Error getting started debugging

Postby Andrew12345 » Wed Aug 21, 2019 7:14 pm

Hi,

I'm trying to follow the debugging example here: https://docs.espressif.com/projects/esp ... ugger.html

I'm using a segger J-Link. I don't think it makes a difference, but I'm using this ESP32 module: https://www.shenzhen2u.com/NodeMCU-32S

I loaded the example blink binary (only change in blink IO pin number), and the LED blinks just fine. I then ran

Code: Select all

openocd -f interface/jlink.cfg -f board/esp-wroom-32.cfg -l errorlog.txt
In another terminal window, I ran

Code: Select all

xtensa-esp32-elf-gdb build/blink.elf -x gdbinit
, and get output:

Code: Select all

Any help getting debugging to work would be appreciated.

Thank you!
