New reTerminal, powers up with blank screen

Oof, new user also hitting this (and more than a bit disappointed with seeed…). I’m getting the asm/types.h include errors and don’t see a way around it - the callouts to 32-bit OS’ throw me as it’s an aarch64 chip with an aarch64 kernel - are some reTerminal devices 32-bit, or are people just putting a 32-bit OS on them? Since there’s been no updates to the wiki or posts from Seeed am I guessing right that the reTerminal is known-broken-and-still-sold-anyway?
