If you are using the AT91RM9200 and dataflash, the proper procedure is to:
1) Boot the CPU using Bootrom
2) Download dataflashboot.bin, The bootROM will store this in internal SRAM
CPU will automatically jump and execute dataflashboot.bin from SRAM
3) Download dataflashboot.bin again. dataflashboot.bin will store this in dataflash
4) Download u-boot, dataflashboot.bin will store this in dataflash.
5) Reset the system
6) The BootROM will find dataflashboot.bin and will load that into SRAM.
dataflashboot.bin will load the u-boot into SDRAM and jump and execute U-Boot.
Best Regards
Ulf Samuelsson
