DMA example Arria 10 PAC

[AIvan11]

Hi,

I am trying to run DMA example from the OPAE samples on Arria 10. I managed to run other examples such as nlb and hello_afu, but dma_afu example gives me following error:

Running test in HW mode Error fpgaDmaOpen: no memory Error fpgaDmaClose: invalid parameter  

Can you help me resolve it. Thank you.

Which version of OPAE are you running? Which OS?

[AIvan11]

I use OPAE 1.1 on Ubuntu 18.04 server.

Hello,

Can you confirm if you have sufficient memory allocated with the following command.

sudo sh -c "echo 20 > /sys/kernel/mm/hugepages/hugepages-\ 2048kB/nr_hugepages"

Also, if you are using multiple PAC cards, you need to allocate more memory. 

thanks

Folks,

What was the solution to this issue? I am having the same problem. From this ticket, it is not clear how the issue got resolved?

Ofcourse, I am unable to run in sudo mode.

Dear User,

this server does not allow you to run "sudo".

If you need to install a dependency, please put it in your home directory.

* For autotools, you can do it with "./configure --prefix=~/my-path"

* For Python packages, use "pip install <package_name> --user" or create a Conda environment.
