This trick can not work with the ELDK toolchain, which also I don't want to think about and be involved in discussion any more. See: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/81572/focus=81735 Users who need to dig into this area should install the ELDK first, build little-endian targets with it by yourself, then find a way to handle endianness appropriately which works for both the ELDK and non-ELDK toolchains. Or I may miss something. If it's already verified with the ELDK, please let me know, thanks. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
