Hello,
We have a tc358749 hdmi2mipicsi on our carrier board for tx2,after modify kernel driver code,we can confirm tc358749 is worked for 1080p@60fps hdmi video(read tc358749 video check registers), but on tx2 mipi csi we can’t grab 1080p@60fps video stream.
tc358749 output is 4lane mipi-csi connect to tx2 csi-port 2 and 3.
bellow is trace log, What’s wrong with my modification.

hello suchb,
according to VI tracing log, which shows spurious data stream failures.
tag:CSIMUX_STREAM channel:0xff frame:0 vi_tstamp:78096330409 data:0x00000100
were you able to enable test-pattern-generator to narrow down the issue.
also, some experience shows that there might be additional metadata embedded into streaming, could you please checking with oscilloscope.
thanks

hello suchb,
according to below tracing logs,
it’s good news that start-of-frame is recognized, but the frame length did not match VI engine’s expectation.

CHANSEL_SHORT_FRAME failure means the actual coming frame length of signaling is less then expect.
since VI engine allocate buffers with the device tree settings, such as active_h.
could you please have try to reduce the active_h property settings to check the results.
thanks

JerryChang, Thank you very much.
Now tc358749 on my board is working.
