Unknown platform error Jetson Nano 2 GB

[pythonli]

Trying to get Retropie up and running on Jetson Nano which runs Ubuntu 18.04.5 LTS.

Everything is installed and I know I have to set the platform when I launch the Retropie script.

This fixes that:
sudo __platform=jetson-nano ~/RetroPie-Setup/retropie_setup.sh

My question is this. Once I'm in emulation station and I navigate to the retropie menu, every menu option I pick returns the Unkown platform error. Is there any way I can hardcode the __platform=jetson-nano or somehow edit the scripts the menu options are running to include the __platform=jetson-nano?

Thanks in advance!

Support for Jetston Nano is preliminary (added recently). Can you check why your board is correctly identified by RetroPie-Setup from /sys/firmware/devicetree/base/model ?

@mitu according to the file it says "NVIDIA Jetson Nano 2GB Developer Kit" which is correct.

Not quite, the system identification looks for NVIDIA Jetson Nano Developer Kit, without the 2GB in the middle. You can modify the system recognition function and add the extra string, then check if your board is recognized as jetson-nano.

                    case "$model" in
                        "NVIDIA Jetson Nano Developer Kit"|"NVIDIA Jetson Nano 2GB Developer Kit")
                            __platform="jetson-nano"
                            ;;
                        icosa)
                            __platform="tegra-x1"
                            ;;
                    esac
