I am searching for a recent version of FreeRTOS for the Ti LAUNCHXL2-570LC43 eval board. I found this[1] but it’s for the R4 and not the R5 - I am not quite sure if there’s a major difference code-wise here.
You should be able to use this FreeRTOS port - FreeRTOS-Kernel/portable/GCC/ARM_CR5 at main · FreeRTOS/FreeRTOS-Kernel · GitHub. If you are looking for a pre-configured project for your eval board which you can use as a starting point, you can try to use TI code generation tool or you can reach out to TI.
