Getting started using the EIM in the iMX50

[jedrumh]

Hello,

I just need some help getting started. I have to use the EIM, in an iMX50, to talk to an FPGA (Stratix IV). Can someone please give me a place to get started? The EIM needs to be in asynchronous mode and the FPGA will be on CS1. I'm running Linux. I'm assuming I have to setup the EIM pins in mx50_rdp.c (I did this for GPIO) but how do I know what the base address is? How do I configure the bus? I can't seem to find a straight answer in any of the documentation. Any help would be greatly appreciated.

Thanks!

You can find the EIM base address in i.MX50 Reference manual chapter 2 "Memory Map".

For the EIM details, please read the Chapter 23.

Is there any EIM driver support available in Linux?
