VI_CSIMUX_CSI_STREAM_0 and CHANSEL FAULT notifications

In debugging the camera driver, it would be super useful to know which error occurred, such as the notifications from 27.7.2 of Parker docs, PIXEL_RUNAWAY, PIXEL_SPURIOUS, PIXEL_LONG_LINE, PIXEL_SHOURT LINE. Some are in VI_CSIMUX_CSI_STREAM_0 register.

Is there a way for the vi driver to log that information?

Thanks,

I’ve tried that, but the only message I see is rtos_queue_peek_from_isr_failed, repeatedly. I was hoping for some more info.

…looking at the forums, I see that CHANSEL_FAULT is emitted with the bitmask when something is wrong.

Thanks!

Good to know, nsabovic. There is also a section of Sensor Driver Debugging Tips inside Development Guide doc.
