But when I use external dram as main ram, ethernet does not work :). Although my eCos work with K70 but it does not work with other boards & many hard-code for K70 only :). On the other hand, my main purpose when using Redboot for K70 is booting Linux kernel for it. So if you have done Redboot for K70 and it works well, please share it soon ^^! I think it better than mine. > > Ilija > Thanks & Regards, Linh Nguyen -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
