[Closed] JTAG - Watchpoint, value unavailable
Posted: Mon Jun 11, 2018 2:00 pm
Hi,
I'm working on ESP32 WROOM and now using JTAG to flash and debug.
I manage to get it working but i can't get watchpoint working.
Here's the output on gdb :
I have the same problem using eclipse, where the value is written as unavailable.
I have the compiler setup for debug (-Og).
Here's my config files :
openocd config file:
gdbinit:
What am i missing ?
Thanks,
Tony
