hello liuzhiyuan0821,
to summarize,
here’re test steps we used.
$ sudo ./flash.sh -r -k APP -G clone.img jetson-agx-orin-devkit mmcblk0p1
$ mv bootloader/system.img bootloader/system.img-backup
$ cp clone.img bootloader/system.img
$ sudo ./flash.sh -r -k APP jetson-agx-orin-devkit mmcblk0p1
please see-also Topic 215526, and apply the patch,
please update APP partition’s allocation_attribute to 0x808
if the image size is larger than default.
you may ignore system.img.raw
file, instead, please use sparse image to flash the platform.
please check above test steps, we use -k APP
to update APP partition only.
