i came to that conclusion ... i looked at the u-boot.srec file that was generated and, sure enough: S00E0000752D626F6F742E73726563C0 S315FE00000042424242424242420606060606060606AC S315FE00001000000000000000000000000000000000DC S315FE000020A0A0A0A0A0A0A0A06060606060606060CC ... snip ... so definitely linked for flashing to beginning of NOR flash at 0xFE000000. so i suspect i could just flash it and reset and it would work just fine. and never mind, i found the answer i was after: http://www.denx.de/wiki/view/DULG/CanUBootBeConfiguredSuchThatItCanBeStartedInRAM i was hoodwinked into thinking it would be easy because i found this page: https://blackfin.uclinux.org/doku.php?id=bootloaders:u-boot:tftp_loading_files of course, that page is for the blackfin, precisely one of the platforms the denx page says it *can* work for. grrrrrrrrr. so, before i commit myself to this, who's the PPC/MPC8315E-RDB expert on this list who can confirm a stock u-boot should flash to NOR and just plain run? rday -- ======================================================================== Robert P.
