The problem is that the first patch posted here places .rel.dyn after .bss, so when dumping u-boot.img, all of .bss is included in the file. Keeping it before .bss allows the flat binary to omit .bss as usual. Using the patch quoted above, I get a working u-boot from all combinations of gcc and binutils I cared to try, including gcc 4.5-linaro with binutils 2.20.1. -- Måns Rullgård m...@mansr.com _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
