Again about the Raspberry PI Pico support

Raspberry decided to misuse the ARM debug specification and made his device multidrop to access the different cores on the same chip instead of different DAP-AP's. The current firmware of the STlink's doesn't support (or we don't know the exact USB API call) multidrop so we can't use STlink's with these Raspberry Pi MCU's. And because STlink is currently the only supported interface for EBlink, EBlink can't support Pico's.

So, if you want to use a Pico you have to switch to a different probe (e.g. another Pi Pico) and use a GDB server (e.g. OpenOCD) which will support that particular probe.

For now ,I don't gone put a lot of effort in this. I'm not so thrilled about these MCU's and I think it will mostly find his way in the hobby sector but I personally won't use them.
