@xykon Thanks. I've been able to upgrade to 1.18.0 following the instructions. I've been using CLI mode. I will keep using this procedure instead the GUI, which I cannot progress from the Attention page. Thanks again.

@stefan85e Have you tried disabling the safe-boot feature, does this work?

Could you try deleting C:\Users\Stefan\.atom\packages\pymakr\ and re-install the pymakr plugin

@stefan85e That does not show much more than the reboot messages. Since your scripts prints messages, it would be interesting to see the time frame after printing your script's messages and the reboot print-outs. If Atom cannot do that, use a simple terminal emulator like Putty on Windows. The allow to write logs into a file.

@crumble There is no USB stack on the *Py devices. They are connecetd by UART0 of the ESP32 through an USB/UART bridge chip. The driver for that chip used to make problems, but mostly on OS X.
