PicoZed 7015 PCIe PIO Demo

I wanted to let everyone know that a PCIe PIO design has been posted for the PicoZed 7015.

It can be found here:

http://picozed.org/support/design/4701/76

Search "PCIe PIO Demo"

It is called a Demo, however does include the Zynq source files and instructions on how to generate this. The reason it is a demo, there is a software driver / Windows application. The source for this has to be requested from your local Avnet / Silica FAE and it is NOT included.

Thanks Dan - this looks like just what we need. Is there a Linux driver for this?
cheers

Hi there Graham,

Sorry, at this time there is only a Windows Driver.

A quick Google Search seems to only offer Windows based drivers.
I would contact your local Silica / Avnet FAE and request a Linux driver. We can at least provide you with the Windows driver, which might be able to be used as a guide to help you make a Linux driver.

I have tried to contact our FAE, but he is not replying. I have tried loading the boot.bin file on to an SD card and setting the SW1 dip switches on the 7015 to boot off the SD (a trick that required a fair bit of detective work). I tried sticking it in a windows PC and disabling the signature enforcement!! so that the driver would load, but the card is not recognized. I also tried generating an mcs file and loading on to the qspi flash and resetting the dip switches, but still did not work. Any ideas what I should check?
thanks
Graham

Graham,
Have you performed the rework noted in the Errata?

Hi, I want to know that if I can use the source file with PicoZed 7030 to test the PCIe working.
Can I use same source code with 7030?
If yes then what changes I need to do in the source code.

Hi there,

I have not tried this, but I would start with downloading the demo zip file. In there you will find the drivers that need to be installed. Install them.

The drivers are looking for a specific address space (noted in the instructions). If you were to open the 7015 project (included in the zip), change the chip selection to a 7030, that should work. Again, you need to ensure the SAME address space is being used!

I would also double check that the changes made to the Verlog files were not overwritten when you change the chip type to the 7030. You can see the modified files for the 7015 in the patch folder.

Thank you for your interest!

Hi,
I tested the firmware on PicoZed 7030, and I can confirm its working on 7030.
Now I need to access registers in the code. Please refer me to the PCIe driver tutorial if you know any, that how can I access to the read and write register in the code (like LEDs register in the code) from PC.
Also I emaild to the relative AVNET department for software source code but there is no response (two weeks past).
Thank you

Ok. I finally found a way to access the registers without GUI by using Jungo Windriver software.
Thank you...
