using EBI and DRAM in MPC5675K

I have a project using DRAMC in MPC5675K(BGA473), however, there are new requirements to communicating with a new device with eight databus and four address bus.

I wonder whether the EBI can be used for this new purpose when the DRAM functionality was already used in former project.

And if not,  how can the EBI and DRAMC be used at the same project with paralell communication method?

Thank you.

Hi, I am afraid it is not possible to use both EBI and DRAM together. You may choose either EBI or or DRAM as their pads are shared, but the functionality must be explicitly chosen by SIU. It is not supposed to work simultaneously.

Hi, David,

Thank you for your reply.

My problem has been solved by turning to a SPI interface device.
