kernel irst of all: cross compiler tools arm-linux-gcc - 3.4.1 3.4.1 Has been installed directly downloaded from the Internet source and patches
linux- linux - 2.6.21 2.6.21 .tar.bz2 . tar.bz2 2.6.21 2.6.21 -at91.patch. gz - at91.patch.gz
Second: extract the above documents
$ tar jxvf linux- $ Tar jxvf linux - 2.6.21 2.6.21 .tar.bz2 . tar.bz2
$ C p 2.6.21 -at91.patch. gz /linux-2.6.21
$ cd linux- 2.6.21
$ zcat 2.6.21 -at91.patch. gz | patch –p1
linux- Laws linux - 2.6.21 2.6.21 Makefile Contents of the document Makefile

CROSS_COMPILE
改成： With:
ARCH = arm
CROSS_COMPILE =/usr/local/ arm/ 3.4.1/ bin/arm-linux-
$ cp arch/arm/configs/ at91sam9261ek_ defconfig /.config
$ make clean
$ make zImage
UImage production of documents
$ / Usr / local / arm / 3.4.1 /bin/arm-linux- objcopy –O binary –S vmlinux linux.bin
$ gzip –v9 linux.bin
$./mkimage –A arm –O linux –T kernel –C gzip –a 0x20008000 –e 0x20008000 –d linux.bin.gz uImage
