace information is in

little or big endian format.

[Timer Valid Mask] 4 Mask of valid bits in the 32-bit time stamp. This

enables use of 32, 24, 16, or event 8-bit timers.

If the time source is 32-bits, the mask is

0xFFFFFFFF. If the time source is 16-bits, the

||||
mask is 0x0000FFFF.
|

[Trace Base Address] 4 The base address for all trace pointer. Subtracting
|
||||
the pointer and this address will yield the proper
|
||||
offset into the trace buffer.
|
||||
[Trace Object Registry Start Pointer] 4 Pointer to the start of Trace Object Registry
|
||||
[Reserved] 2 Reserved two bytes - should be 0x0000
|
||||
[Trace Object Object Name Size] 2 Number of bytes in object name
|
||||
[Trace Object Registry End Pointer] 4 Pointer to the end of Trace Object Registry
|
||||
[Trace Buffer Start Pointer] 4 Pointer to the start of the Trace Buffer Area
|
||||
[Trace Buffer End Pointer] 4 Pointer to the end of the Trace Buffer Area
|
||||
[Trace Buffer Current Pointer] 4 Pointer to the oldest entry in the Trace Buffer.

This entry will be overwritten on the next event and
|
||||
incremented to the next event (wrapping to the top
|
||||
if the buffer end pointer is exceeded).
