Prepare ENV settings for sheevaplugs to be OpenWRT ready.
+----------+ | UBOOT | >> 896 Kb (7x128) = uboot +----------+ | ENV | >> 128 Kb = uboot_env +----------+ | ROOT(FS) | >> 511 Mb @ 1 Mb = root -> rootfs (ubifs) +----------+
With (CC) TRUNK OpenWRT build (QUICK HOWTO) :
<INTERRUPT> Marvell>> nand erase.part root Marvell>> ubi part root Marvell>> ubi remove rootfs Marvell>> ubi create rootfs Marvell>> usb reset Marvell>> fatload usb 0:1 0x800000 sheevaplug/openwrt/openwrt-kirkwood-sheevaplug-rootfs.ubifs Marvell>> ubi write 0x800000 rootfs ${filesize} Marvell>> reset
Changes in v3 - Supress image partition (unused)
Change in v2 - Define new NAND partition mapping
