Correct, since we're trying to find the post-relocation address of board_init_r, we should add the relocation offet to its link-time address, not run-time address -- the fact that both are the same right now is only incidental. Thus: Applied to u-boot-arm, thanks. Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
