Jungo Windriver and PCI bursts

[zape]

jungo burst transfer

I am starting a PCI application based on a self developed hardware. It is a board designed to be plugged on an standard PC.
I need to write in pci burst transfers, about 1K byte per transfer, and I have tried several ways of making the writes (following winDriver doc, but I can not get so fast transfers (3 or 4 dwords) is maximum.

Anyone suffered from the same trouble? Is the driver the problem or it is in the PC PCI arbitrer?... or perhaps on my hardware?

Any advise should de helpful.

I too am interested in this.

1. Is there any limitation on the PCI burst size on the mother board?
2. Is the PCI arbitration priority configurable. ie, can I program higher priority for any particular PCI add-in card?

I'm very interested, but just for the future.
I always wanted to do some PCI hardware, but I never had the chance.

What type of PCI bridge are you using. To support PCI burst transfers your device has to support MASTER mode. If your device supports only target mode then You'll be able to transfer only one DWORD per burst.
