Mount FATFS on STM32H735G-DK's external HyperRam chip

[SScot.4]

Hi,

​

I'm interested in mounting a dual drive fatfs on the ​STM32H735G-DK's external memory chips connected to the octospi interface (512M NOR flash MX25LM51245GXDI00, 128M HyperRam S70KL1281DABHI023) I'm not familiar with HyperRam and I'm wondering is it suitable to mount a volatile file system using fatfs to this chip while in memory mapped mode? My plan is to run my application code from the HyperRam chip, and I'd like to have access to a volatile file system mounted on the HyperRam, and a nonvolatile file system mounted to the NOR flash. Are there any limitations I may face with this architecture?

​

Thanks

Sounds like it should be workable.
