Hi Wayne,
I have experienced two separate issues when attempting to flash from an Ubuntu 20 machine:
- USB Timeout
- RTELink permission errors
I attempted flashing both via SDKM and manually with
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1 -c ./tools/kernel_flash/flash_l4t_nvme.xml -S 200GiB --showlogs --erase-all jetson-orin-nano-devkit nvme0n1p1
