VP FPGA Error: "modprobe: ERROR: could not insert 'edma_drv': Exec format error"

[Hassan313]

I am following steps of 3.4.2 Setup AWS SDK and edma driver of the below link:

http://nvdla.org/vp_fpga.html

I get the below error:

[centos@ip-172-31-68-107 edma]$ sudo modprobe edma-drv
modprobe: ERROR: could not insert 'edma_drv': Exec format error

If I run the below command, the error goes away:

sudo rmmod xocl

Is the above command the right thing to do? Anybody can help me?

Thank you.

I'v already created a new AWS instance(based on AMI - ubuntu/images/hvm-ssd/ubuntu-trusty-14.04-amd64-server-20180308 (ami-38708b45)) to flush the flow. I do not meet such a issue. Please make sure you have already installed AWS SDK and move the driver to the right place.

[taog2018]

What's more, we need to make sure we are using the right AMI and AWS instance
Choose an Amazon Machine Image (AMI): we recommend the “nvdla_vp_fpga_ami_ubuntu”

Choose an instance type: we recommend the “f1.2xlarge”.

I am using the other AMI recommendation which the http://nvdla.org/vp_fpga.html has stated:

FPGA Developer AMI” (CentOS)

You are saying the SDK will not be installed properly on this type?

I followed the instructions stated all in the below image one by one:

Should I do something else to make the SDK to be installed?

[taog2018]

Not sure, I do not tried this AMI.

[Hassan313]

Not sure, I do not tried this AMI.

Sure, I will go with the same instance as you said shortly (in an hour).

Thank you very much.

@taog2018

So I should not checkout the version v1.4.0 of the aws-fpga? Because in the below image it is saying that we have to go with version 1.4.0.

Yes, we need v1.4.0

so there is nothing I have to follow from the below link;

https://github.com/aws/aws-fpga/tree/master/sdk

I have to follow the instructions in the below image:

Am I right?

@taog2018

I just ran the command setup sdk_setup.sh

It is saying the below:

Build complete.

Root privileges are required to install. You may be asked for your password...
Executing as root...

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin

AWS FPGA: Done with Amazon FPGA Image (AFI) Management Tools install.

INFO: sdk_setup.sh PASSED

Moreover, the lsmod | grep edma is not showing anything. It means I have to follow the next steps. Am I right?

[Hassan313]

@taog2018 When I follow the next steps, I get the following error:

ubuntu@ip-172-31-69-50:~/aws-fpga/sdk/linux_kernel_drivers/edma$ echo 'edma' | sudo tee --append /etc/modules-load.d/edma.conf
tee: /etc/modules-load.d/edma.conf: No such file or directory
edma

@taog2018 When I follow the next steps, I get the following error:

edma

Yes, you can create this path /etc/modules-load.d

Dear @taog2018 ,

Thank you for your help. I was able to successfully do "make" and "make install". The VP is up now.

Thank you very much again.
