dear sir,

Hardware connection:
Analog Video Input---->Video decode ->MIPI---->nano

camera hardware configuration:
1920X1080@30fps

after modify kernel and bsp，Run as below at terminal:
v4l2-ctl -d /dev/video0 --stream-mmap --stream-count=100 --stream-to=video0.yuv

Kernel error reporting as below:

Please enable the debug print of the csi2_fops.c/vi2_fops.c to get more information.

echo file csi2_fops.c +p > /sys/kernel/debug/dynamic_debug/control

Looks like the debug print not enable properly.
Have “sudo su” the enter the echo xxx command.

6

yes, i’m sure using “sudo su” command,Is there any other way to check？

7

Could you disable remove the tegra_channel_ec_recover() from the vi2_fops.c to disable the recovery for check the capture failed status.

8

do you mean comment the tegra_channel_ec_recove() in vi2_fops.c

9

Yes

hi，ShaneCCC，
I comment the tegra_channel_ec_recove() in vi2_fops.c,the kernel msg looks the same as before，

i add printk log in tegra_channel_capture_error()，but I can’t see any information about tegra_channel_capture_error in the dmesg log.
maybe i have some problem before this??

static void tegra_channel_capture_error(struct tegra_channel *chan)
{
u32 val;
int index = 0;
struct tegra_csi_channel *csi_chan;
struct tegra_csi_device *csi = chan->vi->csi;

    /* Find connected csi_channel */
    csi_chan = find_linked_csi_channel(chan, csi);
    printk("%s:%d\n",__func__,chan->valid_ports);

hi ShaneCCC
have some good news,Is it possible that it is a hardware problem？

Do you mean HW of sensor board? Yes, maybe possible.
