Cannot install PCIe driver (altera_dma.ko) on Ununtu Linux 18

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-chi...), 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 :

Hie, Unfortunately we don't have a different pcie driver version for the design in the design store. Please check if you are able to build a new Kernel linux as shown below: https://rocketboards.org/foswiki/Documentation/AlteraArria10SoCVirtualPlatformBuildLinux Regards, Nathan
