Help please! nvidia agx orin different emmc model number, cannot restore the existing system image to a new board with a smaller eMMC capacity

[122972335]

board A : emmc(DG4064) bigger capacity, already backed up system.img(image_A);

board B: emmc(TY2964) smaller capacity, need restore image_A;

I have tried some ways, but all failed, as follows:

(1) sudo ./flash -r jetson-agx-orin-devkit internal

(2) add size restore:

sudo ./flash -r -S 60129542144 jetson-agx-orin-devkit internal

(3)

add size back up:

sudo ./flash.sh -r -k APP -S 60129542144 -G agx_orin_image/v6_20260105_testSize/system.img jetson-agx-orin-devkit mmcblk0p1

add size restore:

sudo ./flash.sh -r -S 60129542144 jetson-agx-orin-devkit internal

Could you provide the part number of these 2 AGX Orin module?
Which JetPack SW you’re using?

Is it possible to use lower size than 60129542144?

我现在就是需要将已经制作好的系统镜像（image_A, 从emmc容量更大的板卡备份出来的）烧录到board B(emmc 容量小一些)，可以接受用户使用的emmc空间小一点

lower size is OK. A smaller capacity would also be acceptable, as long as the existing image can be flash to the smaller-capacity board card of the eMMC type

eMMC size differ makes backup and restore fail - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums
