Hi,
Please try the manual steps to re-flash the Orin Nano developer kit:
Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation
>> Jetson Orin Nano Developer Kit with Super Configuration (NVMe) <<
$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
-c tools/kernel_flash/flash_l4t_t234_nvme.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml" \
--showlogs --network usb0 jetson-orin-nano-devkit-super internal
And see if the super mode is enabled.
For the docker issue, it looks like it is updated per
28.0.0: Cannot start with iptables=true · Issue #49505 · moby/moby · GitHub
Please try again and see if you still hit the issue.
