Cyclone 10 GX FPGA Development Kit PCIe master images

Hello. We've bought Cyclone 10 GX FPGA Development Kit to test PCIe connection. I use two reference designs: Cyclone10GX_PCIeGen2x4_AVST_18_0_project - AN855 Cyclone10GX_PCIeGen2x4_DMA_18_0_p...

    So, I've changed design to reduce BAR2 size down to 1G.

    Now the PC boots normally, driver in Win and in Ubuntu loads successfully.

I've made a little trick. I've programmed the board with jic file with Avalon-ST image (AN855), started PC and paused booting, when BIOS screen appeared. Then I've donloaded sof file with Avalon-MM-DMA(AN829) and let the PC boot OS.

1. Ubuntu.

lspci-v gave the result:

But after /sbin/insmod altera_dma.ko, the file /proc/devices does NOT contain altera_dma. This is not good.

Earlier, I've compiled Avalon-ST project with PID\VID of MM-DMA. In that situation the file /proc/devices contained "altera_dma".

So, something failed, while inserting module while MM-DMA was programmed to board.

2. Win10.

I've repeated boot steps, then boot the Windows10. In Device Manager the board was found with correct PID\VID of MM-DMA project, but the driver was not istalled. Error message stated:

May be this firmware is too resource consuming?

Please suggest, what should I try to change in example project to make it possile to install the device at least in Ubuntu.

Thank you.
