Through the repo, there are various naming conventions, and led_n seems one of them.
Curious about what this is meant to be.

Well at least I use _n to mean it's active low.

This makes more sense to me that way too. Thank you for clarifying!
What a carefully crafted board support file! Instructive for myself...

@Icenowy: We can probably merge now that the board seems to be available. Thanks a lot! |

Well this PR targets ES board with ES chip. Maybe further change will be needed for final product board, I wonder whether Sipeed people want to do this. |
Tagged RFC now because the board (and even the chip on my board) is still at ES stage.
