Or you just looked at schematic and deduced this observation (as other people too)? Joerg already told us that RX51 schematic does not 100% match production N900 and e.g. there is missing UART3 pins... What we know that gpio 178 is *already* controlled and changed by production Nokia kernel running on production N900 devices (as I wrote in first email). -- Pali Rohár pali.rohar@xxxxxxxxx
