我想请问，jetson nano 有没有办法知道传进来的sensor数据的宽高，[ 2082.933834] tegra-camrtc-capture-vi tegra-capture-vi: corr_err: discarding frame 3440, flags: 0, err_data 131072
[ 2082.955676] tegra-camrtc-capture-vi tegra-capture-vi: corr_err: discarding frame 3441, flags: 0, err_data 131072
数据是已经正常接收到了的，只是因为ebd的关系，如果数据和我在驱动中设置的如果差几行（哪怕一行），我就无法接收，我能怎么判断现在的数据是多少宽高

hello 2668729889,

please give it a try follow below steps to enable VI tracing logs.
it’s toggled the logs level, which should report more details about the frame packet status, and also error flags,
however, it still not reporting width/height straightforward.

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
echo 1 > /sys/kernel/debug/tracing/events/freertos/enable
echo 2 > /sys/kernel/debug/camrtc/log-level
echo > /sys/kernel/debug/tracing/trace
cat /sys/kernel/debug/tracing/trace

jetson nano无法解析空行的febd,rebd和ob数据吗？我是一定要配置sensor的寄存器，把它填成data type吗，不然nvidia就会解析报错，这有什么方法解决吗

may I know what’s the real use-case, please share the logs for reference.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Is this still an issue to support? Any result can be shared?
