[yocto] building for ZYNQ ZC702 SoC

Wed Dec 12 07:32:03 PST 2012

Hi Elvis,

I could not find where the arm gcc was included in this build.
I was checking the build process and took the gcc.4.4.6 while building the
core-image-minimal.

Hence i wanted to confirm if the arm-gcc can be integrated and steps to do
it.
