There will be both compressed and uncompressed rootfs images in the buildroot/binaries/<project> directory. To do this, you have to set the size of the '''initramfs/initrd''' in the kernel. Find Block Devices in the kernel configuration and set the size to be just a little larger than your '''uncompressed''' initramfs/initrd. Only add a multiple of 1024 bytes.

 Here is how to build a custom kernel:
+NOTE: Kernel 2.6.29 seemed a little easier to build then 2.6.22 did, Check towards bottom for instructions.
 NOTE: If you are installing a custom rootfs, you may have to increase the size of the space in flash to hold the new rootfs image. You do this by editing the '''linux-<version>/arch/arm/mach-s3c2410/mach-tct_hammer.c''' file.  Find the '''.size''' string and change the value to be a little larger than your rootfs image is. The image size is in hex, so you will have to do a conversion to get the right value.
