我试着用不同的ARCH（x64，i386）和不同的工具链为我的beaglebone黑色交叉编译linux内核3.14。但他们都不能正确启动。它总是在为beaglebone黑色交叉编译linux内核
## Booting kernel from Legacy Image at 80007fc0 ...

停止我觉得我用的是不正确的工具链，所以我尝试使用工具链的TI StarsWares和Linaro的工具链。但它仍然不起作用。我也认为我需要使用32位ubuntu而不是我的Ubuntu 14.10（64位），但它仍然无法正常工作。
最后，我尝试编译一个示例c程序，并尝试在我的beaglebone上运行它。它说：
[email protected]:~\# ./test
-sh: ./test: No such file or directory
它似乎我使用不正确的工具链。
我尝试使用的内核配置文件：
git://github.com/beagleboard/kernel.git
，但它仍然停留在：
Starting kernel ...
我crosscompile工具链了。
我的内核编译命令是：
make ARCH=arm CROSS_COMPILE=/home/larry/develop/linaro-toolchain/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-

这花我要多少时间。任何人都可以帮助我？ 谢谢。
我想在你的桌面上安装Linux可以帮助：首先，你将学习Linux，其次，在Linux上交叉编译可能更容易。 – 2014-10-20 08:35:24
您可能没有交叉编译问题。从'0x80007fc0'启动似乎是Beaglebone的典型代表，但不是其他ARM板。尝试将uImage加载到0x80200000，将DTB加载到0x81200000，如[此处]所述（http://elinux.org/Building_BBB_Kernel）。这些地址必须在** bootcmd ** U-Boot环境变量中修改。 – sawdust 2014-10-20 19:16:56
*“我尝试编译一个示例c程序并尝试在我的beaglebone上运行...” - - 这种失败很可能是一个共享库问题。使用'-static' GCC编译/链接选项静态链接你的程序。 – sawdust 2014-10-20 19:26:29
