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. -- Denys On Mon, Oct 21, 2013 at 10:42:35AM -0700, Rudolf Streif wrote: > Since the 3.12-rc5 kernel does not work I decided to give the 3.8 kernel a > try.
