Tiny4412_android4.1.2_gen-ing.sh出错

求解答
请问 gen-ing.sh最后出现./gen-img.sh: line 30: mkimage: command not found
但源代码根目录下有sysetem.img和4个usedate文件。这样算编译完成吗？
源代码文件是光盘自带的 文件名为：android-4.1.2-fs-20141114.tar.qz
Log如下：

./gen-img.sh: line 30: mkimage: command not found
corey@ubuntu:~/friendlyarm/android-4.1.2$

生成 ramdisk-u.img 时需要用到 mkimage
建议仔细看手册，应该是需要安装一些工具，如果找不到，通常开源的 uboot 里可以编译获得这个工具

哦 谢谢
