AMPY / RSHELL not working


I’m trying to get started using the Sipeed M1 Dock, and I have been able to flash the board with new firmware and also execute Python commands via REPL (using screen) and connecting the MaixPy IDE. But when connecting to the board using rshell/ampy/uPyLoader it takes more than just a bit of luck to actually get access to the board.

I have been able to copy a few files to/from the board, but 99% of the time the tools cannot connect. Any idea why?
