Hi all,
I'm up to replacing our own flash file system with one that has more features.
I came across the Spansion FFS and would like to compare it to littleFs and SPIFFs.
I searched through a lot of the documents that I received about the Spansion FFS but could not find anything on the resources (program / data memory / RAM) that is being used.
I am using a TIVA Cortex-M4F processor and would like to access a S25FL127S by SPI (1 data wire, only).
Could someone give me a direction, please?
Best regards,
Rainer

Hi Rainer,
Thank you for your response.
As per our measurement before, if you use whole 128Mb for FFS, the minimum RAM consumption is:
7KB (BD) + 7KB (FS) + 5KB (stack) = 19KB

Hi Rainer,
Thank you for contacting Cypress Semiconductor.
I am not clear about your query. Are you requesting for the Cypress FFS package or are you requesting for a code example that demonstrates the FFS package usage?

Dear Apurva,
I have the code but like to know which amount of RAM and program memory is being used in the processor.
Some call it a footprint. Just like this, e.g.
http://elm-chan.org/fsw/ff/doc/appnote.html#memory
Just to check if it's feasible for my project before I integrate and compile it.
Best regards,
Rainer

Thanks Apurva,
do you also have a rough idea on the program memory footprint?

Hi Rainer,
The program memory will consume roughly 108KB (based on rough calculation).
