Linux/DRA72XEVM: Read DSP printouts on ARM linux terminal

Joakim B

Part Number: DRA72XEVM

Tool/software: Linux

Hi,

We have DRA7xx-evm boards where we run linux on the arm-side. What way do you propose to use to retrieve printouts using either standard printf or Log_print0 from the dsp-core on the linux terminal.

Thanks,
Joakim

If you are loading the DSP cores using remoteproc, you can view the remoteproc traces using the debugfs. Basically:

cat /sys/kernel/debug/remoteproc/remoteprocX/trace0

This document www.ti.com/.../sprac12.pdf has more information in section 3.3 "Linux and Android - Remote Core Traces".

Thanks,
Angela
