Hi,

I need to free up the M.2 slot where the NVMe flash module is installed right now (for a PCIe camera). So I want to move it to a USB housing and boot from there. I think I need to adapt the /boot/extlinux/extlinux.conf on /dev/nvme0n1p1 (kernel command line root=/dev/...). Anything else?

And, the eMMC partition contains the same extlinux configuration onthe /dev/mmcblk0p1 partition. Do I need to change it also?

Another way would be to reinstall the JP via l4t_initrd_flash.sh. Is it sufficient to replace the nvme0n1p1 entries with the device name of the USB device and use the same flash layout xml file?

Please directly try initrd flash. Your first method to modify extlinux.conf on nvme won’t really boot things from usb.
