J721S2XSOMXEVM: FreeRTOS configuration

Hi Matt,

Could you please let us know which version of the Processor SDK RTOS you are using and version of Code Composer Studio (CCS) you have installed.

Matthew Brown said:

I have Windows11 so I can't easily rebuild the PDK with make.  Is this something that's even possible with WSL for example?

Yes, WSL on Windows 11 works fine for rebuilding the PDK.

Matthew Brown said:

how can I go about pulling the FreeRTOS source into my project so that I can build it with the normal C7000 compiler through CCS?

 Yes you can add the FreeRTOS source files directly to your CCS project and build everything with the standard C7000 compiler. I will try to run an example from my side and get back to you.

Hi,
My PDK currently is version 11.0.0.21.  I see that 11.02.0.06 is out so I will probably be updating to that soon.  I have CCS version 12.6.0.00008.  

I suspect when I used WSL to try to build I failed with errors due to setup or install problems.  The .tar file has problems extracting under Windows and I'm not familiar with all the Linux commands I'd need to run (setup scripts, etc.)
Can you provide instructions on how to install, configure, and build PDK using WSL?

Thanks for running the FreeRTOS build in CCS for C7000.  I'll be glad to have a look at that as well when you have it.  It's probably the better solution for us based on source-control issues.

Thanks,
Matt

Could you please try to extract the .tar.gz inside WSL's Linux filesystem.

 In WSL terminal — copy from Windows Downloads into Linux filesystem first:
mkdir -p ~/ti-sdk
cp /mnt/c/Users/username/Downloads/ti-processor-sdk-rtos-j721s2-evm-11_02_00_06.tar.gz ~/ti-sdk/

 Extract from inside linux filesystem:
cd ~/ti-sdk
tar -xzf ti-processor-sdk-rtos-j721s2-evm-11_02_00_06.tar.gz

After modifying FreeRTOSConfig.h, could you please try these steps to rebuild the FreeRTOS library.

Step 1 — Set compiler paths
export C7X_GEN_INSTALL_PATH=~/ti/ti-cgt-c7000_5.0.0.LTS
export TOOLCHAIN_PATH_R5=~/ti/ti-cgt-armllvm_4.0.4.LTS

Step 2 — Delete the pre-built library to force recompile

rm ~/ti-sdk/ti-processor-sdk-rtos-j721s2-evm-11_02_00_06/pdk_j721s2_11_02_00_15/packages/ti/kernel/lib/j721s2/c7x_1/release/ti.kernel.freertos.ae71

Step 3 — Rebuild

make -C ~/ti-sdk/ti-processor-sdk-rtos-j721s2-evm-11_02_00_06/pdk_j721s2_11_02_00_15/packages/ti/build \
freertos \
BOARD=j721s2_evm \
SOC=j721s2 \
CORE=c7x_1 \
BUILD_PROFILE=release \
BUILD_OS_TYPE=freertos

For R5F cores, change c7x_1 → mcu2_0 (or whichever R5F core) and the library extension changes from .ae71 → .aer5f.

Thanks,
I will try these and let you know.
Matt

Hi Shabary,
I think I'm missing a step here.  When I run the make command I get back:

I don't have a /home/mbrown/ti/ti-cgt-c7000_5.0.0.LTS folder.  Is this a separate build tools I need to do?

I have a /ti-cgt-armllvm_4.0.4.LTS folder but it's in home/mbrown/ti-sdk/ti-processor-sdk-rtos-j721s2-evm-11_02_00_06/ - it came with the SDK

Thanks,

The error No such file or directory for ar7x means the C7x Code Generation Tools (ti-cgt-c7000_5.0.0.LTS) is not installed. This is a separate download — it does not come bundled with the SDK.
You can download it from: www.ti.com/.../C7000-CGT

The ARM LLVM toolchain (ti-cgt-armllvm_4.0.4.LTS) is already in your SDK folder, so that part is fine.

When you export the path, make sure you are exporting both the path correctly as in your system for the build systems to use that.
