Up to my understanding of the patches, the board shouldn't be very different from the original imx28evk so it probably may be supported and I may just have to reassign some pins and port the display patches. > - compare both kernel sources to see the changes done by the manufactor Ok, going back to re-read my books. Anyway, which kernel would you suggest considering the board doesn't look that different from the original imx28evk? > To be honest, I would start at U-Boot and not the kernel as it is > easier to hack and also allow for you to learn more about the board > specifics. Crossing fingers I may not have to learn how uboot works right now. thanks -- Ivan Sergio Borgonovo http://www.webthatworks.it
