We notice rebooting the target has fixed the issue
So Nvidia has done independent testing and is able to replicate this issue? Rebooting isn’t a resolution, it’s a workaround.
As mentioned in my last post, I dug a bit into the MAX96712 deserializer driver in the SDK and I see a TODO comment (cdi_max96712.c line 2583) mentioning that the link lock may take >100ms intermittently. I wonder if this may have something to do with this issue?
As posted last time, here is the syslog:
