Placing the final boot image is left to user who flashes/burns it board. But it should be same as _TEXT_BASE (this is being removed now. Orion5x is arm based). Also look at <u-boot-src>\arch\arm\cpu\arm926ejs\start.S & <u-boot-src>\arch\arm\cpu\arm926ejs\u-boot.lds for more info on how linker is instructed to place the starting code at predefined address. > I'm basically trying to make sure that my CONFIG_SYS_TEXT_BASE is correct > (the address in the flash to which I write the whole u-boot.bin file, right?. > This is passed to linker as the entry point. > Thanks > > Rogan Regards, Gururaja _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
