I am pretty new to ESP32 platform and I am currently working of another person's development who have completely depended on the UART to debug. I prefer if I am able to do inline debugging. I am hoping someone can point me on my mistake here to get this working.
I followed the instructions as per https://mcuoneclipse.com/2019/09/22/ecl ... r-j-link/ .
My OpenOCD is version: v0.10.0-esp32-20210401
My GDB is version GNU gdb (crosstool-NG esp-2021r1) 8.1.0.20180627-git
The problem occurs when while running the OpenOCD, the GDB hardware debugging fails.
The error occurs,when I start the xtensa-esp32-elf-gdb -x gdbinit build/gateway.elf:
The gdbinit file look like this:
Code: Select all
target remote :3333
set remote hardware-watchpoint-limit 2
mon reset halt
flushregs
htb app_main
c
Code: Select all
