I am currently porting camera driver from BSP 28.1 to BSP 32.4.3.
Sensor responds, and controls (seem to work) and streaming is started alright, but receiving keeps getting timeout (tegra-vi4 15700000.vi: PXL_SOF syncpt timeout! err = -11).
Upon closer inspection with traces enavbled i can see following:
To me it seems that CSI-2 receiver gets data alright SOF and EOF are seen correctly. SOF traces seem to indicate that SOF is seen at correct interval (roughly 60 frames per second)
In order to verify this I took same trace on working build (with 28.1 BSP).
Sequence seems to be same, tegra_channel_capture_frame traces are not present as they are not present in 28.1. Received line count is same in both cases.
Any ideas why vi_notify_wait() does not get notified about EOF from CSI-2 receiver with 32.4.3 BSP ? Instead it always timeouts, and thus no frames are received by upperlevel software. Device tree is modified (csi-port -> port-index) so it should be alright.
