ThreadX RTOS for Renesas H3e R7 Core

Question

Hello,

I would like to run a ThreadX-enabled application on the R-Car H3 board, specifically on the Cortex-R7 core, while using Yocto Linux. Could you please confirm if I need to rebuild the H3 application with Cortex-R7 enabled? If so, I would greatly appreciate any links or resources you can share to guide me through the process.

Hello,

Thank you for posting in Microsoft Q&A.

Based on the description, I understand your question is related to ThreadX RTOS for Renesas H3e R7 Core.

Try rebuild your application with Cortex-R7 support enabled to run a ThreadX-enabled application on the R-Car H3 board's Cortex-R7 core while using Yocto Linux.

You need the appropriate toolchain for building applications targeting the Cortex-R7 core. You can use the GNU Arm Embedded Toolchain or similar. Modify your Yocto build configuration to include support for the Cortex-R7 core. This involves setting the appropriate machine and tune features in your Yocto recipes.

Port ThreadX to the Cortex-R7 core if not already done. You can use the Cortex-R5 port as a base since the R7 is similar to the R5. Rebuild your application with the Cortex-R7 target. Ensure that your build scripts and makefiles are configured to use the Cortex-R7 compiler flags.

Have a nice day.

Best Regards,

Molly
