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

Thank you, Dave,

We actually got rid of the DDR2 once and has on-chip memory and SGDMA at Qsys. But it didn't seem to help and Bar0 sill didn't appear at the WinDriver memory tab. There was nothing under WinDriver memory tab.

Could you diagnose this problem?

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
