AGX Orin use massflash image to flash,boot failed

hi nv
为了将问题描述清楚,我将使用中文
我们通过参考/Linux_for_Tegra/tools/backup-restore/README_backup_restore.txt制作了一个backup image
操作步骤如下
sudo ./tools/backup_restore/l4t_backup_restore.sh -b -c
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --use-backup-image --no-flash --massflash mmcblk0p1
解压image包后,使用如下命令刷机
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash
如果AGX Orin模块之前已经被刷过有系统了,那么刷机后会启动失败
我们发现用这种方式刷机不会去擦除emmc,并且也无法使用擦除命令
请帮忙看下,谢谢

Hi yougang.hu,

Please try below commands:

$ sudo ./tools/backup_restore/l4t_backup_restore.sh -b -c jetson-agx-orin-devkit
$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --use-backup-image --no-flash --massflash 1 jetson-agx-orin-devkit
$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash 1

hi nv
I have tried these commands, emmc is not erased
flash_1-4_0_20221116-142014.log (65.8 KB)

how did you know the emmc is not erased? If you flash with A and then flash backup image B and you still see the content is A?

hi nv
您说的这种情况暂没发现过
我们是根据以下情况判断emmc没有擦除
1.没有系统的新模组用backup image去刷机开机无问题,已刷过机的模组用backup image刷机会概率开不了机
2.对比了initrd刷机的Log,会有如下擦除的信息,而使用backup image刷机,不会有这个信息

Erasing 64 Kibyte @ 10000 – 0 % complete
Erasing 64 Kibyte @ 20000 – 0 % complete
Erasing 64 Kibyte @ 30000 – 0 % complete
Erasing 64 Kibyte @ 40000 – 0 % complete

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

已刷过机的模组用backup image刷机会概率开不了机

Is there any log for this case? I mean device boot log.
