Since the 3.12-rc5 kernel does not work I decided to give the 3.8 kernel a try. The issue with this one is that the linux-ti-staging_3.8.bb recipe explicitly sets KERNEL_IMAGETYPE="uImage". However, the u-boot environment has now moved on to using zImage which consequently means u-boot will not find the kernel file.
I do not know why KERNEL_IMAGETYPE = "uImage" was hacked into the linux-ti-staging_3.8.bb recipe but whoever did it did not think about u-boot. Does zImage not work with 3.8? I did not try it but it should normally have no effect. Since there is no dependency of the u-boot recipes on the kernel image types changes to the kernel image type for newer versions of the kernel then automatically means that it must be changed for the previous versions too. I mocked around with the u-boot environment and booted the 3.8 uImage kernel. To my surprise the 3.8 kernel from the TI staging repository fails with the exact same problem and stops booting with a kernel not syncing message during the init calls. Apparently a patch must have been applied to the kernel repo that breaks it. It has nothing possibly to do with the build system. I would appreciate any hints to get this kernel built and boot on the board.
