Why am I not able to load files from a partition with U-Boot?

For some reason, my U-Boot does not seem to be able to load files from my FAT32 partition: => mmc part Partition Map for MMC device 1 -- Partition Type: DOS Part Start Sector Num Sectors UUID Type 1 2048 62519296 a1d1165e-01 0b => fatls mmc 1:1 52560 file1.bin 1984 file2.bin 456 file3.bin 64 file4.bin => fatload mmc 1:1 0x0001FF80 file1.bin ** Reading file would overwrite reserved memory ** Failed to load 'file1.bin' Why do I get Failed to load and how can I get around it?
