Bundled OpenOCD does not handle CMSIS-DAPv2

[rgrr]

Hello Max,

I'm currently experimenting with CMSIS-DAPv2 for the picoprobe. During my experiments I found out, that the bundled (Windows) OpenOCD does not handle CMSIS-DAPv2.

Log should look like this:

But the bundled version shows:

...

...

Any chances to include an updated version which is fixed?

Sorry if this is the wrong place, but I have to admit that I do not understand where are the actual packet sources came from and you are the closest pointer...

The OpenOCD version comes from https://github.com/earlephilhower/pico-quick-toolchain/, can you ask there to activate the CMSIS-DAP compile options?
