Re: AM335x EVM and core-image-sato

Rudi,

As we discussed earlier today, let my send you my binaries for the kernel and 
u-boot to try on your board. I just wanted to ask you about the toolchain that 
you used to build yours. In our builds we use Linaro gcc-4.7 hardfp toolchain 
and I vaguely remember hearing about some problems with the recent gcc-4.8 
toolchain from oe-core... I'm wondering if you are having the same issue.
