Marek Vasut insists I report this to the list, so here goes; Compiling a U-Boot for i.MX51 here (for the Efika MX) basically doesn't operate well. Among other things, we got data aborts in several places, most annoyingly sometime after boot_relocate_fdt. This was using a 64-bit Ubuntu Precise Pangolin (12.04) installation, the standard "arm-linux-gnueabi-gcc-4.6" (4.6.3-1ubuntu5) compiler and other toolchain components (no modifications made).
Using USE_PRIVATE_LIBGCC=yes solved the issues, as did changing to the gcc 4.4.7 (4.4.7-1ubuntu2) and using either private libgcc or the one provided by the toolchain. This is not the first problem we've ever had with the Linaro gcc toolchain, especially not with 4.6. So far, reverting to building using gcc 4.4.7 has solved all the problems, and we're using USE_PRIVATE_LIBGCC by default now anyway because I don't see the point in using the one provided with the toolchain if it is such a huge unknown and U-Boot provides a compatible feature anyway. I'm not sure what anyone on the list is going to make of this or if it influences some design decisions anywhere else in U-Boot, just that I was nagged incessantly to "report my findings" - we all knew the Linaro compiler generally sucks already, though, right? -- Matt Sealey <m...@genesi-usa.com> Product Development Analyst, Genesi USA, Inc. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
