TDA4VM: TDA4VM

Hello,

To start off, I recommend taking a look at our SDK RTOS, which contains all of the information for building, linking and running programs on the R5F cores.

https://www.ti.com/tool/download/PROCESSOR-SDK-RTOS-J721E

You can take a look at the documentation to get started, but some background on the modules provided in the SDK:

1) MCUSW - Contains the MCAL drivers we deliver for the TDA4VM device, examples and small demos

2) PDK - Contains many low-level driver for peripherals, many of the foundational components in our framework like bootloaders, register definitions (CSL), etc.

start up code files,

Look in the pdk/packages/ti/csl/arch/r5 for startup code files for the R5F core

make files and linker configuration details

The main build folder in the PDK is pdk/packages/ti/build.

Procedure to build R5F code

Documented in the PDK here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_02_00_05/exports/docs/pdk_jacinto_08_02_00_21/docs/userguide/jacinto/getting_started.html

Please let me know if you have a specific component you are looking for.

1)How main() function getting called in R5F?

It will jump to main from the initialization code. You can use the CSL arch/ folder as a reference for the _c_int00, see pdk/packages/ti/csl/arch/r5/src/startup/boot.asm.

The compiler also gives a good explanation of this, depending on the one you are using. Here is the one available in the latest SDK: https://software-dl.ti.com/codegen/docs/tiarmclang/compiler_tools_user_guide/compiler_manual/runtime_environment/system-initialization-stdz0543503.html?highlight=main

Is it possible to build separate source code for R5F and flash it ?

If you want to load it onto the flash, you can follow the OSPI boot, detailed here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/mcusw/mcal_drv/docs/drv_docs/mcusw_c_ug_top.html#mcusw_run_sbl_j721e_ospi

Is it possible to build source code of R5F on windows machine?

If yes how to preform the same? Which tools needed(Eg.CCS)?

If you wish to build one Windows, this is possible. You will need to download the windows compiler tools, located alongside the SDK RTOS download:

You can replace the compiler tools in the SDK with the ones from the download.

3)How R5F core getting started in boot sequence? If any References will be useful for understanding.

There are two ways we support booting the Board, which includes the R5F cores, SBL and SPL. SBL is documented here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_02_00_05/exports/docs/pdk_jacinto_08_02_00_21/docs/userguide/jacinto/family_cfg/jacinto/index_boot_jacinto.html

4)Are there any documents which will provide us information on how to merge/integrate classic AUTOSAR vector stacks with MCSW?

Vector's documentation and deliverables should show how to do this, they have a tool that will integrate our MCAL into their stack, called Third-Party-Integration-Tool currently. It would be best to get this information from them.
