Thanks for sharing, can I use Minicom to update on Mac? Our previous test was unsuccessful, so there was no Minicom tutorial before.

I only tested it on Linux, I don’t have a Mac to test, but in theory, if the minicom is available for Mac as well it should work in my opinion. Maybe some one with Mac reading this could test it?! :slight_smile:

Great.Thanks for sharing

Just FYI - it worked flawlessly on OctoPi. Not a surprise since OctoPi is just a Linux running on raspberryPi.
