gdb to vba

[wjakobczyk]

I'm trying to connect to VBA with gdb and get errors:
(gdb) target remote localhost:55555
Remote debugging using localhost:55555
Ignoring packet error, continuing...
warning: unrecognized item "timeout" in "qSupported" response
Ignoring packet error, continuing...
Remote replied unexpectedly to 'vMustReplyEmpty': timeout

Latest devkitpro and arm-none-eabi-gdb.exe there, VisualBoyAdvance-1.8.0-511.
Any clues?

Or what's other best method for source-level debugging of GBA code these days?
No$gba debugging does not work me either, getting "elf invalid form" when loading my simple elf file there...

VBA gdb connection hasn't worked in a very long time.

mGBA has a stub that works.
