GDB Debugger

I have read that one example of Visual Micro GDB integration is available for Arduino Zero!
That is the only board supported?
What about ESP8266 family?
I know that a GDBstub is available for all ESP8266!

I look forward to try to use a GDB debugger on ESP 8266!

Thanks

Yes it can do all but zero was first test because it was easy.

I don't have any info about how to configure and run gdb for esp8266. 

If you find links to examples I can take a look.

Thanks

Have a look to this link:
https://github.com/espressif/esp-gdbstub

I have tested myself the GDBstub using Visual GDB and it works!

If not to complex I can do some test myself. Undecided....just give me  some guidelines!

Thanks that is useful. I looked yesterday and it looks like to can work well.

But the thing I am unclear about is how to connect pc to esp for debug.

I notice some mention of usb serial in your example. Did you use serial or connect a JTAG adapter?

It's a serial GDBstub: so is normally connected through the usb port (or can be redirected to TCP IP). No special hw is required!

Ok can see that now.

It needs to have an MI facility (Machine Interface). It might work but it would be best of esp8266 installed the built gdb.exe with the tool chain.

If you have some ready to go files that would be great and I can try them but haven't got the time to build and research this right now.

I know Microsoft are also working to improve the underlying debug tool that I am using. So the job might get easier over the next few months.

With the Zero the gdb and scripts are installed with the tool chain. So all I had to do was alter some compile settings slightly.
