Hello everybody ! i'de really appreciate if somebody could help me solve this issue. I followed this tutorial to bitbake images for the mini2440 : http://www.developmentboard.net/index.php/company-news/openembedded-howto and so far i could get nothing to work, for instance u-boot wont run from the NAND flash, once i upload it and execute from RAM it runs but as soon as i write it to NAND and reboot its like it was never there, also i bitbaked a kernel for the mini but that doesn't seem to work either. Every time i try to burn the image with the default kernel and supervivi as a bootloader i always get a kernel panic, could not execute /linuxrc. By the way i have a mini with 256Mb NAND. I really appreciate guys, any help or clarification is welcome because i'm kinda lost here ^_^" and not to mention i got the mini to start off with embedded systems :) Best regards,
