Tip for installing 39.2 capsule on 36.x
I just got brand new Jetson Orin Nano and had problems installing firmware and setting up SD card. Booting from USB with image on it would detect that firmware needs update, create capsule, reboot Jetson, install bunch of things and on next reboot just stop. I traced issue to USB drive being automatically kicked down to last spot in boot order and Jetson trying to resume capsule installation from SD card that is not setup yet. I tried rearranging boot order but it didn't work, so what I did is install latest Jetpack ISO image, same like I have on USB drive on SD card, capsule got installed jut fine, then when it came time to install the rest i reformatted SD card and continued with regular installation from the USB drive. Hope it helps someone if they are stuck like I was.
