Re: Problem: Setting up JTAG debugger for ESP32
However, the gdbinit file in home\khoil has exact content as the one in D:\esp32\workspace\scan. So even if I remove the one in "khoil" folder, it probably wont fix the problem with gdb connection, right?
Thanks,
Thanks,

Re: Problem: Setting up JTAG debugger for ESP32
I think you are right, I think it tried to run the .gdbinit in .\home\khoil, eventhough my .gdbinit file I want it to run is in D:\esp32\scan\ So what is the best way for me to fix this?

Re: Problem: Setting up JTAG debugger for ESP32
Hi esp_igrr, I tried both of your methods and the results are the same. The problem is that gdb does not prompt me to write "-x .gdbinit." xtensa-esp32-elf-gdb build/scan.elf GNU gdb (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a5) 7.10 Copyright (C) 2015 Free Software Foundation, Inc.
