hmm, the other reloc syms are named _GOT2_TABLE_ and _FIXUP_TABLE_ so I think I should follow that. > > -Scott > > [1] Global offset table table? :-) :) Figured I should mention that I have added -msingle-pic-base(from ARM) which works nicely with -fpic(not sure if -fPIC is possible) and reduces size even more: size u-boot-before text data bss dec hex filename 230595 6580 24228 261403 3fd1b u-boot size u-boot-after text data bss dec hex filename 222779 6580 24228 253587 3de93 u-boot If you have 8 KB free DPRAM/cache one can move the GOT tables there while in flash and create true PIC Jocke _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
