Hello all,

Well, I just spent a couple of fun days trying to track down an issue I 
was having with my implementation of the YAFFS direct interface. I had 
thought everything was fine, but I noticed that when I started to copy 
larger files to my YAFFS partition, the files were being corrupted.

Eventually, I determined that this was happening when the garbage 
collector ran. To verify, I modified the yaffs_CheckGarbageCollection() 
function to just return YAFFS_OK without doing any garbage collection of 
any kind. As soon as I did this, all of my problems went away.

I do not believe that this is a bug in the YAFFS code. Rather, I think 
the problem has to do with my definition of a block size and what is 
physically hooked up on my board.

I have two NOR (StrataFlash) devices hooked up together to look like one 
device. Is there anything special that I need to do with this situation?

Currently, each individual chip has a block size of 0x20000 bytes. So, I 
have been reporting to YAFFS that the block size of the device is 
0x40000 bytes. That way, when YAFFS wants to erase a block, I should be 
erasing one block from each chip and there won't be any overlap.

However, something about this is most definitely *not* working.

Any ideas would be great.

Thanks,
	--mike
