to write the driver for my own ip core

have to write the driver for my IP core which mainly transfers the data between the ip core and the plb bus.

related materials.

some documents about it?

Well, since you are going to write drivers for cores connected to the PLB I suspect that you do have the EDK. There is a 'Device Driver Programming Guide' in the Processor IP Reference Guide which gives you the basic knowledge. You also have quite a few drivers in the ./EDK/sw/XilinxProcessorIPLib/drivers catalog of your EDK installation. I've used them as examples when I have learned to write device drivers for EDK. The included drivers in the EDK also gives you an idea on how to write the .mdd and .tcl files.

Good luck.

cheers!

Hmm.....

Is you question that you don't how how to format your c functions so they conform to the Xilinx Driver 'standard'

or....

Is your problem that you don't know how to access your hardware at a low-level?

Hi all,

Thank you for all your suggestions.

I have both ISE and EDK7.0.1. At first, I don't have any conception about how to connect my IP CPRE with the plb or opb bus. I just know one side is the ip core written in VHDL, and the other side should be some driver written in C.

I have read the drivers of Uartlite and spi, but I still couldn't be clear about how to connet the two sides. How to get the .tcl files?

The articles suggested by Kunal are very good. I am reading them at present. I will discuss my thinking with you later.

Thanks to all of you! Athena

The "Create and Import Peripheral Wizard" (chapter 4:

is a good starting point. Use the skeleton files created as a starting point for your own custom core. An example device driver to access the custom core from the procossor is generated as well.
