Fail for Flash the rootfs onto the external SD card

Hi,

We have a demand to flash the external SD card, and below is my steps
1.Put my system into “reset recovery mode”
2.Execute sudo ./flash.sh jetson-tx1 mmcblk1p1 for SD card flash.

After several minutes, the terminal shows the message for a successful result, but when the system couldn’t power on, otherwise, when I remove SD card the TX1 module also couldn’t power on, It seems that this flashing action affect both SD card and TX1 module which could power on originally.
I use sudo ./flash.sh jetson-tx1 mmcblk0p1 formerly for internal emmc flashing, and It always could power on normally.
Is there any action I missed when I went to flash external memory?

Thanks

On your host mount the SD card. See if a full file system is installed, or if perhaps it is just the boot directory (show “ls” from within the mount point of the SD card on host).

Hi Ray0420,

Is this still an issue to support?
Any information can be shared?

Thanks
