Default Problems with PCI-CardbusCard (interface is an FPGA) on Windows - 10-10-2003 , 02:20 AM






Dear all,
I have one big problem with my cardbus PC-card.
I developed this card on my own and a collegue developed the driver. The
CardBus-interface is included in an FPGA APEX20K100E.
Since there were some statements in the Specifications about burst read, I
adapted
everything on this card for this burst read. But when I insert the card in a
Notebook and read my memory space, no burst happens. All what is done are
normal single accesses. What do I have to do to perform a burst read? Are
there any settings which have to be made to enable such a burst?
My PC-Card is burst-read capable and on the PCI-to-CARDBUS-Bridge I also set
the MBURSTUP and MBURSTDN-Bit to enable such burst. The sys-driver itself
should also be burst-capable I think.

I would be very pleased if anyone could help me solving this problem.
Thanks in advance

Joachim
