To make a long story short: those devices expose a slightly tweaked interface to talk with the eInk controller, and I'd like to make sure we're doing it right in KOReader.
Right now, since no-one has come at us with pitchforks, current FW appear to still handle the older interface, but this may not hold true forever (although, given Kobo's track record, I doubt it will actually change, but, no matter).
The code is already written, it's just disabled until I have more details to make sure it's correct. That's where you come in!
You basically just need shell access to your device (be it telnet or SSH) *under Nickel*.
You don't necessarily need a deep understanding of the *nix CLI, but, of course, that's always a plus
.
If that's you, the gory details are explained in
the relevant KOReader issue.
Thanks!
