Flash FS Support Question

All,

According to the Keil website the FlashFS library supports the following SD memory cards:

"....and SD/MMC/SDHC Memory Cards."

I have a requirement for SDXC card support (>32GB). Does anybody know if this LIB is capable of supporting up to 2TB memory?

It seems to me that it would (except for maybe some 32 bit variable problems), because the addressing of SDHC is done by 512 byte 'units' to circumvent the addressing issues with earlier SDSC cards. This method suggets that for up to 2TB (current SDXC spec requirements) a 32 bit variable will suffice (ie: So 2TB : (2,199,023,255,552 / 512) = 4294967296 (-1) (0xFFFFFFFF) which fits in a UINT32).

Many thanks.
