I use a OV5647 module in LINUX SDK on D3G board. I use v4l2-ctl to grab a YUV but the picture seems not correct. I try to use gst-launcher instruction as github Doc described, but failed. Please help check is the LINUX SDK OK for OV5647 module testing ? ---

Hello, Could you please let us know which camera module you are using and the image (FW) version that was flashed to the D3-G via FWDN? Please share the exact commands you used for camera capture and for running the gst-launch pipeline. Please also share the error logs generated when executing the commands. The capture must be performed in **UYVY format**. Below is an example capture command: ```auto v4l2-ctl --device 0 --set-fmt-video width=1640,height=1232,pixelformat=UYVY --stream-mmap --stream-to ./1640x1232.UYVY --stream-count 5 ``` Thank you. ---

Are you running this from a terminal connected via the UART debug port? Before executing the gst command, please run: ```auto export XDG_RUNTIME_DIR=/run/user/root ``` Then, please try running the gst command again. ```auto gst-launch-1.0 v4l2src device=/dev/video0 io-mode=2 ! video/x-raw,format=NV12,width=1280,height=720,framerate=30/1 ! videoconvert ! waylandsink fullscreen=true ``` It appears that you have flashed a Yocto image. The `v4l2-ctl` command is not available because the `v4l-utils` package is not included in the Yocto build. Please copy the attached file to the board and install it using `dpkg -i`, then proceed with testing. [v4l-utils\_1.22.1-r0\_arm64.deb](https://mytelechips-my.sharepoint.com/:u:/g/personal/su_nam_telechips_com/IQApl5Tymmm_T6mWU_Vua0-qAcKfZxcStRaOQdgt6RX6_rk?e=pkYwBO) Thank you. ---

Old SDK is working OK, but after my building SDK1.3, even download/fwdn prebuilt image 1.3, the camera preview is FAIL(same HW old sdk is OK), log: [gst-error.txt](https://community.topst.ai/uploads/short-url/5DMsVmuB9GUW4DjJIAsqVljvsG5.txt) (85.8 KB) ---

Thanks, we see that when login use root/root, the camera working OK. Thanks.
