Hello All,
I am working with an Arria 10 GX platform. I want to leverage a design example for PCIe (https://fpgacloud.intel.com/devstore/platform/16.0.2/Standard/an690-pcie-gen3x8-avmm-dma-with-on-chip-memory/), however, when I try to install the linux driver (altera_dma.ko) i get an error:
user@user:~/Documents/AN829_driver$ sudo insmod altera_dma.ko
insmod: ERROR: could not insert module altera_dma.ko: Invalid module format
Apparently this is caused becaused the version of the kernel used to compile the module and the kernel version on my workstation are different:
user@user:~/Documents/AN829_driver$ dmesg | grep altera

Is there a different version of the pcie driver or is there a way to get the source code to obtain the source code and compile my own driver? Is there any other workaround that you can recommend?
I have followed the recommendations found below without positive results :
