Can you give a quick example where this is useful? (Not a full example to be added to the repo, just a quick code snipped showing the use case.)

There are a lot of i2c related changes in https://github.com/rp-rs/rp-hal/pull/747. That's why I didn't touch i2c in https://github.com/rp-rs/rp-hal/pull/753. Please coordinate with @ithinuel.

Unfortunately, the necessary settings for using an external clock on the XIN pin are not well documented. There's already a ticket open about that: https://github.com/raspberrypi/pico-feedback/issues/322 Perhaps just try to disable...

If that's really the case, you could build your own boot2 loader with a reduced flash speed. To do that, you'd need to set a larger divider in https://github.com/rp-rs/rp2040-boot2/blob/main/build.rs#L36 and...

According to this forum thread, the external oscillator should work without special configuration: https://forums.raspberrypi.com/viewtopic.php?t=357622 And then, when using the XOSC, the startup code does wait for the oscillator to become...

(I saved some experimental code to https://github.com/jannic/rp-hal/commits/issue-756/)

I didn't work on it because nobody came up with an actual use case. If it helps you to implement SWD I can update the branch and make it a...
