Cross-compile Linux kernel

Cross-compile Linux kernel 1. download linux kernel source code I'm using a linux-loongson-release-zb-kernel.tgz to decompress it to the/usr/src Directory: tar-xzvflinux-loongson-release-zb-kernel.tgz will generate linux -... cross-compile Linux kernel 1. download linux kernel source code I used is the linux-loongson-release-zb-kernel.tgz to decompress it to the/usr/src Directory: tar-xzvf linux-loongson-release-zb-kernel.tgz in this directory will generate linux-loongson-release directory www.2cto.com II. download the cross-compilation tool: http://dev.lemote.com/files/binary/toolchain/kernel/gcc-3.4.6-newbin.ls2f.tar.gz Decompress the package to the/opt directory. first, modify the/opt permission sudo chmod 766/opt tar-xzf gcc? 3.4.6? Newbin.ls2f.tar.gz-C/opt and then specify its PATH export PATH =/opt/gcc-3.4.6-newbin/bin: $ PATH in the loop variables to write it ~ /. Bashrc, easy to use multiple times to set executable permissions chmod + x/opt/gcc-3.4.6-newbin/bin-R www.2cto.com III. the kernel configuration is in the source code directory: cp arch/mips/configs/loongson3a_xxxx_config. note: currently, five loongson3a_dawning_config loongson3a_rs780e_config loongson3a_server_config configuration files are available under arch/mips/configs, and then make config. you will find that the default loongson3a_server_config configuration file has been. 4. compile the kernel www.2cto.com 1. local compilation directly make the completion of Kernel Compilation 2. cross-compilation In the root directory of the kernel source code, enter make ARCH = mips CROSS_COMPILE = mipsel-linux-or modify makefile. modify the makefile in the root directory and assign the following value to the ARCH variable: ARCH? = Mips assigned CROSS_COMPILE variable CROSS_COOMPILE? = Mipsel? Linux? Note: Before executing this step, make menuconfig to enter the configuration page and select Enable loadable module support. then, select 3 and 4, or 2 and 4 in the lower-level directories. after the modification, select Save an Alternate Configuration File to Save the modification.
