When the map_sysmem, then the fatwrite command can support sandbox. Following command will show how to use it: => sb bind 0 sd.img => fatls host 0 => fatwrite host 0 $memaddr filename $filesize

Thanks for the patch.
You should remove the cast here - map_sysmem()'s first parameter is a U-Boot address as a ulong.
size = file_fat_write(argv[4], buf, count);unmap_sysmem(buf); if (size == -1) { printf("\n** Unable to write \"%s\" from %s %d:%d **\n", argv[4], argv[1], dev, part);-- 1.7.9.5
