PCI Burst Transfer in SOPC Builder

hi, girls and guys, i want to design a PCI Master device with the Altera PCI IP inside the SOPC Builder. But i met some problems, need ur help!

my hardware inside sopc builder:

1 hardware components:

a) PCI IP: Master mode, 32bits/33Mhz, danymic translation table, 2 pages, page size:4kB; 3 bars( choose auto size)

http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif DMA IP: 13bits, burst transfer enabled, and specify burst length 16Word

c) on chip ram: 4k,32 bit

2 connection:

a) bar0--->PCI Control Port, bar1--->Dma Control Port, bar2 -->on chip ram;

http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif dma read master---> on chip ram,

dma wirte master---> pci bus access port;

I wrote a driver to control the dma, and the sequence for the register setup follows:

1 Clear DMA Status Register;

2 Avalon to PCI Translation table entry 0: address of the allocated physical page( page size :4k), and also clear the lower 2 bits to 0( indicating memory space)

3 Set up DMA Read address register: address of the on chip ram(0x00000000)

4 Set up DMA Write address register: address of the pci bus access port( 0x00000000)

5 Set up DMA Length register: 10

6 Set up DMA Control regiter: 0x0000008c,

But, i can not see the data coming into the allocated physical page,

any idea and suggestions are welcome.

thanks!
