ESP Exception Decoder for ESP32 Wrover Module

Development Tools IDE 1.x
1

I get the error message "Target not found for 'ESP32 Wrover Module' when I click on ESP Exception Decoder.

I followed all of me-no-dev's instructions. The sketchbook location is C:\User\user\AppData\Local\Arduino15.
The decoder is in C:\Users\user\AppData\Local\Arduino15\tools\EspExceptionDecoder\tool. The elf file is in C:\Users\user\AppData\Local\Temp\arduino_build_360380. One problem may be the decoder wants an .elf extension, but the elf file has an .ino extension. The ESP Exception Decoder window opens, but won't allow me to paste anything in there.

Here is some of the Arduino output (edited):

Thanks for any help!

I was able to paste the backtrace into the ESP Exception Decoder window by using CTRL+V in windows, but the decoder did nothing.

I got it to work! Maybe because I tidied up my files a bit, but also you have to be sure to include the word "Backtrace" like so:

Backtrace: 0x4008b2cd:0x3ffb1e50 ...

Perhaps the module is a WROOM instead of a WROVER?

5

It's an AI Thinker board and it's listed on the Arduino IDE.
