Serial Port exposure in MacOS

[HomeACcessoryKid]

Problem Description

When running a container, can you map a (USB)serial port from macOS on the container so that container processes can use it to do things like flash SoC chips, debug via JTAG, etc. ?

Proposed Solution

a command should map the port when starting the image and the port should show up as a /dev/usb-xxxxxx port. Very similar to volumes...

Additional Information

When using the ESP32 idf from the image provided by Espressif, I cannot flash from within the container. I can export the binary file and flash it in macOS.
But realtime debug is not possible.

Maybe this feature has becomes accessible when using Apple virtualisation framework?

This is unlikely to be supported any time soon, as nobody has been able to make it work smoothly in Lima either, which is what Rancher Desktop uses on macOS. The closest we have right now is lima-vm/lima#1317.

Maybe this feature has becomes accessible when using Apple virtualisation framework?

Could be; I haven't looked into it. If you have any skills in that area, maybe you could investigate if/how this could be done in Lima. That will be the prerequisite before it can become available in Rancher Desktop.
