Dear All,

Is it Possible to Connect another FMC device along side of IS42S16400J in STM32F429I-DISCO

board, does the Address line and Data line causes any problem to the other FMC device from the onboard SD RAM(IS42S16400J )

Note: External device Voltage is same as the SDRAM Voltage level, Control lines are different for the External interfacing device,Except Data and the Address bus are shared Between SDRAM and the External FMC device.

Thanks for your valuable response, in advance.

This is my question too. It seems that the answer is yes, as I took a look at the schematic of evaluation board.

But my question is, when we want to read data from nand flash should we disable sdram?

Is there any example of doing this?
