DDR4 I2C port

Dear Sir,

 

I am using DDR4 in DE5a-NET DDR4 board. I don't know why the controller IP has no SDA and SCL for the I2C. Should I write it by myself? If I want to use the port. Thanks.

Dear Peter, Yes the DDR4 IP only have the avalon mm (AMM) port for user access. If you want to use it for SDA and SCL, you have to write an custom logic that translate AMM to SDA and SCL.

I'm sorry for inconvenience caused.
