I can’t tell what going on with this. It’s better consult with device vendor.
hello @ShaneCCC, i apply a eval adv7282a-m board,and it work fine on our other platform. but when i connect it with tx2, i find the csi receiver cant deinterlacer mipi data right. could u give some advice?
i trace the debug messag:
tracer: nop

hello @ShaneCCC,my chip output 216m hz mipi clk, in other doc i find tx2 is 204mhz clk, is this a problem for my chip?
It’s doesn’t matter. 204 is vi logic run frequency it doesn’t matter with MIPI speed.
HI,@ShaneCCC,I use Oscilloscope catch the 7282am output signal, its a shortpack - line data pack - shortpack -line data pack, but i catch the ov5693 sigal ,it always a line data pack in a frame, is tx2 support 7282am’s frame format?
hi,@ShaneCCC,Now I got help from : https://devtalk.nvidia.com/default/topic/1032730/jetson-tx2/adv7280m-error-pxl_sof-syncpt-timeout-/post/5254339/
Now i can get a ful image,but the line data is not good, and i just can catch 25fps(output 50 fps), the tx2’s compatibility with pal chip is pool, do u have any idea to solve the problem?
Don’t know what you mean data line is not good.
Try to boost the vi clock to try the fps issue.
sudo ./jetson_clocks.sh
sudo su
echo 1 > /sys/kernel/debug/bpmp/debug/clk/vi/mrq_rate_locked
cat /sys/kernel/debug/bpmp/debug/clk/vi/max_rate
echo max_rate > /sys/kernel/debug/bpmp/debug/clk/vi/rate
hi,@ShaneCCC， I tried to clarify the problem.
1.when I Increase delay 20ms in tegra_channel_capture_frame, i can capture a Full frame,but it is something wrong with sample. then i use a fpga csi output 640x480 RGB color bar,tx2 can display well.but i force fpga output 720x576,The phenomenon is the same as adv7282a-m.the color bar is not alignment.
2.i open trace，use v4l2-ctl --stream-count=1 to capture one frame. v4l2 display captured one frame. but the debug message display tx2 received two CHANSEL_PXL_SOF … CHANSEL_PXL_EOF.so my Actual frame rate is half of chip output frame rate。
3.by the way, my fpga csi output 30 fps, but it is same as adv7282am，tx2 can only cap 15fps.
Look forward to your reply。
Check the timestamp of the CHANSEL_PXL_SOF and next CHANSEL_PXL_EOF (frame duration = CHANSEL_PXL_EOF - CHANSEL_PXL_SOF)
This is a frame informatio， Can you help me with the analysis?

From the log the duration about 50ms, the fpga output is about 20fps.
Does boost the vi/emc clock not help?
This method didn’t work.I measure the oscilloscope output it is indeed a 60fps output.
