参考：Linux 4.19.88 移植到imx280_buildroot280-CSDN博客
1.编译elftosb工具
$ cd imx280_zlg $ TopDir=`pwd`
修改imx280_zlg文件夹中的Makefile文件：
OUT_DIR := $(CURDIR)/OUT $(shell [ -d ${OUT_DIR} ] || mkdir -p ${OUT_DIR}) _cross_compile=$(shell cd cross_compile/bin/;pwd) _out_dir=$(shell cd $OUT_DIR;pwd) CC=${_cross_compile}/arm-none-eabi- .PHONY: bootloader kernel tools bootstream all: bootloader kernel @echo -e "\t\033[32m build success . \033[0m" bootloader: ${MAKE} -C bootloader/u-boot-2017.09/ ARCH=arm CROSS_COMPILE=${CC} O=${OUT_DIR}/uboot mx28evk_defconfig ${MAKE} -C bootloader/u-boot-2017.09/ ARCH=arm CROSS_COMPILE=${CC} O=${OUT_DIR}/uboot u-boot.sb -j8 cp bootloader/u-boot-2017.09/bootstream/uboot_ivt.bd ${OUT_DIR}/uboot/ cd ${OUT_DIR}/uboot; rm u-boot.sb;../tools/elftosb -f imx28 -c uboot_ivt.bd -o uboot.sb cd ${OUT_DIR}/uboot; ./tools/mxsboot sd uboot.sb uboot.sd # dd if= ${OUT_DIR}/uboot/uboot.sd of=/def/sdf1 #$(OUT_DIR)/tools/elftosb -f imx28 -c ${OUT_DIR}/uboot/uboot_ivt.bd -o ${OUT_DIR}/uboot/boot.sb kernel: make -C kernel/linux-4.19.88/ ARCH=arm CROSS_COMPILE=${CC} O=${OUT_DIR}/kernel mxs_defconfig make -C kernel/linux-4.19.88/ ARCH=arm CROSS_COMPILE=${CC} O=${OUT_DIR}/kernel -j8 tools: mkdir $(OUT_DIR)/tools make -C elftosb/ O=$(OUT_DIR)/tools/ rm $(OUT_DIR)/tools/*.o make -C imxtools/sbtools/ O=$(OUT_DIR)/tools/ rm $(OUT_DIR)/tools/*.o make -C imxtools/uuc/ O=$(OUT_DIR)/tools/ rm $(OUT_DIR)/tools/*.o strip $(OUT_DIR)/tools/* clean: rm OUT/ -rf指定编译结果的输出位置
export OUT_DIR=${TopDir}'/out'
指定默认编译器使用当前系统x86-x64的gnu gcc编译器编译
export CC=gcc
删除源码中：
dengxm2024@PC-202105142413:~/imx280_zlg$ rm -r -f elftosb/
下载源码：
cd ~ git clone https://github.com/eewiki/elftosb 复制源码到~/imx280_zlg
dengxm2024@PC-202105142413:~/imx280_zlg$ cp -r ../elftosb/
修改elftosb的makefile.rules.
“CC ?= gcc”修改为“CC := gcc”

编译：
make tools2.编译uboot
修改Makefile：
dengxm2024@PC-202105142413:~/imx280_zlg$ nano Makefile
修改编译器定义为：
CC=${_cross_compile}/arm-none-eabi-
编译uboot
make bootloader出现错误：
编译uboot出现下面错误 HOSTCC tools/pbl_crc32.o ../tools/mxsimage.c:18:10: fatal error: openssl/evp.h: No such file or directory 18 | #include <openssl/evp.h> | ^~~~~~~~~~~~~~~ compilation terminated.
编译器未能找到 OpenSSL 的头文件 evp.h。这通常意味着你的主机系统上没有安装 OpenSSL 开发库，或者编译环境没有正确配置来查找 OpenSSL 的头文件。
安装SSL库
sudo apt-get install libssl-dev3.编译内核：
make kernel出现错误：
HOSTCC scripts/kconfig/conf.o YACC scripts/kconfig/zconf.tab.c /bin/sh: 1: bison: not found make[3]: *** [scripts/Makefile.lib:196: scripts/kconfig/zconf.tab.c] Error 127 make[2]: *** [/home/dengxm2024/imx280_zlg/kernel/linux-4.19.88/Makefile:534: mxs_defconfig] Error 2 make[2]: Leaving directory '/home/dengxm2024/imx280_zlg/OUT/kernel' make[1]: *** [Makefile:146: sub-make] Error 2 make[1]: Leaving directory '/home/dengxm2024/imx280_zlg/kernel/linux-4.19.88' make: *** [Makefile:23: kernel] Error 2
bison（一个通用的 LL*(1) 文法解析器生成器）
下载安装依赖库：
sudo apt-get install bison出现错误：
LEX scripts/kconfig/zconf.lex.c
/bin/sh: 1: flex: not found
flex，一个用来生成词法分析器的工具，安装：
sudo apt-get install flex出现错误：
修改dtc代码
您可以手动修改dtc代码以避免多重定义问题。通常的方法是在dtc-lexer.l和dtc-parser.y文件中使用extern关键字来声明yylloc变量。具体步骤如下：
在scripts/dtc/dtc-lexer.l文件中，找到yylloc的声明（通常在文件的顶部）添加“extern” 并将其修改为：
extern YYLTYPE yylloc;
继续编译。
编译成功。
4.下载buildroot源码
tar -zxvf /mnt/d/imx280a_exe_folder/buildroot-2019.11.3.tar.gz -C ./
make freescale_imx28evk_defconfig
make menuconfig
错误：
dengxm2024@PC-202105142413:~/buildroot-2018.11.4$ make menuconfig
mkdir -p /home/dengxm2024/buildroot-2018.11.4/output/build/buildroot-config/lxdialog

make: *** [Makefile:901: /home/dengxm2024/buildroot-2018.11.4/output/build/buildroot-config/mconf] Error 2
根据提示安装依赖库：
sudo apt install libncurses-dev
