Flash Jetpack 5.0.2 to SATA SSD

[geoff.s]

I’ve put in a support request to Seeed Studio. Will see if they can help.

But further digging suggests the problem is due to the SATA drive being connected via a USB hub on the board which cboot doesn’t fully enumerate for mass storage devices. Seems to be a common issue - found many threads on this forum relating to cboot and usb drives. Typical example from Boot rootfs from USB drive or SD:

Cboot isn’t enumerating the mass storage devices properly. It’s finding the hubs and testing them for mass storage which of course will fail. It never goes on to the connected devices to find the actual USB mass storage devices that may be connected to the hub.

So it looks like you still need to have the APP partition on the sdcard or emmc.

Having said that you do not need to have the rootfs partition on the sdcard or emmc. The APP partition only needs to have the /boot directory on it not the whole root filesystem. What I do is to have a basic root filesystem on the sdcard/emmc and have the /boot/extlinux/extlinux.conf APPEND line use root=/dev/sda1 where sda1 is the real root partition on a USB stick (or nvme or whatever) then in /etc/fstab mount /dev/mmcblk0p1 on /boot.

I’ve tried a few things without luck. It’s not clear to me exactly how to split the /boot directory and rootfs partition between emmc and SATA drive.
