Hi,
I am using S29GL01GS parallel NOR on STM32F4 microcontroller.
I am looking for FFS and BD support for this part.
The spansion FFS brochure directed me to a link which appears outdated.
Please assist.
Thanks all.
Solved! Go to Solution.

Hi Krishna,
We are also using S25FL512S Flash chip in our design for storing data.
I am currently looking for Spansion Flash File system code for evaluation.
Also interested to know the minimum system requirements like RAM usage and code foot print as we are using FreeRTOS and MCU configuration of 32 KB RAM and 256 KB Flash
Please guide how to get that

Hi,
we are using the same 64mb nor flash with a pic32mz2048 which has 2MB Flash and 512kB RAM. Our source code is huge so we need that kind of a big chip. but after getting the spansion ffs to work a few years ago, i remember that 32kb ram is about the mem that you need for the spansion ffs alone if i remember correct.
there are a few options to tweak to get a lower ram footprint (cache option etc.) but then your program also has to be extremely small.
(in our application we also have a tcpip-stack with http-server with a lot of functionality and heavy udp-communication running so that explains why we need such a big mcu)
i would consider a chip with more ram to be on the safe side and still having the option to by a much bigger one that is compatible if things are going too tight.
i hope i could help you with that information,
stefan.

Hello Raj,
We will register and give access to FLASH File System (FFS) . One of our engineers will send you the Login ID and one time password to you.
He will sent you the URL as to where to access the Cypress (Spansion) FLASH File System (FFS) link also.
Best Regards,
Krishna.

Hi,
I also need the source code of FFS and associated drivers. Can you please share?
BTW: is there a way to request in automated way? I can not believe that such a big company such as Cypress needs to process requests from the forum one by one.
Thanks.

Hello Krishna and Albert
I am trying to interface External NOR FLASH (S25FL512S) to the Microcontroller STM32F091RC via SPI .
[1]Could you please send me the LLD (Low Level Driver), BD(Bloack Driver) and FFS(Spansion Flash File system code) for the S25FL512S
[2]Could you please provide sample code NOR flash interfacing via SPI (with structured layer architecture -->ie Hardware Layer Abstraction Layer Driver, Low Level Layer Driver , RTOS AND APPLICATION ) for any Microcontroller ?
[3] By means of some tool, can we generate Low Layer driver(LLD) for SPI NOR FLASH(S25FL512S) and this LLD can it be used in STM32F091RC (ARM CORTEX M0)MCU?
I would be glad , if you could reply at the earliest .

Hello Krishna and Albert,
I am an embedded systems software developer from Austria and I am working now for about three years with the Spansion FFS in combination with a S25FL512S NOR Flash (64MB) and a PIC32MZ microcontroller.
It works good but sometimes the garbadge collector takes too much time and our cooperative multitasting system is then blocked.
I optimized the system by manually calling the garbage collector in advance ("FTL_ForcedGC" in ftl_gc.c) so when larger writes on the file system are coming the garbage collector does not need to be called.
But this is still not a perfect solution, cause calling the garbage collector - even when the system has low load - can take up to a maximum of nearly 1000ms which means that the system is blocked for that time.
Now i have the task to enhance the Flash Translation Layer with some kind of background garbage collector that splits up the work into smaller junks and does this when the system does not have too do much. The benefit of this is a better reactive system with no long blockages - especially when writing files.
I am now at the code analysis which is a little bit of a pain (in the as) cause there is almost no documentation in the source code. But I think i have to go through with it.
What I wanted to ask you guys is the last version of the Spansion FFS, so that I do the work with the actual version and not on some outdated old version.
Would be great if you could support me with the actual code.
Thanks,
Stefan.

The documentation says that Spansion FFS is available at no cost for Spansion customers. Does this mean there is a license fee if you are using non Spansion flash devices? Are flash devices from other manufacturers supported? And if so could you give me some information on the licensing costs and supported devices.

Hi Xander,
Basically, the Spansion FFS can only be used with Spansion (Cypress) flash memory parts. We don't have any license programs for the Spansion FFS to be used with other vendors' flash memory parts.

Takahiro

Hi
We used s25fl128s in our xilinxz7020 board,we are trying to find a filesystem suitable for it.
we have tried jffs2 and spi ffs,they did not satisfy me.
Jffs2 cost a long time at mounting and spi ffs do dot support dictory.
So I am currently looking for Spansion Flash File system code for evaluation.
And Dose Spansion Flash File system has the limition?
