Need Help in Testing FTL code using NAND simulator

[Brajesh Sharma <s.brajesh@mobiveil.com>]

Hi All,

I’ve started recently working on FTL thing and now I need some kind of 
help from all of you as I’ve seen similar kind of thread just now.
I'm having a Huge FTL code (block + character) driver which is a linux 
kernel module and is having a specific PCIe based hardware. But i don 
have that H/W so I'll be porting this code for generic Flash device but 
i'm not sure how to test the code in absence pf H/W. I'm removing the 
character driver complications and wanna use just block driver which 
offers management module implementations (bad block , GC, Address 
mapping etc).
I've come across NANDsim which i find can be really useful in my case to 
emulate the virtual flash device in host memory (RAM) . But NANDsim is a 
part of MTD subsystem and My code doesn't have anything to do with MTD. 
SO i'm not sure can i use it with my code. I've seen usage of NANDsim on 
web with mtdblock device & on top of it an NFTL or something else though 
i'm having my own block device driver with FTL implementation in it.

e.g. NFTL/UBIFS --> mtdblock/mtdchar --> Virtual Flash (RAM) using 
NANDsim ....

But for me it'll be like (FTL+block driver) --> Character driver --> 
Virtual Flash (NANDsim)... or do i have any other alternative ????

Any help would be appreciated.
