Intrestingly, as Hunyue mentioned, NO errors. b) Patch from Paul (5c6cd5d71bdb1a8536238c7812f1dbd6a68bc542), enables LCD on 2430SDP with LCD backlight and all.. This is the first patch that makes 2430SDP LCD work and the error that i started this chain with exists! c) all intermediate patches between (a) and (b) including the following: Richard W (bbe8d2b1654809c39be2e9ecc91dd5632006a2cb) Tony (517928578afaea422975fd8216242fdd067b56a2) Tony(dd1d9a62f7cd60b544013eb429d6a3137617f0b2) all retain the same state as I mentioned in (a). Not much useful information except that my guess is FB LCD is broken on 2430SDP as of date and it is possibly broken from the time it is enabled.. Since i do see Tony punching in a bunch every weekend, did Hunyue test with the git latest once Tony finished pushing all patches? - esp since May 25th is the time when the major clock/prcm framework patches from Paul W went into git. > On Sunday 08 July 2007 16:01, Paul Walmsley wrote: > >> You mentioned earlier that this code formerly worked for you before the >> PRCM changes.

I did try this, and i failed badly.. this is a topic of a seperate mail.. Regards, Nishanth Menon
