Tegrarcm_v2 fails with return value 8

Did you ever try with sdkmanager? Or you always use flash.sh?

Please let sdkmanager auto detect your board type and do the flash. I don’t think it would be hardware issue happened on all 3 AGX.

using sdkmanager works fine, but I need to use the flash script

I guess you used the wrong board config when running with flash.sh.

Sdkmanager uses same tool as flash.sh.

Comparing the log may help find out the clues.
