Cyclone V SoC Dev Kit PCIe End Port Example

Hi Angad,

I am testing the following design: http://rocketboards.org/foswiki/view/projects/pcierootportwithmsi

If you Look into "Open Issue" - FB 165881 – Kernel can’t boot up if don’t have end point

I have applied the patch that they are giving. It works fine on the Dev kit, But I tried the same patch for Other Cyclone V Device(5CSXFC6C6U23I7ES) The patch seems to fail.

Basically from the patch I understood that the RootPort is being forced to complete the Enumeration But I dont understand why it wont work for other device other than Dev kit.

That is a terrible issue - its like saying "Sorry, your PC cannot boot if you do not have a card in the PCIe slot"!!!

Sorry, I've steered clear of the SoC devices for exactly this type of reason. I expected "teething" problems and didn't want to be the one to find them (been there, done that with earlier new generation devices).

I didn't read any of the code. Perhaps there is just a "bad decision" in the RTL or in the bootloader code that is the cause of this issue.

Cheers,

Dave
