Hangs after (successful?) entering repl #76

I have an esp32 with loboris micropython.
When I completely clear the esp32 and put a fresh flashed image, I can enter mpfshell, access the files and all seems fine. But when I want to enter repl, the system completely hangs.

Here nothing works anymore, I have to kill the mpfshell to get out.

Hmm, this sounds like something isn't initialized properly. Unfortunately, I don't have an ESP32 to test this on, if you could debug I would appreciate it.

seemed to work when I just added the log with debug level, but then after going in and out the repl it hung again.
the log doesn't show much specific.
