11 years ago --- Quote Start --- I run the "PCI_Express_in_Qsys_Example_Designs" sample on "Cyclone IV GX starter kit" board. Running SGDMA successed. I want to know wheather DMA is ended by using interrupt. But i can't get the interrupt notification all the times. Environment is: WindowsXP SP3 Jungo WinDriver PCIE send "legacy level-sensitive interrupt" Steps: 1. enable interrupt at 0x0050 register 2. clear interrupt state 0x0040 3. useing WDC_IntEnable register IntHandler function 4. listen in IntHandler function 5. clear 0x0040 interrupt state in intHandler function 6. printf("Got a interrupt\n") in IntHandler function I can't get the interrupt all the times. I also got the same result by using "MAILBOX" testing. --- Quote End --- I want to know wheather DMA is ended by using interrupt. But i can't get the interrupt notification all the times. Hi yanshine, I'm wondering if you got through your problems. I am seeing the same issue on my board using a stratixV device. Its 3 years ago, but I'm hoping you have some knowledge to share. -V
