I was able to flash my ESP01 (1MB of Flash) with micropython:

There was no error. I used both Thonny and "Mu Editor" in order to attempt to access the REPL but without luck.
I can connect to the device via picocom, but I am stuck on the following "screen":

I would expect to be able to "CTRL + C" here right into the python shell. But that does not work either.
