I compiled BusyBox using E500v2 SDK2.0 and found this problem
Please install SOURCE ISO QorIQ-SDK-V2.0-SOURCE-20160527-yocto.iso and Cache ISO QorIQ-SDK-V2.0-PPCE500V2-CACHE-20160527-yocto.iso in the same path.
Then execute the following command to create the build project.
$ source ./fsl-setup-env -m c293pcie
Then execute "bitbake busybox", you will find busybox images in QorIQ-SDK-V2.0-20160527-yocto/build_c293pcie/tmp/work/ppce500v2-fsl-linux-gnuspe/busybox/images.
