currently I am using manual way to upgrade QSPI-NOR with bootloader, by switching Jetson Nano devkit to FC recovery and via microUSB, applying
sudo ./flash.sh jetson-nano-qspi sda1
But for remote usage, how to upgrade QSPI-NOR with bootloader from booted OS (l4t) on Jetson Nano itself?
I know that jetpack on sd card is doing that during first init (especialy when migrating to new partition layout in r32.5 making usb boot possible)…, but in my use case I have my own rootfs
Thanks in advance
PS : i am booting from USB flash drive (sda1) on jetson-nano-devkit
