We switched back to gcc-4.5 by pulling into our layer what meta-oe has thrown out of their toolchain-layer and fixing up a minor issue with the binutils GOLD linker. Right now we're using everything from Angstrom _except_ gcc-4.7. This is because ti81xx-psp-2.6.37 will not run out of the box when built with this version of gcc. Using latest Angstrom w/ gcc-4.5 from our own layer is just an intermediate step. It is necessary so we remain with a working platform. > and also be > ready to experience some bugs as well yes -mno-unaligned-access is > needed for kernel > in some cases but eventually I think new kernel should be able to handle them This is the next step. Now that we are on latest Angstrom (and, w/ gcc-4.5, can build firmware that boots) let's look into that gcc-4.7 issue. If it's really just a missing flag then we should be on 4.7 in no time. I would remain skeptical, though, since TI's kernel fork for DaVinci, ti81xx-psp-2.6.37, is very old and lacks of code quality.
