1、下载内核源代码,解压:https://github.com/altera-opensource/linux-socfpga/tree/socfpga-3.12
2、配置顶部的makefileARCH = arm
CROSS_COMPILE = arm-Linux-gnueabihf- (arm-gcc 目录)
# Architecture as present in compile.h
UTS_MACHINE := $(ARCH)
SRCARCH := $(ARCH)
2、配置Gcc:export CROSS_COMPILE= arm-linux-gnueabihf-
make ARCH=arm socfpga_defconfig
make ARCH=arm zImage LOADADDR=0x8000
