Hello NVIDIA Developers,
This is somewhat of continuation of my post: Jetson AGX Xavier MIPI CSI-2 without I2C from FPGA
Since the previous post, I have been able to successfully capture a 4-lane MIPI CSI-2 signal from an FPGA on the Jetson AGX Xavier. This has been accomplished at 1080p @ 30 fps and 4k @ 30 fps.
The problem now is that the FPGA signal has been changed from 1 to 2 pixels per clock (PPC). The Xavier is no longer able to capture the stream properly. The trace report shows a CHANSEL_SHORT_FRAME error.

The kernel shows the same repeated messages. Frame numbers do not increment and reports error 131072.
Actually, the frame numbers never incremented properly and reported err_data 0. Video captures were successful under these conditions, so it’s likely to be a different problem altogether

The same dmesg output can be achieved by running Cheese, which outputs a black screen, as pictured below.
Capture attempts using v4l2-ctl freeze. However, I have managed to get some kind of partial output by running the following Gstreamer pipeline for 4k.
gst-launch-1.0 nvv4l2camerasrc ! 'video/x-raw(memory:NVMM), format=(string)UYVY, \
width=(int)3840, height=(int)2160' ! nvvidconv ! \
'video/x-raw(memory:NVMM), format=(string)I420' ! \
nvv4l2h264enc ! 'video/x-h264, \
stream-format=(string)byte-stream' ! h264parse ! \
qtmux ! filesink location=test-4k-2PPC.mp4 -e
This pipeline crashes after 5 seconds, but outputs a single-frame MP4 file that can be converted to JPEG. VLC failed to open this mp4, but I was able to do it with SMPlayer and mpv Media Player. My attempts to capture directly to JPEG using Gstreamer failed, presumably because of the shorter than expected frame. This a screenshot of the single-frame MP4/JPEG file:
The following image was captured from a similar Gstreamer pipeline while streaming a 1 PPC signal from the FPGA. This is what the image should look like, regardless of number of pixels per clock:
I’ve read through the AGX Xavier TRM, particularly about handling 4 PPC / 8 PPC, and, quite frankly, much of it is over my head. Am I able to control these registers? Should I need to worry about making additional changes to the camera sensor driver or device tree to accommodate PPC changes from the incoming stream, or does VI/CSI on the Xavier handle it automatically?
Any advice would be greatly appreciated.
Thanks!
