JTAG Eclipse issues. Cmd prompt maybe?

Postby rfleming » Mon Jul 08, 2019 2:43 am

I am having an issue with eclipse when trying to debug. it keep showing the error "Could not determine GDB version using command: xtensa-esp32-elf-gdb --version". I immediately thought this was a pathing issue.

I tested everything with in CLI with mingw32.exe and it all works fine. Knowing that I had this issue, I tried several things, adding xtensa itself to windows environmental variables PATH, adding the IDF_PATH there too. None of these seemed to fix the issue. Eventually I opened up Windows Cmd Prompt, navigating into the folder directly and running the command I get no output. If I check the error code I got "-1073741819" (or 0xC000 0005).

However, the app appears to work fine in mingw32.exe and in "bash (MINGW64 - installed with git)" to give:

Code: Select all

Ryan@DESKTOP-BEAST MINGW64 /c/msys32/opt/xtensa-esp32-elf/bin
$ xtensa-esp32-elf-gdb.exe --version

I am thinking that its because of the apps issue with cmd that my eclipse is not working, but I am up for ideas.

I downloaded the lastest minw32 installation as suggested by the wiki from their link supplied.

Windows Version:
Microsoft Windows (Pro) [Version 10.0.17763.557]
Version: Photon Release (4.8.0)
Build id: 20180619-1200
MinW32 Version:
gcc (GCC) 7.4.0 (if this is how I get the version...stackoverflow seems to think so)

I have the same problem. "Could not determine GDB version using command: xtensa-esp32-elf-gdb --version"
I have just installed
Eclipse IDE for C/C++ Developers
Version: 2019-06 (4.12.0)
Build id: 20190614-1200
Updated it. Set up according the Expresiff manual.
I have also found the discussed earlier bug ;; in the PATH. Changed ;; with ;

Still I have "Could not determine GDB version using command: xtensa-esp32-elf-gdb --version".

Looks like this known issue was not fixced in Eclipse.
Any ideas how to start Debug seccion in Eclipse.
Best Regards
Sergei Nikulin

I faced the same problem.

When I installed the ESP tools plugin, the following path was added to the Window->Preferences->C/C++/Build/Environment PATH variable.


So I assume this is where the GDB launcher will locate the xtensa-esp32-elf-gdb.exe executable. So I tried to open a Windows CMD command window in the same location and execute "xtensa-esp32-elf-gdb.exe --version". Here there is no output on the terminal!!

I noticed that I also have a different tools location for the xtensa-esp32-elf-gdb.exe file:

If I try the same experiment from this location I do get a valid version output string on the terminal. So in the debug configuration under the debugger tab, for the GDB Command I selected Browse and selected the xtensa-esp32-elf-gdb.exe from the 2nd location above that seemed to work with the --version option.

Now it works!!

xtensa-esp32-elf version: esp32-2019r1-8.2.0 is having an issue in Windows, and this got fixed with the esp32-2019r2.

Please try this. Here is the link to download
