Jetson TK1 : L4T : move rootfs to SATA Disk

Hello,

I have Jetson TK1 with newest L4T on eMMC. I want to move this fileSystem to SATA Disk.

I’m going to move the file system on the disk 2.5 " . The /boot could remain on eMMC, but rest would like to transfer 1:1 to disk drive (2,5" SATA).

What would be the simplest solution ?

  1. dd (how) from eMMC to SATA dd if=/dev/{eMMC} of=/dev/{sata} ?
  2. http://demotomohiro.github.io/hardware/jetson_tk1/setup/sdcard.html
  3. other ?

So long as you use u-boot, and /boot remains on eMMC, ordinary file copy (taking care to preserve permissions and other file traits) works. The /boot/extlinux/extlinux.conf can then just be edited for a new root= (or a second entry added to preserve the original as a rescue).

Just for illustration, if you were on your host and unpacked sample rootfs to a mounted SATA drive, the apply_binaries.sh could then be invoked using the “–root ” to the SATA drive and you would have a default install (other than being on SATA). Keep in mind that you need root authority to preserve permissions, as well as to create or manipulate device special files.

Thx a lot. Works.
