How to modify the mfs block size when using mfsgen

[ceejliu]

1. I modified the MFS_BLOCK_DATA_SIZE (default is 512bytes) in file xilmfs.h.

2. When using the mfsgen to generate mfs file, the default block size is 532(512 + 20). Thus the format can not match, the file saved in mfs can not be detected.

The question is the if the block size can be modified when using mfsgen command?

Hey @ceejliu

It looks to me, that the Xilinx mfsgen only supports the default 532 (512+20) byte block size and you need to write your own mfsgen to work with different sizes.

Dear @hpoetzl,

Thanks for your reply

The mfsgen is just a batch file, it actual called the loader.bat and rdi_xilmfs(an application in the path C:\Xilinx\SDK\2015.1\bin\unwrapped\win64.o\rdi_xilmfs.exe).

I want to modify the block size, if the only way is to reprogramed the rdi_xilmfs.exe?

I have no idea about the rd_xilmfs.exe.

Thanks a lot.

Best regards.

Yes, that's how most of the Xilinx tools work ...

At least the help doesn't show an option to change the block size.

I have no idea about the rd_xilmfs.exe.

Me neither, that's the problem with closed source, you never know what hidden features there are ...

Best,
