Hi,

Do you want to load the M4 code from Linux or just run/debug it on the M4?

i have evm that run by linux on arm. in addition to OS, i want to run a C program on cortex M. in other words, i want to have arm and cortex that both of them are engaged in the task execution

Hi, Saman,

M4 only supports programs running under RTOS. If you have the executable built. The remoteproc process on ARM will look for the files, dra7-ipu1-fw.xem4 and dra7-ipu2-fw.xem4, to download to the M4 cores during Linux Kernel boot up. For RTOS related topics, please refer to Processor SDK RTOS Software Developer Guide at processors.wiki.ti.com/.../Processor_SDK_RTOS_Software_Developer_Guide.

Just to add to Rex`s comments, other the RTOS, M4 can also run bare-metal code. The SDK and documentation provides several examples for this,

For Simple hello world with no OS on M4 refer:
processors.wiki.ti.com/.../Processor_SDK_Bare_Metal_Examples

For RTOS based examples:
processors.wiki.ti.com/.../Processor_SDK_RTOS_Examples

For driver examples, refer :
processors.wiki.ti.com/.../Rebuilding_The_PDK

For IPC examples refer:
processors.wiki.ti.com/.../AM572x

Hope this helps.

Regards,
Rahul
