esp32-mini-1 boot loop

[segovo]

Hello!

I'm having problems with the esp32-devkitm-1 using the Arduino IDE.

Flashing seems to work successfully with no errors, the serial monitor, however, shows that it's stuck rebooting over and over.

This is the log:

Using the exception decoder tool for esp32 I was able to decode the expectation:

Code: Select all

Unfortunately, these results don't seem to say much.

Any insights?

There's your issue. I think Arduino has an option to select a single-core board, but I don't know Arduino good enough to know for sure.

Thank you!

It's working now!


For future reference, I got it working (on my Windows 10 computer) by copying and replacing the tool folder located at

C:\Users\<myuser>\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.6\

with the files from:

https://github.com/lbernstone/arduino-esp32-solo

Glad to hear you solved it, and thanks for sharing the solution!
