Runtime error on f1 instance: [XRT] ERROR: No devices found

0

Hi!

I am new to FPGA development, and I am working on a project with Vitis on an AWS instance. Both the host and kernel code is written in C/C++, and it successfully passed software and hardware emulations in Vitis.

For synthesis and emulations, I am using a c4.4xlarge instance with the FPGA Developer AMI - 1.8.1. After doing a system hardware build, creating an AFI, and waiting for the AFI to be available, I stop the c4.4xlarge instance, and changed it to a f1.2xlarge instance.

Then in the f1.2xlarge instance, I followed the steps in Link: https://github.com/aws/aws-fpga/blob/master/Vitis/README.md to source the vitis_runtime_setup.sh script, sourcing this script shows

INFO: XRT Runtime setup Done
INFO: XRT Install, non-dev
INFO: Starting MPD
INFO: Vitis runtime check PASSED

Then I do $ systemctl status mpd to check mpd status, and it shows

● mpd.service - Xilinx Management Proxy Daemon (MPD)
Loaded: loaded (/etc/systemd/system/mpd.service; disabled; vendor preset: dis abled)
Active: inactive (dead)

Then I execute the host code by doing ./host ./binary_container_1.awsxclbin. and the error arises:

Current working dir: /home/centos/Vitis-tutorial/aws-fpga/Vitis/tools
File opened successfully!
XRT build version: 2.3.0

[XRT] ERROR: No devices found
../src/xcl2.cpp:48 Error calling err = cl::Platform::get(&platforms), error code is: -1

I am not sure where the problem could be since I am using the latest version of the fpga developer AMI which should have the corresponding XRT pre-installed? Please let me know if more details should be provided, and thank you for reading through this post!

Any help is greatly appreciated!!

Thank you,

Owen

Hi Owen,

Are you by any chance running as 'centos'? To run the application, once mpd has started, you can check:

sudo systemctl status mpd

After that you can source the runtime setup script as root:

[centos@ip-172-31-39-217 aws-fpga]$ sudo -E /bin/bash

Hi Owen,

XRT is preinstalled on the FPGA Developer AMI.

It seems like MPD failed or did not start in this case. Could you run:

sudo systemctl start mpd
sudo systemctl status mpd

If it still isn't running, could you share the output of:

sudo journalctl -u mpd

That way we can get more information on why MPD failed to start. Also, what region are you running this in? For MPD, we have to load a default AFI to change the PCI Device ID that the driver binds to, so another thing to check is to see is the device id on the slot.

Thanks,

Deep

Hi Deep,

Thank you so much for your reply! I am running in us-east-1 region (N. Virginia). I tried the first two commands but mpd is still not running...

The output of

 $ sudo journalctl -u mpd

shows

 -- No entries --

Could you please let me know how I can check the device ID? I also tried starting another f1 instance (without changing from c4.4xlarge). On that instance, everything works fine: mpd starts successfully and the program runs successfully.

However, I would still prefer being able to change the c4.4xlarge instance to f1 instance to execute the program. This way I don't have to keep two copies of the EBS storage space... Please let me know if there is anything that I can do.

Thank you,

Owen

I am working on a project with Vitis on an AWS instance. I followed the instructions of helloworld lab in website: https://github.com/Xilinx/Vitis-AWS-F1-Developer-Labs/blob/master/modules/module_01/lab_01_vitis_env_setup.md

When I run "make run TARGET=hw", it showed: [XRT] ERROR: No devices found

It is because MPD wasn't started. I checked the status of MPD, it showed: ConditionDirectoryNotEmpty=/dev/xfpga was not met

It seems the same problem of this, but I cannot find how you resolved the problem of "ConditionDirectoryNotEmpty=/dev/xfpga was not met" and launched MPD successfully. Could you help me?
