I've connected the QSPI pins for the flash on 0.2, is this something that should be added to the pin defs?
|

I think we will have to get a v0.2 board to Joel to make this a real thing. Possibly have both v0.1 or v0.2 board definitions. Given v0.1 boards are so few, the main definition can be the v0.2 one. |
|
Agreed, once we have some v0.2 boards we can decide how to support them. I wanted to submit this definition so we didn't have people duplicating the work of describing the pin layouts. |

What's going on with the LEDs here? If there's one RGB LED then there should be just an RGB LED resource.

"Semantic alias" generally means that there is some semantics beyond the numeric index, e.g. button_up would be one.

This is resource is missing the connector specification.

Thanks for the review @whitequark. I have learnt a bit more about nmigen and fixed a bunch of things; I'll rework the patch and try again. |
