#htc-linux channel... It's different from the PPCG one. But most people don't follow it because if you don't understand linux, it's mostly greek
Here's an example conversation from the channel:
makkonen: I don't think the others get used very often if ever. but better to have and not need them than vice-versa, I guess
Markinus: NetRipper: Is on your device too, that the values e.g. from GPIOs 0xa900000 are changing after a write every time to 0x1c860054?
Markinus: like this
Markinus: pd 0xA9000020 0x8
Markinus: 1c860054 1c860054
Markinus: pd 0xA9000020 0x8
Markinus: 00000003 00000002
Markinus: pd 0xA9000020 0x8
Markinus: 1c860054 1c860054
eval-:makkonen: makes sense. the unused .ko aren't sitting in ram right?
makkonen: right
NetRipper: Markinus, whats at +0x20?
Markinus: NetRipper: this sould be GPIO1 config
