1. 在vmware上装了Fedora 22， 因为似乎Fedora 22 是NXP验证过的平台。 =========================================== Yocto Project supports typical Linux distributions: Ubuntu, Fedora, CentOS, Debian, OpenSUSE, etc. More Linux distributions are continually being verified. This SDK has been verified on following Linux distributions: Ubuntu 14.04, CentOS-7.1.1503, Debian 8.2, Fedora 22 and OpenSUSE 13.2
========================================================================== 但是然并卵，Fedora22下bitbake fsl-image-core仍然会出现错误，在1/19日安装Fedora23，在1/20日提示安装perl-bignum下（详见3），问题解决，build完成。 2. 在使用过程中，竟然发现虚拟机一开始分配的空间不够。第一次在/fedora/root的LV下extend了60G，后来发现是/fedora/home的空间不够，后来又在/fedora/home下extend了60G。
使用命令： lvextend -l +15369 /dev/fedora/root (extend root volume) lvextend -l +15369 /dev/fedora/home (extend home volume)
具体使用方法可以参照此博客中的LVM扩容的两篇文章。
3. 值得记录的是，在Fedora23下竟然在安装“perl-bignum”这个东东后，bitbake fsl-image-core出现的错误（例如Function failed: do_configure ）都不再出现了。 错误信息有提示安装perl-bignum ERROR: The perl module 'bignum' was not found but this is required to build openssl.  Please install this module (often packaged as perl-bignum) and re-run bitbake.

开始安装perl-bignum [sudo] password for wireless: 
[root@localhost ~]# dnf install perl-bignum

Dependencies resolved.

4. build完成后在地址/build_ls1012ardb下发命令“bitbake -c cleansstate u-boot”后，会发现git（/home/wireless/nxp/QorIQ-SDK-V2.0-20160527-yocto/build_ls1012ardb/tmp/work/ls1012ardb-fsl-linux/u-boot-qoriq/2016.09+fslgit-r0/git）的文件夹会变空。
