JZ2440学习总结3
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
使用FTP可直接登錄 linux虛擬機上，進行遠程操作
要是使用的是一期的視頻教程和老版本的UBUNTU進入需要使用
使用
tar xjf u-boot-1.1.6.tar.bz2 //解壓uboot文件使用

Makefile:416:*** mixed implicit and normal rules: deprecated syntax Makefile:1449:*** mixed implicit and normal rules: deprecated syntax這是因為使用 make 比 文件中的make 較新導致的，因此需要進行如下更改即可
對416行進行修改
將
更改為
%config: scripts_basic outputmakefile FORCE將1449行
/ %/: prepare scripts FORCE更改為
%/: prepare scripts FORCE若是在進行 make uImage指令之后出現
"mkimage" command not found - U-Boot images will not be built需要進行手動的 uboot工具安裝，安裝的命令如下：；
sudo apt-get install u-boot-tools然后在進行
make uImage總結
