安装QorIQ-SDK-V2.0-20160527-yocto时，执行bitbake fsl-image-minimal之后打印如下，出现如下错误：

编译目的是得到t1042的交叉编译工具。

使用的操作系统为Ubuntu-16.04.2

请问是否需要更换操作系统或者是哪一步需要修正，希望可以得到指正，不胜感激

Use Ubuntu 14.04 (32-bit or 64-bit) for SDK 2.0 building.

Ubuntu 16 can be used for LSDK building.

Have a great day,

已解决

原因：由于yocto自带bitbake，因此在执行时，直接使用绝对路径，未将bitbake工具组添加至全局变量，因此在后续的执行中无法找到bitbake-woker工具组，导致执行失败。
