Using two different SDcard with SDMMC

Question asked by JC Lebreton on Mar 13, 2018



I was wondering if SDMMC can drive more than 1 SD card at a time. 



I understand that the cube or the SDMMC functions are not involved here.


I also noticed that FATFS_LinkDriver() use a variable called VOLUMES which is the number of logical drives that can be used. 


So my questions are : 
Do i have to simply change the variable VOLUMES from 1 to 2 ?

Can i do such a thing? using two sd card on the same SDMMC wires ?


and before you ask, i have a working project using SDMMC 1 bit wide bus !

Thanks in advance for all your answers!
