ok. Agreed. Another thing just poped into my mind, ATM I have a DMA patch for devkit8000 on the ML: http://article.gmane.org/gmane.comp.boot-loaders.u-boot/109744 http://article.gmane.org/gmane.comp.boot-loaders.u-boot/112661 It speeds up the process of copying the u-boot/linux image. ATM this is in combination with HW ecc and I doubt that it will work seamlessly with SW-ecc, yet. However IMHO DMA in combination with SW-ecc could be nearly as fast as using HW-ecc. So maybe an adaption is worth a try? Regards Simon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
