"mkimage" command not found - U-Boot images will not be built

/work/system/linux-3.4.20/arch/arm/boot/Makefile:89: recipe for target 'arch/arm/boot/uImage' failed

make[1]: *** [arch/arm/boot/uImage] Error 1

/work/system/linux-3.4.20/arch/arm/Makefile:281: recipe for target 'uImage' failed

我在网上搜了，用了

sudo apt-get install uboot-mkimage

但是，没安装成功

root@alan:/work/system/linux-3.4.20# sudo apt-get install uboot-mkimage

Package uboot-mkimage is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

However the following packages replace it:

  u-boot-tools:i386 u-boot-tools

E: Package 'uboot-mkimage' has no installation candidate

上面说了，安装 u-boot-tools  就可以了。

综上所述，解决方案：

sudo apt-get install u-boot-tools
