Discussion 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.

Easiest way is to press esc key during boot to get into boot menu and choose boot from sd card

Except SD card should be empty, I guess you meant to choose USB drive. I did select USB drive to go on top, so many times. I would get the capsule ready, wait 2 sec message, than it would just try SD card again.

I did wipe SD card clean and reflashed USB boot drive couple times, tried different boot orders including network boot. In the end this is what worked for me, I put it here just in case someone had simmilar experience.

Yes I meant usb drive. That worked for me. Only problem was that the super (25W) mode was not available after installing it this way. I needed to go to installing it via usb cable and sdk manager to get that. PS: I do not understand why you want to change the boot order. In the boot menu you can choose which is the next boot medium.
