Do you need a file system whilst doing FPGA accesses? If you put the
sd card in the pc, delete every file, then create a single file which
is the size of the available space you will find that all the fat
blocks are sequential. The fpga can use the memory as a single block
which then needs simple sorting out back in the PC. I've done this
with no problem.

Thanks everybody for really useful ideas.
I think the best solution for me would be DOSFS with SPI core because
I need to write multiple image files to micro-SD card and later make
them available to PC users.
