如何在不燒錄的情況下如何更新開發板的dtb和Imge?

Hi simon_li_113,

What’s your Jetpack version in use?

Are you asking about flashing the kernel dtb/Image partition only instead of flashing the whole board?
Or you want to update them in runtime?

jetpack 5.2 ,i wan’t to update them in runtime

Do you mean JP5.1.2(L4T R35.4.1)?

You can replace the /boot/Image and /boot/dtb/kernel_XXX.dtb with your new kernel image and dtb respectively in runtime.
and reboot the board to apply the change.
