Using GDB for online debugging ESP8266

[tomaszchacuk]

Hi,

For a couple of days, I've been struggling to configure debugging for ESP8266 running on Arduino and using PlatformIO. I managed to build a proper binary file with http://blog.squix.org/2016/04/esp8266-offline-debugging-with.html:

1. Added build_flags = -Og -ggdb -DDEBUG_ESP_PORT=Serial to platformio.ini 2.Downloaded full xtensa SDK as this provided for PIO does not include xtensa GDB Thanks to these steps I am able to offline debug - see lines numbers etc,but I cannot make it work with online debugging. Here is what I've done:
2. Added GDBStub.h include to my main class
3. Started GDB with firmware that has debugging symbols included(from step 1) to debug via COM - set ,baud rate to 115200 (the same as I use for normal state check via serial monitor - wifi messages etc.) .
4. I get no response - only timeouts etc
5. In the result, I would like to use CLion to insert breakpoints watches etc.

Can someone pint me what I'm missing ? I have 2 suspicions :

• Is including only GDBAtub.h enough or should I call gdb_init somewhere (its's not recognized as a function) or do anything more.
• Baud rate - should I use the same as the one set for serial communication messages (115200) ?

I am using Windows.

Hello

I have a similar problem, I tried to integrade GDB in my PlatformIO project using the ESP8266. It seems that I don't managed to add the full xtensa toolchain. As soon I call gdb_init, there are further files missing.. It would be nice if the needed GDB ressources (full xtensa-toolchain) would be already integrated in PlatformIO.
