45 # to program the compulab NAND flash, the following scheme is suggested. Create
46 # a small rootfs that can fit in NOR flash using the following config:
48 # - uclibc (set ANGSTROM_MODE = "uclibc" in local.conf)
49 # - angstrom-minimal-image-with-mtd-utils bitbake target
50 # - put the following in your local.conf
51 # - IMAGE_FSTYPES = "jffs2 tar cpio.gz"
52 # now, when you build the image, a cpio.gz will be generated
53 # that can be used as an initramfs. You can boot into this image and then
54 # program the main rootfs jffs2 image in NAND flash using mtd-utils
55 # you can select booting the initramfs, or the main nand rootfs by using
56 # the "ramdisk on", or "ramdisk off" commands in the bootloader
