Part Number: OMAP-L138

Hi,

I am using OMAP-L138 processor for one of our custom board. So how do I check the DSP core is up and running from debug terminal (UART).?

Hi Sharmila,

What OS do you use, Processor SDK Linux or RTOS? Which version?

Hi Sharmila,

I am routing your query to our Linux IPC expert. Response will be updated here.

Hello Sharmila,

Linux uses the remoteproc driver to load other cores. So you can start by searching your boot logs for "remoteproc".

Please reference the SDK 6.3 IPC documentation for more information:
3.7. IPC — Processor SDK Linux Documentation

While the documentation mostly talks about AM57x, it should also apply to OMAP-L138. Note that you will want to modify symbolic link
/lib/firmware/rproc-dsp-fw to point to your DSP firmware.

You can find an example of loading and unloading DSP firmware here:
