 OS Abstraction Layer (OSAL)

-The OS Abstraction Layer is responsible for providing basic data structures for TinyUSB that may allow for concurrency when used with an RTOS. Without an RTOS it simply handles concurrency issues between the main code and interrupts.
+The OS Abstraction Layer is responsible for providing basic data structures for TinyUSB that may allow for concurrency when used with an RTOS. Without an RTOS it simply handles concurrency issues between the main code and interrupts. The code is almost entirely agnostic of MCU and lives in ``src/osal``.

-The code is almost entirely agnostic of MCU and lives in ``src/osal``.
+In RTOS configurations, tud_task()/tuh_task() blocks behind a synchronization structure when the event queue is empty, so that the scheduler may give the CPU to a different task. To take advantage of the library's capability to yield the CPU when there are no actionable USB device events, ensure that the `CFG_TUSB_OS` symbol is defined, e.g `OPT_OS_FREERTOS` enables the FreeRTOS scheduler to schedule other threads than that which calls `tud_task()/tuh_task()`.

+Dependencies
+^^^^^^^^^^^^
+
+The hardware code is located in ``hw/bsp`` folder, and is organized by family/boards. e.g raspberry_pi_pico is located in ``hw/bsp/rp2040/boards/raspberry_pi_pico`` where FAMILY=rp2040 and BOARD=raspberry_pi_pico. Before building, we firstly need to download dependencies such as: MCU low-level peripheral driver and external libraries e.g FreeRTOS (required by some examples). We can do that by either ways:
+
+1. Run ``tools/get_deps.py {FAMILY}`` script to download all dependencies for a family as follow. Note: For TinyUSB developer to download all dependencies, use FAMILY=all.

 .. code-block::

-   $ git submodule update --init lib

+.. code-block::

-Some modules (e.g. RP2040 and ESP32s2) require the project makefiles to be customized using CMake. If necessary apply any setup steps for the platform's SDK.
-
-Then compile with ``make BOARD=[board_name] all``\ , for example
+Note: some examples especially those that uses Vendor class (e.g webUSB) may requires udev permission on Linux (and/or macOS) to access usb device. It depends on your OS distro, typically copy ``99-tinyusb.rules`` and reload your udev is good to go

-Note: ``BOARD`` can be found as directory name in ``hw/bsp``\ , either in its family/boards or directly under bsp (no family).

+Native CMake support (9.50.1+)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+With 9.50.1 release, IAR added experimental native CMake support (strangely not mentioned in public release note). Now it's possible to import CMakeLists.txt then build and debug as a normal project.
+
+Following these steps:
+
+1. Add IAR compiler binary path to system ``PATH`` environment variable, such as ``C:\Program Files\IAR Systems\Embedded Workbench 9.2\arm\bin``.
+2. Create new project in IAR, in Tool chain dropdown menu, choose CMake for Arm then Import ``CMakeLists.txt`` from chosen example directory.
+3. Set up board option in ``Option - CMake/CMSIS-TOOLBOX - CMake``, for example :code:`-DBOARD=stm32f439nucleo -DTOOLCHAIN=iar`, **Uncheck 'Override tools in env'**.
+4. (For debug only) Choose correct CPU model in ``Option - General Options - Target``, to profit register and memory view.
