Ok,this is wrong, But it is code from version 1. The V2 use the correct sub instruction. > > Then we subtract TEXT_BASE from absolute address of SMRDATA.

So the address 0x500 and 0x10000500 points the same location in flash. > regards Jens Scharsig _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
