Hi everyone!

I compiled the [hello world](https://github.com/Xilinx/Vitis_Accel_Examples/tree/master/hello_world) and [this other example](https://github.com/Xilinx/Vitis_Accel_Examples/tree/master/cpp_kernels/systolic_array) on an AWS instance with the FPGA Developer AMI and obtained the corresponding xclbin files.

When I try to download the xclbin file on an F1 instance, it fails with the following error:

```auto
import pynq

# program the device
ol = pynq.Overlay("vadd.xclbin")

---------------------------------------------------------------------------

    499 self.contexts = old_contexts
    500 raise RuntimeError("Programming Device failed: " +

    502 finally:
    503 xrt.xclUnlockDevice(self.handle)

RuntimeError: Programming Device failed: EINVAL (22) Invalid argument

```

Any hints? Am I missing something?

Thanks in advance,

Moving to support.  
Did you run the process to create an Amazon FPGA image (AFI), or is the xclbin the output of Vitis?

Hi Cathal,  
this is the xclbin from Vitis.

Do I need to create the AFI, the process with the S3 bucket?

Best,  
Medrano.

Yes, exactly, you need to create the AFI - this is the way AWS works.

This may be useful:

Thanks a lot.  
A final question, so, the file you should pass to pynq is the _awsxclbin_, as in

`ol = pynq.Overlay("vadd.awsxclbin")` ?

Best,

You can rename the awsxclbin to xclbin for Overlay class to accept it.

This isn’t necessary. Any filename extension will do.
