TinyFPGA AX2: Set internal oscillator as default

Open jreyesr opened this issue 4 years ago • 3 comments

NOTE: In draft mode and awaiting for upstream PR to be merged

This PR changes the TinyFPGA AX2 board to use the internal high-speed oscillator by default, since the board has no external clock and thus no default sync domain.

Notice: This PR is dependent on https://github.com/nmigen/nmigen/pull/575 being merged. Until then, it would cause an error since OSCH is not a valid resource on the TinyFPGA AX2 board.

FWIW, I checked out both this PR and nmigen/nmigen#575 locally. They both work fine when paired with some quality-of-life changes I intend to submit after this PR is merged.

@jreyesr There seems to be a bit of MachXO* activity in Amaranth as I type this. So it jogged my memory about this; would you be willing to mark this as ready to merge now that #575 was merged?

Hello @cr1901! Wow, it's been a while. Yes, this PR is ready to merge from my side, I just rebased the changes on top of current main. And many thanks for remembering this PR!
