Part Number: AM5718

Hello Champs,

SW: RTOS SDK 04.01.00.06 (26 Sep 2017) and the latest version SDK 08.01.00.09.

Customer wants to run DSP code from OCMC_RAM1, but it prompts below errors:

[21579.679926]omap_hwmod:mmu1_dsp1: _wait_target_disable failed

[21583.879970]omap_hwmod:mmu0_dsp1: _wait_target_disable failed

DSP SECTIONS：

The same DSP code can run on L2SRAM、EXT_CODE、EXT_DATA、TRACE_BUF.

Can the DSP code run from OCMC_RAM1? Is there some special configurations?

Thanks

Thanks for posting your question to TI processor's E2E forum. The expert assigned to this thread is out of office due to public holidays in India today. Please expect a response by the end of this week.

Hi Shine,

Not clear on the SDK version here. Can you please mention again, which version is being used here?

Also, looks like you are trying to load the DSP form Linux using remoteproc. Did you try loading the application in a standalone manner? Does that work?
Want to isolate if the issue is in loading with Linux or the application itself?

Customer did the test on both SDK 04.01.00.06 and SDK 08.01.00.09, the result is the same.

Customer has successfully loading the application in standalone manner. It can run on L2SRAM、EXT_CODE、EXT_DATA、TRACE_BUF. He just modified the program.setmap[".text"] = "L2SRAM" to program.setmap[".text"] = "EXT_CODE"

Thanks
