Good day !
I have create a project for Quartus II 7.2 following the PCI Express Compiler user guide, Chapter8 (SOPC Builder Design Example). I use Application notes AN532, and test solution pcie.exe and simple_dma.exe from AN532 arhive. This examples also can work best. This test solution use Jungo Windriver wdapi811.dll functions.
I have create oun driver and test application.
This is test application use# include <condefs.h>
USEUNIT("../../pci_diag.c");
USEUNIT("../../pci_lib.c");
USEUNIT("../../../shared/diag_lib.c");
USEUNIT("../../../shared/wdc_diag_lib.c");
in Jungo windriver directory.
In system resouses i see two areas of memory BAR0 and BAR2.
I can read and write data to BAR0, but this operation is slow.
I want use the DMA controller, but do not now how config DMA controler and read \ write data with help Jungo Win driver function.
Config DMA controler from BAR2 ? Is it true ?
How I can read and write data - from BAR0 ?
