How do I obtain faasutil? - FPGA as a Service - Alibaba Cloud Documentation Center

faasutil is a next-generation command-line tool provided by Alibaba Cloud FPGA as a Service (FaaS) and can make FPGA-accelerated instances easier to use, and more stable, secure, and scalable. You can use faasutil to run simple commands to configure environments, and generate and load FPGA images without caring about the underlying implementation. This topic describes how to obtain faasutil.

Prerequisites

An FPGA-accelerated instance is created and connected by using a tool. For more information, see Connection method overview.

Procedure

Run the following command to check whether the /dev/virtio-ports/FaaS.agent file exists on the FPGA-accelerated instance:
```
ls -l /dev/virtio-ports/FaaS.agent
```
- If the file exists, go to the next step.
- If the file does not exist, the current FPGA-accelerated instance does not support faasutil. Use faascmd instead. For more information, see faascmd overview.

Run the following command to download faasutil:

wget https://fpga-tools.oss-cn-shanghai.aliyuncs.com/faascmd_bin/v2_0/faasutil

Run the following command to make faasutil executable:
```
chmod +x faasutil
```
