XRT ERROR : failed to load xclbin : input output error hello_world tutorial on AWS F1 / AMI 1.12.2

Question

I encountered an error during the official tutorial. (https://github.com/aws/aws-fpga/blob/master/Vitis/README.md)

I followed the tutorial in

AWS F1(f1.2xlarge) instance / oregon

FPGA Developer AMI - 1.12.2-40257ab5-6688-4c95-97d1-e251a40fd1fc ( latest )

AMI version : 1.12.2

Xilinx version : 2021.2

I ran ( $ source vitis_setup.sh source vitis_runtime_setup.sh ) and
checked Building the host application, Xilinx FPGA binary
and AFI creation completes successfully.

But when i run the cmd below

```
$ ./hello_world vadd.awsxclbin
```

It gave the following error
![Enter image description here](/media/postImages/original/IMvHWNC9gVTOKBmlE6lknzbA)

result of xbutil validate
![Enter image description here](/media/postImages/original/IMzskbmBjLQVKwqEUFJlJMHQ)

failed to find /opt/xilinx/das ...

Can you give me a solution for this situation?

Accepted Answer

I solved this problem my self.
I moved the region of f1 server from Oregan(us-west-2) to Virginia(us-east-1)
and used s3 bucket (us-east-1a Virginia).
After that i follwed procedure exactly when i tried before.

I suspect there's something problem with Oregon server

Answer

I believe `xbutil validate` tries to run a 'hello world' test utilizing a .xclbin rather than the .awsxclbin that is needed for the F1 instances, and therefore cannot complete the test.

After you run `vitis_runtime_setup.sh`, do you get any error messaging? Try to run the following and see what they return:

`xbutil examine -d 0000:00:1d.0`

`systemctl status mpd`

Also could you show the `dmesg` log?

Answer

There are only warning msgs when i run vitis_runtime_setup.sh. 
![result of vitis_runtime_setup.sh](/media/postImages/original/IMLHE2ueJDTdeCmPsID_iJ8Q)

```
$ ./hello_world vadd.awsxclbin
```
Results after executing the above code.

```
xbutil examine -d 0000:00:1d.0
```

![xbutil examine](/media/postImages/original/IMw66VAYeWTQSIAnUdnldMsA)

```
systemctl status mpd
```
![mpd status](/media/postImages/original/IMPDsVAdLxSgyA913exz7z0w)

and lastly the dmesg is here
