[MPC8640D]:Unable to initialize sRIO

Arathi — Fri, 03 Mar 2023 07:23:51 GMT

Hi NXP Support Team,

We are having a custom board with MPC8640D PowerPC architecture processor.
A sRIO switch is connected to this processor.

While loading our custom Linux image we are unable to initialize the sRIO and we are getting segmentation fault.

Attaching the log file for your reference.
Please find the highlighted sRIO init failing part

Please help me resolve this issue

Regards,
Arathi

Please refer to the following update from the AE team.

Line 180: fsl-of-rio: probe of e00c0000.rapidio failed with error -67

In the boot log, there are errors reported. Due to we haven't the board and software to reproduce, I suggest customer to add some debug message in rapidio driver, check the failed errors first.
