Update to OpenOCD 0.12?

[rgrr]

Hello Earle,

don't want to bother you (I'm the one who filed issue #23)... but would it be possible to update to openocd 0.12?

The currently used openocd 0.11 has an issue with more recent CMSIS-DAP protocol, specific > 2.0.0 or anything after CMSIS 5.7.0 which is almost 3 years old.

Problem is, that openocd 0.11 cannot handle DAP_Info/Capabilities with two bytes and thus rejects connection. On the other hand pyocd requires a newer CMSIS-DAP version for its auto-detect feature.

With openocd 0.12 it's working of course:

Sorry, I don't think that's possible. We need to support Picoprobe which means we're stuck with the Raspberry Pi fork, rp2040 branch. That has not been updated to 0.12.

I think your best bet is to build/get a 0.12 binary and stuff it in place of the one from this package set. Since you don't use Picoprobe it should be fine there.

You could also open a raise in the RPI OpenOCD fork and see if they'd be willing to pull upstream.

Ok, I didn't think about that. I will check the possibilities ;-) I guess we can close this then.
