Dear Forum,
I know this might have been reported/discussed a gazillion times but I'm desperate with my brand new Nano ESP32. It started that uploading a sketch (from Examples) ended in the well known Error 74, using my MackBook Air M1 and Arduino IDE 2.3.2 - switching to my NUC with Ubuntu 22.04 LTS and managed to upload once. Returning to my MacBook and tried a sketch I am developing for the Atmel Nano V3 and then the trouble started: the USB ports shows up and disappears every couple of seconds. On the Mac as well as on the Linux NUC. On Linux, dmesg shows that every second the USB device is found and deactivated in turn. It appears the Nano ESB 32 is caught in an endless reset loop. I tried to burn the Bootloader using the IDE and a wire between GND and B1 and since then I get the same result and "Invalid Header 0xffff....."
Surprisingly, I can install the Micropython firmware and connect with the Arduino Lab for MicroPython and run a simple sketch. Burning the Arduino Bootloader for C++ and the problem shows up again. I wonder if I now have a Micropython only Nano ESP 32 and if it is worth having getting another Nano ESP 32. Maybe there is something wrong with the firmware provided by the Arduino IDE? That Nano ESP32 is brand new. Not a huge investment, but still kind of a bummer.
Reason why I want to switch vom Nano to Nano ESP32 is that I'm starting to run short of memory.
Kind regards
Michael
