Hammer How to build Kernel
Here is how to build a custom kernel:
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.
Some common values for .size are:
2 MB = 0x1F4000 3 MB = 0x5DC000 4 MB = 0x3E8000 6 MB = 0x5DC000 8 MB = 0x7D0000 10 MB = 0x9C4000 12 MB = 0xBB8000
tar xzf linux-2.6.22.tar.gz gunzip -c Hammer-linux-2.6.22-09122007.diff.gz | patch -p0 cd linux-2.6.22 Edit linux-<version>/arch/arm/mach-s3c2410/mach-tct_hammer.c to change .size if needed. cp hammer-config .config make oldconfig make zImage
The kernel can be found in arch/arm/boot/zImage
