How do i move my rootfs to a sata ssd - TX2 Dev board

[gl11]

Hi!

What is the recommended way of moving the rootfs to a sata drive?

And how do i install via sdkmanager or commandline tools
directly to sata (sda1).

i tried via sdkmanager wehere i did skip the flash and did everything else.

then i tried:
sudo BOOTDEV=sda1 ./flash.sh --no-flash jetson-tx2 sda1
which after a while exited with:
Existing flashapp(/home/me/nvidia/nvidia_sdk/JetPack_4.6.1_Linux_JETSON_TX2_TARGETS/Linux_for_Tegra/bootloader/tegraflash.py) reused.

*** no-flash flag enabled. Exiting now… ***

so i manually ran
/home/me/nvidia/nvidia_sdk/JetPack_4.6.1_Linux_JETSON_TX2_TARGETS/Linux_for_Tegra/bootloader/flashcmd.txt

which executed fine. without major errors but left the system broken.

so i again started the sdkmanager and did a default install to emmc.

thanks for any hints.

There is no tool to directly flash to SATA.

To move rootfs to a SATA drive, you need to manually put the rootfs into the SATA drive first. Then using flash.sh to tell the kernel to mount rootfs from the specific path.

The method is actually same as “Flashing to a USB Drive” → “To set up a flash drive manually for using as root file system” in below document. But need to change the device node to your SATA.

And dumping uart log for would be helpful if anything goes wrong.

Well, ok. i followed your links and it got me somewhere.

but no full boot from sata yet!

i can boot the rootfs from sata when manually editing extlinux.conf or by editing uboot vars.

but as far as i can see.

the /boot on mmcblk0p1 gets used by uboot
so the kernel gets loaded from mmcblk0p1.

i can work around that by:
mounting mmcblk01 /somewhereer and then
mount -o bind /somewhere/boot /boot

but how can i completly get rid the mmcblk01 writes?

thanks

Unfortunately, there is no support to fully boot from SATA. Only rootfs on it is possible.

thanks for the help!
