Das U-Boot
当前版本
Das U-Boot (或只是“U-Boot的”的简称)是开源固件的嵌入式Power架构 ®,ARM,MIPS,x86和其他处理器。U-Boot项目由DENX托管,您还可以在其中找到项目主页: http://www.denx.de/wiki/U-Boot/
可以从DENX "git "存储库中检索当前版本的U-Boot源代码。
您可以在 http://git.denx.de/ 浏览 "git"存储库。
可以通过git,HTTP和rsync协议访问这些树。例如,您可以使用以下命令之一来创建其中一个源树的本地克隆:
git clone git://git.denx.de/u-boot.git u-boot/ git clone http://git.denx.de/u-boot.git u-boot/ git clone rsync://git.denx.de/u-boot.git u-boot/
也可以通过FTP获得U-Boot的正式版本 。压缩tar档案可以从目录 ftp://ftp.denx.de/pub/u-boot/ 下载。
