problem with the drivers for the altera pcie core

1,003 Views

Hi,everyone!

I have built a project to use the pcie core and dma controller in SOPC method,and i have to write a WDM driver for the system. Now,i have came across a problem with the driver.

That is, i want the DMA controller to read data that i have assigned in the WDM dirver via the PCIE Tx slave(i have connect the DMA read master with PCIE Tx slave), and i think i have to config the DMA readadress registers via the DMA controller's control slave port and the A2P translation table via the PCIE Rx master port.But, i don't know which address i can use to config these two registers, the physical address of the memery i have allocated? the logical address? or other else?
