Debugging not hitting breakpoints #1392

Open aaron-neal opened 2 weeks ago

aaron-neal commented 2 weeks ago

I am trying to debug an ESP32-S2 board. I have succesfully connected the ESP-PROG board and can perfectly program the ESP32 from VS Code over ESP-PROG.

When i press debug, everything seems to work fine, except no breakpoints get hit in VS Code, it seems as if the debugger connects, but doesn't attach to VScode.

platformio.ini

debug_tool = esp-prog
upload_protocol = esp-prog
debug_init_break = tbreak setup

However, it appears the code isn't halted (watchdog LED is flashing) and no breakpoints are hit, including at setup.

Any help greatly appreciated.

Hi @aaron-neal, does it work if you remove the debug_init_break option?

aaron-neal commented 2 weeks ago

Hi @valeros, thanks for getting back to me. I will have to check later today, I did however notice the "2 locations" for the setup function so I renamed one of the functions in a library to see if this was the issue, but still did not work.

I also span up a linux VM to test and I had the same issue as on my Windows install.

I haven't tried with a simple blink sketch yet, but plan to do that as well.
