Return the root back to emmmc

I’ve recently followed the instructions found in this repository to switch the rootfs to a NVMe SSD on a custom board for Jetson AGX Xavier.

Now I want to revert back to booting from emmc but can’t find a way to do this.

In the instructions given in file it is stated that

If you want to boot from SD again, remove the file /etc/setssdroot.conf from the SD card

But file setssdroot.conf is in the emmc, where I don’t have access anymore. I know I must be missing sth basic, could someone please help? Is there a way to delete the file so that it boots from emmc again?

Many thanks in advance.

You can still access. Just mount /dev/mmcblk0p1. That node is your emmc.

Great, thank you!
