How can i Initialize ddr data through EMIF ip

Hi,

 

Please take a look at this:

https://www.intel.com/content/www/us/en/docs/programmable/683216/23-1-2-7-0/about-the-external-memory-interfaces.html  

 

After I reset ddr through the emif ip, the data I read was random.

 

I know I can write 0 through the Avalon Memory-Mapped Interface to Initialize ddr, but it's too slow.

 

How can I initialize ddr data to 0 quickly.

 

Thanks,

 

kokodo

Hi Kokodo,


Every time the reset is triggered, the EMIF IP will perform the calibration process.

After the calibration process has finished, the user can access the controller.


So far the user can only interact with DDR by performing write and read transaction through EMIF IP.

I don't think we can initialize the data through EMIF IP. It's need to write through Avalon Memory Mapped Interface.


Regards,

Adzim
