# a small rootfs that can fit in NOR flash using the following config:
# - Angstrom distro
-# - uclibc (set ANGSTROM_MODE = "uclibc" in local.conf)
+# - uclibc (set ANGSTROMLIBC = "uclibc" in local.conf)
# - angstrom-minimal-image-with-mtd-utils bitbake target

# - IMAGE_FSTYPES = "jffs2 tar cpio.gz"
