Unreliably entering raw REPL mode (possibly due to reset?)

[pn2new]

I use pyboard.py to transfer files to my board, either using the command line or importing Pyboard from my own python script. In both cases, scripts fail regularly to enter raw REPL mode. I tried using soft_reset or not, but this does not solve the problem.

The data that is printed before the exception is raised, is this:

This is the message that is printed after a reset (I can trigger this with machine.reset()).

What could be the reason for this behaviour?

Have you tried mpremote?

You can adjust the watchdog timer settings in your MicroPython code:
import machine
machine.WDT(timeout=0) # Disable the WDT
