Hello,

we have an custom carrier board with a Nvidia Orin NX running L4T-36.4 (JP6.1). The ZEDx camera is connected to the board through a MAX96724 GMSL deserializer. The system is running at MAXN.

The modes are listen in nvargus:

When I try to run

v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=5

it never terminates and dmesg reports a lot of errors:

I tried to enable kernel tracing:

modprobe rtcpu_debug
echo 1 > /sys/kernel/debug/tracing/tracing_on
echo 30720 > /sys/kernel/debug/tracing/buffer_size_kb
echo 1 > /sys/kernel/debug/tracing/events/tegra_rtcpu/enable

cat /sys/kernel/debug/tracing/trace

and the trace shows:

I can’t get any video data from this sensor.

hello marcus.huenerbein,

the PHY interrupt show the DPHY deskew calibration not complete, it might due to the calibration sequence length is not long enough.
please refer to developer guide, SerDes Pixel Clock, you may double check the serdes_pix_clk_hz property settings.

Hello JerryChang,

Thank you for your quick answer.
Setting the correct value for serdes_pix_clk_hz fixed the CORRECTABLE_ERR message.

The VIFALC_TDSTATE message persists and I’m getting no video from this camera.

Am I correct in my assumption that VIFALC_TDSTATE means that no valid buffer data was received ? Is there documentation for the various (error) messages?

Thank you.

hello marcus.huenerbein,

that’s not harmful message.


the issue should be there’s no validate frames received by VI engine,
let me share some VI tracing logs with a success image capture as an example,
here must be one pair of CHANSEL_PXL_SOF/CHANSEL_PXL_EOF to indicate a frame has detected by VI engine.
afterwards, it’s ATOMP_FRAME_DONE to indicate it’s complete writing a frame to memory.
for instance,
