Failed to connect to the debug stub

[Hufflepuff]

Hello everyone,

I’m trying to connect to my Raspberry Pi 4 via JTAG (Olimex) for debugging but I always get an error that it can’t connect to the debug stub. When I check the gdb stub log I don’t see an error appearing, so I don’t really know what might be the issue? Im currently using the VisualKernel Beta version I recently downloaded from your homepage. Where do I find the entry to check if GDB is enabled, since in another post in your forum you mentioned that this needed to be checked. I also use a newer (I think) openocd version, since the given one seemed to have a hassle with the Olimex FTDI driver.

This is the gdb stub log I get:

Thanks for helping!

Hi,

If OpenOCD generally doesn’t work with your hardware, running it with VisualGDB/VisualKernel won’t automatically resolve the OpenOCD issues. If this is the case, please consider asking in the OpenOCD or Raspberry Pi community.

If you can get OpenOCD/gdb working when you launch it manually, we can gladly help you configure VisualGDB/VisualKernel to use this setup for debugging.

Hi,

Well it does work when I call it manually, this is why I switched the openocd.exe files, because it worked with that one.

Thanks

If you are able to connect (and successfully use) gdb to OpenOCD when you run it manually, please share the following:

• The exact command lines from OpenOCD and GDB from the manual debug session that works.
• The OpenOCD and GDB command lines shown by VisualGDB/VisualKernel. You can find the OpenOCD command line in OpenOCD window in Visual Studio during a debug session. The GDB command line is shown in the GDB session window.
• A screenshot of the exact error message you get with VisualGDB/VisualKernel.
