There is mipi, but no image on nano.
kernel error log:
echo file csi2_fops.c +p > /sys/kernel/debug/dynamic_debug/control
kernel log：
Hi shaorui,
Which camera model are you using and which driver are you using?
Best regards,
Looks like didn’t enable the debug print in csi2_fops.c
Looks like didn’t enable the debug print in csi2_fops.c. → enable the it on nano?

Do you check the “/sys/kernel/debug/dynamic_debug/control” to confirm it the csi2_fops.c/vi2_fops.c to print debug message?
