Running error for FPGA examples

Question

Hello!  
  
I'm trying to run some examples provided by AWS, in specific OpenCL examples (https://github.com/aws/aws-fpga/tree/master/SDAccel/examples) and I'm getting some errors in the execution part. (I try to execute in the FPGA itself, not any type of emulation)  
  
I followed and done every step guide, but when I try to do "./helloword *.awsxclbin" I receive an error message (below).

Answer

Hello,  
  
For Error 1:  
In this case you might want to run as root as it seems like your user does not have privileges to run.  
  
For Error 2:  
  
Try running the following commands:

```
sudo -E /bin/bash
source /sdaccel_runtime_setup.sh
./helloword *.awsxclbin
```

Also check that you have permissions to load the AFI that you created.  
To find out the AFI it is trying to load from the awsxclbin, run the following command:

```
cat vector_addition.hw.xilinx_aws-vu9p-f1-04261818_dynamic_5_0.awsxclbin | strings | grep AGFI
```

To see if you have permissions to load the AFI, try loading it manually:

```
cat *.awsxclbin | strings | grep agfi | xargs fpga-load-local-image -S0 -I 
```

This output should show something like:

```
AFI          0       agfi-096d0d8abcdefg  loaded            0        ok               0       0x04261818
AFIDEVICE    0       0x1d0f      0xf010      0000:00:1d.0
```

If it isn't loading, that means your account does not have permissions to load the AFI. You would have to use the modify image attribute from the account credentials you used to create the AFI to allow your other accounts to load it:   
  
Please feel free to let us know if this doesn't work.
