Hello Wolfgang, AFAIK the AT91RM9200 Boot Sequence only allows 16k-4k size for the first Programm, E.g. the loader.bin. The u-boot.bin ist about 92k, so it cant't be loaded directly. First the loader.bin ist executed which initializes the external SDRAM an it then loads u-boot.bin to external SDRAM. How can the u-boot be configured to be used so, i didn't find any hints.

make at91rm9200dk_config make all
What makes you think the default configuration of U-Boot would need any loader.bin stuff? Instead, it will boot directly.
Best regards,
