我試着用不同的ARCH（x64，i386）和不同的工具鏈爲我的beaglebone黑色交叉編譯linux內核3.14。但他們都不能正確啓動。它總是在爲beaglebone黑色交叉編譯linux內核
## Booting kernel from Legacy Image at 80007fc0 ...
Image Name: Linux-3.17.1+
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 6732680 Bytes = 6.4 MiB
Load Address: 80008000
Entry Point: 80008000
Verifying Checksum ... OK
## Flattened Device Tree blob at 80f80000
Booting using the fdt blob at 0x80f80000
XIP Kernel Image ... OK
OK
Using Device Tree in place at 80f80000, end 80f92df6
Starting kernel ...
停止我覺得我用的是不正確的工具鏈，所以我嘗試使用工具鏈的TI StarsWares和Linaro的工具鏈。但它仍然不起作用。我也認爲我需要使用32位ubuntu而不是我的Ubuntu 14.10（64位），但它仍然無法正常工作。
最後，我嘗試編譯一個示例c程序，並嘗試在我的beaglebone上運行它。它說：
[email protected]:~\# ./test
-sh: ./test: No such file or directory
它似乎我使用不正確的工具鏈。
我嘗試使用的內核配置文件：
git://github.com/beagleboard/kernel.git
，但它仍然停留在：
Starting kernel ...
我crosscompile工具鏈了。
我的內核編譯命令是：
make ARCH=arm CROSS_COMPILE=/home/larry/develop/linaro-toolchain/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-

這花我要多少時間。任何人都可以幫助我？ 謝謝。
我想在你的桌面上安裝Linux可以幫助：首先，你將學習Linux，其次，在Linux上交叉編譯可能更容易。 – 2014-10-20 08:35:24
您可能沒有交叉編譯問題。從'0x80007fc0'啓動似乎是Beaglebone的典型代表，但不是其他ARM板。嘗試將uImage加載到0x80200000，將DTB加載到0x81200000，如[此處]所述（http://elinux.org/Building_BBB_Kernel）。這些地址必須在** bootcmd ** U-Boot環境變量中修改。 – sawdust 2014-10-20 19:16:56
*「我嘗試編譯一個示例c程序並嘗試在我的beaglebone上運行...」 - - 這種失敗很可能是一個共享庫問題。使用'-static' GCC編譯/鏈接選項靜態鏈接你的程序。 – sawdust 2014-10-20 19:26:29
