Help: Windows didn't assign Bar0 to PCie (address mapping is not correct)

Thanks, Dave.

Then how to use Qsys to connect to large memory chip (DDR II)?

If I assign large Bar size covering the whole address of DDR II, computer will not boot.

What to do to make large memory chip to work with PCIe?

Thank you very much!

The PCIe spec will not stop you, but your particular hardware might. My EliteBook will not boot with a BAR of 256MB.

Because you did not change the BAR size by doing this. Look at the report on the Qsys GUI. Look at the synthesis report.

Look at this document here:

It has some comments.

To try and isolate this problem, start with just the on-chip RAM in the BAR at a base address of zero. You can use the "Address Map" tab to re-assign the addresses.

Once you can confirm that you can boot windows, you can increase the size of the BAR (the offset of the on-chip RAM) until it breaks. Then you will know the limits for your particular hardware setup.

Cheers,

Dave
