How come you want to execute it from RAM? Is the board without flash? Could you instead replace the "bootstrap" loader with U-Boot? It the SDRAM controller is already setup, I guess you must recode U-Boot and tell it not to touch/re-initialize the memory controller... Btw, look at http://www.denx.de/wiki/view/DULG/CanUBootBeConfiguredSuchThatItCanBeStartedInRAM - Frank _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
