altera_dma driver PCIe under linux

Honored Contributor II



I am testing the PCIe dma with the Arria V starter kit using the reference design from Altera. The design works with the GUI under Windows. But I need to modifiy the program so i need it to work under Linux which it doesn't. The PC is the same, the FPGA keeps programmed during reboot (so after restarting the PCIe-program still works under Windows) and is detected under Linux too. 


I have found an error which I don't understand: 

sudo lspci -vv | grep Altera 02:00.0 Non-VGA unclassified device: Altera Corporation Device e003 (rev 01) Kernel driver in use: Altera DMA pcilib: sysfs_read_vpd: read failed: Input/output error 


Has someone an idea or encountered the same problem?
