How to Run ARM Assembly (.s) Files on VSCode in Linux Subsystem

If you're new to ARM programming and trying to run your assembly files in Visual Studio Code (VSCode) on the Linux Subsystem, you're not alone. Many beginners face challenges when transitioning to ARM development, especially without a Raspberry Pi or other dedicated hardware. In this guide, we will guide you through a detailed walkthrough of running your assembly files in VSCode using the Linux Subsystem on Windows. Let’s dive in!

Introduction

Before we get started, let’s clarify what you need to accomplish. You should be able to run an ARM assembly (.s) file, specifically a file containing a simple division operation. Your file might look similar to the following example:

To run this in VSCode on the Linux Subsystem, you need to follow these steps:

Step 1: Install Necessary Tools

The first thing you need is the right tools and compilers to work with ARM assembly code. Here’s how to do that:

Install QEMU - QEMU helps emulate ARM architecture:

Step 2: Writing Your Assembly Code

Using VSCode, create a file named division.s. You can use the following example which performs a simple division:

Step 3: Compiling the Assembly Code

Once your assembly file is written, you need to compile it with ARM GCC. Run the following command in your terminal to compile the code:

Step 4: Running Your Compiled Code

Now that you've compiled your ARM assembly code, it's time to run it using QEMU. You can execute it in the WSL terminal like this:

The expected output for the division of 23 by 4 should be 5, indicating that your code works as intended.

Running from Windows 10

You can also run this code from your Windows 10 command prompt by using the following command:

Conclusion

Congratulations! You have successfully run ARM assembly code in VSCode using the Linux Subsystem. Remember, QEMU and the ARM GCC compiler are essential tools for emulating and compiling ARM architecture on your machine. If you encounter issues related to dynamic libraries in the future, consider using the -static option while compiling to avoid unnecessary complexity.
