If this is indeed the wrong place (and even if it isn't!), please feel free to point me to a better forum for arm/omap specific kernel discussions. My questions are: 1. What is a good place to read up on how to write board files and drivers for OMAP3/4 based boards? The documentation I have found is scarce and often outdated. 2. A specific problem I have is with DSS/FB/LCD panel/the like. We have an old board file for v2.6.32 TI PSP. Despite doing what appears to be equivalent to what the old board file does, there is nothing shown on the LCD (nor DVI, VGA, TV-out, ....). What could have changed between TI's 2.6.32 and 3.0-omap that causes, for instance an LCD panel, to stay blank in the latter but not in the former. While an answer would be very appreciated, even better would be to get hints on how to learn to figure out the answer to #2 by myself... feeling that will be a handy skill... :-) Thank you, Arpad -- http://www.fastmail.fm - The professional email service
