GDB stub for ESP8266 + FT4232

[julieninnovel]

Hello,

I’m using Visual GDB and GDB stub to program an ESP8266.

It’s working fine with my demo board and an USB <-> serial converter.

Now, I’m using my own board with 2 ESP8266 and I’m using an FT4232 to program and debug it.

The FT4232 is an USB <=> 4x serial converter. It’s the best for me because I have 2 ESP8266 with each one have a full serial link and an other one for debug printf.

My problem is that Visual GDB + GDB stub can’t program an ESP.

The FT4232 make me 4 COM PORT on Windows.

COM1 : program ESP 1

COM2 : debug ESP 1

COM3 : program ESP 2

COM4 : debug ESP 2

Each time I try to debug ESP 1 with COM2 (printf) and program with COM1, GDB say that COM2 is already open (of course, I try to catch all printf…) but the project properties are configured to program with COM1.

It’s the same for the  second ESP.

And if I don’t try to catch the printf (closing the COM2), GDB don’t find the module.

I’m really need to use an FT4232, how can I do this working ?

Thanks for your help

Hi,

Perhaps you have configured the VisualGDB’s raw terminal to open COM2? Either way, please try searching the .vgdbsettings file for any mentions of COM2. If none are found, please attach a screenshot of the error message you get and we will try to suggest you which setting could be affecting it.

Hi,

You’re right ! something was wrong in the vgdbsettings file.

I’ve create a new project and now it’s working fine.

Thanks for your help.
