We have a custom designed board(tx2),everything is ok at jetPack3.3 .
After a lot of work,we ported sensor driver from jetPack3.3 to jetPack4.2。
But we meet a problem,just like this man:
I am really sure the code of sensor driver is ok,because if I do this:
“echo 1 | sudo tee /sys/kernel/debug/bpmp/debug/clk/nvcsi/mrq_rate_locked > /dev/null”
I can get the picture from video0 successfully.
I tried to disable ECC,useless.
I read some code about vi,nvcsi,v4l2.
So,may be the configuration about sensor at DT is wrong ?
can you just check the dts for me ?
The pipeline about csi input is:
There are 4 pipeline in the board,it means: 4 ar0134,4 tc358748.
The pix_clock of ar0134 is 60Mhz.
The output of tc358748 is:
csi lane speed : 387.5 Mbps/lane
HS Byte clock: 48.4375 Mhz
Data format: Grey, 8Bits
