--- 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.

If i'm right, you try create a partition on your flashrange which doesn't exist (from 8MB to 12,5MB). You have only 4 MB !?!
Nothing to worry about. You'll have to modify altera.c again, if you to remove this notification -> remove this entry in the partition structure. - Altera_Forum
hi Helmchen
thanks for your reply yor are right. because my flash only have 4MB that range is from 0x000000 to 0x400000 correctly,before it was my mistake .... <div class='quotetop'>QUOTE </div> --- Quote Start --- Altera NDK flash (AMD): Found 1 x16 devices at 0x0 in 8-bit bank Amd/Fujitsu Extended Query Table at 0x0040 number of CFI chips: 1 cfi_cmdset_0002: Disabling erase-suspend-program due to code brokenness. cmdlinepartlable parsing not available RedBoot partition parsing not available Using Altera NDK partition definition Creating 1 MTD partitions on "Altera NDK flash (AMD)": 0x00000000-0x00400000 : "romfs/jffs2"[/b] --- Quote End --- Is it important for red lines ? thx - Altera_Forum
