FAT support in prelaoder: compilation issues

Hi, 

I'm trying to build preloader with FAT support and compilation process fails. I've checked SD/MMC boot and FAT support. In files lowlevel_init.S and spl.c there are some undifined references: __sdram_stack_start, __sdram_stack_end, __bss_fat_start, __bss_fat_end, __malloc_fat_start, __malloc_fat_end. So make process exit with failure. How can I solve this problem? 

 

Thanks.

Thank you for the link. Matter of fact the compilation fails when FAT SUPPORT and EXE ON FPGA are checked together. It is strange because what if I wanna boot preloader from FPGA OCRAM and then load my app from SD/MMC FAT partition. It is not forbidden directly somewhere in documentation as I know.
