Using gdb and an 'extended-remote' target

[sir-wombat]

Hello,

I'm trying to set up a very particular nvim-dap + gdb configuration, and I'm unsure, if what I'm trying to do is even possible:

I have a working dap configuration, using gdb 14.1 for local C programs (compiled and running on the same machine as nvim), which works completely as I would like it to.

The trouble is my black magic probe (a hardware debugger from here: https://black-magic.org/ ). When I run gdb manually, it works exactly as I expect it to, but I don't know how to set it up with nvim-dap. I'd expect this to be a use case for the attach-request, but that seems to only work with "remote" targets, not with "extended-remote" (as the black magic probe requires), at least if I understand the gdb documentation correctly: https://sourceware.org/gdb/current/onlinedocs/gdb#Debugger-Adapter-Protocol

So is this simply impossible (for now, until gdb improves), or am I maybe just holding it wrong?

Best Regards,
Wombat
