fatfs with ramdisk and dataflash

Hi everyone,

I'm developing an application using a custom board based on MK66, MCUXpresso 10.1.1 and SDK 2.3.

On the board there is external battery backed up RAM, used for a ramdisk, and a 8 MB dataflash device (AT45DB321E), where I need to implement 2 different disk.

I've read the FatFs docs and it seems that I can handle only 1 disk of the same type (ramdisk, SD disk, MMC disk).

Did I misunderstand something?

How can I handle my devices?

Many thanks

Biafra

Hi Biafra:

In theory it is possible to write into several different physical discs, but I have never tried it in practice.

Regards
