Configure the cross-compiling environment in Linux, and configure the compiling kernel and uboot installation.

This article is an experiment on the h9200e Development Board. In Linux, copy the fedora cookbook to/root.
1. Install the Cross Compiler
Log On As a Super User
[Root @ hostname] # bunzip2 cross-2.95.3.tar.bz2; unzip
[Root @ hostname] # tar xvf cross-2.95.3.tar
Put the obtained 2.95.3 folder under/usr/local/arm. Remember to use this path later.
2. Configure the kernel
Take the minimum h9200e configuration as an example.
Iii. Compile the kernel
Decompress the kernel source code package and edit makefile.
Set cross_compile: = [absolute path of the compiler]; this absolute path is the path put in the above 2.95.3.
Enter the kernel folder and execute the following command
[Root @ hostname] # Make clean
[Root @ hostname] # Make Dep
[Root @ hostname] # Make
[Root @ hostname] # [absolute path of the compiler]/bin/ARM-Linux-objcopy-O Binary-s vmlinux Linux. Bin; the absolute path of the compiler is also the path mentioned above
[Root @ hostname] # gzip Linux. Bin
The following is important, mainly the installation of U-boot, which is not clear in the h9200 manual.
[Root @ hostname] # tar xzvf u-boot-1.0.0.tar.gz; unzip U-boot
[Root @ hostname] # cd u-boot-1.0.0
[Root @ hostname] # Make distclean
[Root @ hostname] # Make at91rm9200dk_config
[Root @ hostname] # Make all
Then create a uboot folder under/usr/local to copy all the files under the u-boot-1.0.0 to the uboot
[Root @ hostname] # [uboot absolute path]/tools/mkimage-A arm-O Linux-C gzip-A 0x20008000-E 0x20008000-D linux.bin.gz uimage; the absolute path here is/usr/local/uboot.
Okay, the kernel has been compiled. You can go down to the board and check it !!!
