PCIe interrupt error

Sachan Rao

Hello,

I'm having an issue where my C6678 MSIs stop running after a while. I debugged by failing boards and found that the ERR_FATAL bit of PCIe register ERR_IRQ_STATUS_RAW is set. Is there a list of conditions that can cause this bit to get set?

Thanks!

Hi,

Have you configured the C6678 DSP as RC on your setup?

Have you run the test application via CCS to debugged by failing boards?

If you set SERR_EN bit in STATUS_COMMAND register on EP side to enable sending PCI Express error messages to RC.

Thanks,
