Cannot connect to Apalis iMX8 Ixora board over serial connection with VSCode Torizon extension

I’m confused are you trying to transfer the docker images via network/ssh or via serial UART? You mention both, but these are very different things.

Generally speaking you can use docker save/load as described here: Deploying Container Images to TorizonCore | Toradex Developer Center

This turns your docker image into a tar file that can then be moved around as you would any other file.

Best Regards,
