18 # NAND flash eraseblock size
19 # most of the older cm-x270 modules are populated with NAND flash
20 # that have 128KiB eraseblocks. Recently, a user encounted
21 # a device that has 16KiB eraseblocks. The following define
22 # can be overridden in local.conf if you have one of these devices.

28 # used by sysvinit_2 package, so rebuild this
29 # package if you change the SERIAL_CONSOLE setting
30 # the following is the port for the cm-x270 L module
31 # I think the W module would use ttyS0, but has
32 # not been tested. This can be overwritten in

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