--- Quote Start --- You should do it in two steps. First, with normal initramfs, and no kernel command line. Edit drivers/mtd/maps/altera.c , to the offset and size of your cfi flash. Remove unused mtd parts. Rebuild zImage, and check if mtd is detected correctly. If mtdblock0 is correct, then try mount it as jffs2, copy the rootfs. And then reboot again, to verify if all the data is correct. If all work without problems, then do the step2, rootfs to your mtd.[/b] --- Quote End --- hi hippo i have modified the driver in /mtd/maps/altera.c and canceled some options in the kernel munuconfig, then has removed some apps in ~/rootfs/bin dir and rebuilt kernel finally..... my booting info as following : uClinux/Nios II Altera Nios II support © 2004 Microtronix Datacom Ltd.
