Dear NXP，
We use the L5.4.70_2.3.0_MX8QM Linux release， and follow the guide：https://www.nxp.com.cn/docs/en/user-guide/IMX_LINUX_USERS_GUIDE.pdf
then flash to SD Card：sudo dd if=imx-image-multimedia-imx8qmmek.wic of=/dev/sd bs=1M conv=fsync
Using this SDCard， we can boot the linux os. But, when we check the v4l2 function, Crash occurred.
Details in the attach file : Crash.TXT, the dmesg.
Any idea or suggestions?
Best regards

Try to change boot params， works
元の投稿で解決策を見る
Hello, CYL
Sorry, forgive a sudden reply. I'm having the same phenomenon.
Would you tell me about change boot params.
Best Regards,
Input below commands in uboot command line：
setenv fdt_file xxxx.dtb（a device tree which include the video-in device， I use the hdmi-in dtb file）
saveenv
boot
hope that will take effect for you
Thank you for reply.
I will refer to your procedure.
Regards,
