for building this outdates build you might need to use older gcc:

sudo ln -sf /usr/bin/gcc-4.1 /usr/bin/gcc
gcc -v
....
gcc version 4.1.3 20080623 (prerelease) (Ubuntu 4.1.2-24ubuntu1)

is original build fails

if kernel fails at usb-gadget.c

Creating 3 MTD partitions on "gumstix-flash":

0x000001f00000-0x000002000000 : "Kernel"

!! compute padding side from FLASHsize - uboot = rootfs (HEX) - use gcacl ;)

http://docwiki.gumstix.org/index.php/Replacing_the_filesystem_image:

U-Boot (mtd0) - 256K : 262144 Bytes.
Kernel (mtd2) - 1M : 1048576 Bytes.
Padding size is FlashTotal - Kernel - U-Boot.

Basic / Connex Standard (4MB) : 2883584 Bytes = 0x2C0000.
XM Series (16MB Flash) : 15466496 Bytes = 0xEC0000.
Verdex XL6P (32MB Flash) : 32243712 Bytes = 0x1EC0000.

kernel must be ⇐ 1024kb (gzip might help a bit)

gzip -9 linux.bin
mkimage -A arm -O linux -T kernel -C gzip -a a0008000 -e a0008000 -n "oe-koala/verdex" -d zuImage-2.6.29.4-k0a1a-r3.gz zuImage-2.6.29.4-k0a1a-r3.bin
