1 I am tryimg to port a new camera(OV4689) for IMX8M Plus

2 refer to AN13713.pdf，download isp-imx and isp-vvcam（SDK version：L5.15.71_2.2.0）

3 isp-vvcam:

3-1 git clone https://github.com/nxp-imx/isp-vvcam.git -b lf-5.15.71-2.2.0

3-2 refer to os08a20，add OV4689 driver to "isp-vvcam/isp-vvcam/vvcam/v4l2/sensor/ov4689"

3-3 add private ioctl for OV4689

3-3 export KERNEL_SOURCE_DIR=/home/keng/imx8mp/kernel/linux-imx/

3-4 ./build-all-vvcam.sh v4l2

3-5 scp modules/*.ko root@192.168.12.10:~

3-6 update .ko to /lib/modules/[kernel git commit id]/

3-7 reboot the system

4 isp-imx:

4-1 wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/isp-imx-4.2.2.19.0.bin

4-2 ./isp-imx-4.2.2.19.0.bin --auto-accept

4-3 refer to os08a20，add OV4689 code(drv and xml) to isp-imx/isp-imx-4.2.2.19.0/units/isi/drv/ov4689/

4-4 ./build-all-isp.sh Release Full

4-5 scp -r build_output_release_Full/ root@192.168.12.10:~

4-6 update build_output_release_Full/opt/bin to /opt/imx8-isp/bin/

4-7 reboot the system

4-8 check the isp service（ps -x | grep isp）

4-9 run test app (/opt/imx8-isp/bin/video_test -w 2688 -h 1520 -f RAW8 -t 2 -m 0)

May I ask which step is causing the problem？Unable to locate the code location of the error message

May I ask if you can provide some ideas？Thank you very much！！

Hello,

You have to build the full-image in yocto, it coming with the ISP-imx.

Hello：
1. I know that isp-imx and isp-vvcam are build by yocto
2. The above process is not related to whether it is in yocto or not(the same transplantation method)，
and AN13713.pdf explain how to add new camera
3. I'm just not sure where this error message comes from，maybe it's isp_media_server
4. Attempted to add pr_info to the kernel driver(ov4689.c in isp-vvcam)，It looks like it's working properly
5. If the key code of the error message can be located, it should be able to solve this problem

Can you provide some ideas or methods? Looking forward to your reply!
