Error installing ATG drives

Question

Hello,  
I'm trying to run Using-PCIM-Port example from https://github.com/awslabs/aws-fpga-app-notes/tree/master/Using-PCIM-Port  
  
Following the read me, I was able to Load AFI, (agfi-0d132ece5c8010bf7) build ATG drivers and by the time I install I hit on a Error   
  
sudo insmod atg_driver.ko slot=0x0f  
insmod: ERROR: could not insert module atg_driver.ko: Device or resource busy.   
  
dmesg logs:

How can I fix this ?  
I'm using a x16 card on centos.

Answer

Hi TJ25,  
  
Could you check if xdma is inserted at this point?

```
lsmod | grep xdma
```

If it is, try removing it and you should be able to insert the atg driver.

```
sudo rmmod xdma;
sudo insmod atg_driver.ko slot=0x0f;
```
