Hi Everyone,
I'm following this link http://www.alterawiki.com/wiki/reference_design_-_gen3_x8_avmm_256-bit_dma_-_stratix_v to setup DMA communication for Stratix V device. I have successfully program the FPGA and the hardware side seems to be Okay. However, I have difficulty running the Linux Driver provided in the above link for Linux. Before telling what exactly the problem is it might be good to know that I have ubuntu and the kernel version is 3.19. So, trying to install the driver I got this message running dmesg. altera dma 0000:01:00.0: can't enable device: bar 0 [mem 0x00000000-0x000001ff 64bit pref] not claimed
Worth to mention, when I run lspci command here is what I get: 01:00.0 non-vga unclassified device: altera corporation device e003 (rev 01) So I assume there should be any problem with the hardware side because the linux can detect the pcie connected device. Is anyone have any thoughts what might be the problem ? Thank you in advance for any help.

hi
can you check with lspci --xvv?
if you got the address for your bar then you might need to look into your driver.
