注：本文基于u-boot.2016.03版本
1、 安装编译器
运行.sh脚本后会安装到 /opt目录下
/fsl-arm-yocto-bsp/build-fb/tmp/deploy/sdk/fsl-imx-fb-glibc-x86_64-meta-toolchain-cortexa9hf-neon-toolchain-4.1.15-2.1.0.sh
hedy@ubuntu:~/u-boot$ ls /opt/fsl-imx-fb/4.1.15-2.1.0/
environment-setup-cortexa9hf-neon-poky-linux-gnueabi sysroots/
site-config-cortexa9hf-neon-poky-linux-gnueabi version-cortexa9hf-neon-poky-linux-gnueabi
新打开的终端需要:
source environment-setup-cortexa9hf-neon-poky-linux-gnueabi
来设置环境变量
2、指定u-boot输出目录
hedy@ubuntu:~/u-boot$ make O=./mx6qsabreauto_eimnor_config
make[1]: Entering directory `/home/hedy/u-boot/mx6qsabreauto_eimnor_config'
HOSTCC scripts/basic/fixdep
GEN ./Makefile
HOSTCC scripts/kconfig/conf.o
HOSTCC scripts/kconfig/zconf.tab.o
HOSTLD scripts/kconfig/conf
scripts/kconfig/conf --silentoldconfig Kconfig
***
*** Configuration file ".config" not found!
***
*** Please run some configurator (e.g. "make oldconfig" or
*** "make menuconfig" or "make xconfig").
***
make[3]: *** [silentoldconfig] Error 1
make[2]: *** [silentoldconfig] Error 2
make[1]: *** No rule to make target `include/config/auto.conf', needed by `include/config/uboot.release'. Stop.
make[1]: Leaving directory `/home/hedy/u-boot/mx6qsabreauto_eimnor_config'
make: *** [sub-make] Error 2
由于make mx6qsabreauto_eimnor_deconfig,的时候没有加 O=./mx6qsabreauto_eimnor_config
hedy@ubuntu:~/u-boot$ make O=./mx6qsabreauto_eimnor_config mx6qsabreauto_eimnor_deconfig
hedy@ubuntu:~/u-boot$ make O=./mx6qsabreauto_eimnor_config
此时编译输出到 **mx6qsabreauto_eimnor_config ** 目录.
3、make menuconfig 出错
hedy@ubuntu:~/u-boot$ make menuconfig
HOSTCC scripts/basic/fixdep
HOSTCC scripts/kconfig/mconf.o
In file included from scripts/kconfig/mconf.c:23:0:
scripts/kconfig/lxdialog/dialog.h:26:20: fatal error: curses.h: No such file or directory
#include CURSES_LOC
^
compilation terminated.
make[1]: *** [scripts/kconfig/mconf.o] Error 1
make: *** [menuconfig] Error 2
安装：
hedy@ubuntu:~/u-boot$ sudo apt-get install libncurses5-dev
