You won't ever need or want it again. > It is possible, This is how you boot the AT91RM9200 from dataflash. First the bootROM is executed and this loads "Dataflashboot.bin" into internal SRAM and jumps to the beginning. Dataflashboot.bin loads U-Boot into SDRAM and jumps into U-boot. And no, you cannot replace Dataflashboot.bin with U-boot (unless you manage to shrink it to 12 kByte) The at91rm9200dk needs a little tweaking for this to work. Cannot link it to 0x00000000. /Ulf > Best regards, > > Wolfgang Denk > -------------- next part -------------- A non-text attachment was scrubbed...
