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