Hello all,
I have been trying to get the raw frame data from the OV5693 image sensor in the Jetson TX2 platform board using my custom v4l2 application. The driver configurations are default in the Jetson board itself. The following is the OV5693 driver configs
mode0 { // OV5693_MODE_2592X1944
mclk_khz = "24000";
num_lanes = "2";
tegra_sinterface = "serial_a";
phy_mode = "DPHY";
discontinuous_clk = "yes";
dpcm_enable = "false";
cil_settletime = "0";
active_w = "2592";
active_h = "1944";
mode_type = "bayer";
pixel_phase = "bggr";
csi_pixel_bit_depth = "10";
readout_orientation = "90";
line_length = "2688";
inherent_gain = "1";
mclk_multiplier = "6.67";
pix_clk_hz = "160000000";
gain_factor = "10";
min_gain_val = "10";/* 1DB*/
max_gain_val = "160";/* 16DB*/
step_gain_val = "1";
default_gain = "10";
min_hdr_ratio = "1";
max_hdr_ratio = "1";
framerate_factor = "1000000";
min_framerate = "1816577";/*1.816577 */
max_framerate = "30000000";/*30*/
step_framerate = "1";
default_framerate = "30000000";
exposure_factor = "1000000";
min_exp_time = "34";/* us */
max_exp_time = "550385";/* us */
step_exp_time = "1";
default_exp_time = "33334";/* us */
embedded_metadata_height = "0";
};
I’m able to take the stream in v4l2-ctl. My v4l2 application works well in my Ubuntu PC and I’m able to successfully save my .raw images. If I run the same application in TX2 platform, I’m not able to queue the buffers.
I enabled the trace logs using the following website:
https://elinux.org/Jetson/l4t/Camera_BringUp
I’m getting the following trace log:

In the above trace log I’m getting the PIX_SOF (CHANSEL_FAULT) bit specified in the bit index. I assume that this error corresponds to no start of frame buffer from the image sensor.
Is there any way I can enable other logs to view why there is no queue and dequeue of the v4l2 buffers ?
Is this issue due to some wrong configs in the driver or in the device tree ?
I’m stuck on how to proceed with this issue specific to TX2.
Thank you.
