No, I think there is no ecc/nand issue - it is just that the 2.6 kernel is too big for the partition and/or only partially copied to flash. Therefore the attempt to load but CRC fails. > The dev/mtd1 contain the binary content from the uImage.

Like that lfn-lsh-Ctrl copies the uImage to /dev/mtd1. I don't know if lsh+lfn+F1 works. > For kernel 2.6 we need to copy uImage manually with, cat uImage /dev/mtd1, > but first any nand ecc issues need to be resolved. good luck with JTAG setup. The reason may be that the 2.6 kernel is bigger and the automatic mode of U-Boot doesn't copy it completely. best regards, Nikolaus > > Some other links here: > http://trendtac.hyves.nl/forum/3469897/Fg01/Changing_boot_time_splash_screen/ > http://projects.kwaak.net/twiki/bin/view/Epc700/CompilingAKernel > http://projects.kwaak.net/twiki/bin/view/Epc700/KernelOfTheWeek > http://www.liliputing.com/tag/3k-razorbook-400 > http://www.littlelinuxlaptop.com/ > http://linuxlaptopforum.ark2webdesign.co.uk/index.php/board,27.0.html > > Grt Ruben. > _______________________________________________ > Mipsbook-devel mailing list > Mipsbook-devel@linuxtogo.org > http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/mipsbook-devel
