How to Start openOCD on ARM M1 MacBook: A Step-by-Step Guide

If you're trying to get openOCD up and running on your ARM M1 MacBook and are facing difficulties, you're not alone. Many users have experienced issues, particularly when connecting development boards like the STM32F3 Discovery. In this guide, we'll explore common problems associated with starting openOCD and provide effective solutions to help you get connected and coding quickly.

Understanding the Problem

When you attempt to run the command to start openOCD with your STM32F3 Discovery board, you may see output similar to the following:

This error message indicates that openOCD is failing to initiate a proper connection to the attached board. This can be frustrating, especially if you're not sure what the underlying issue is.

Troubleshooting the Issue

After digging deeper into the problem, it was discovered that the most likely cause for the open failed error stems from the type of USB cable being used. Here are the steps to resolve this issue:

1. Check the USB Cable

Use a Data Cable: Ensure that you're using a mini USB cable that supports data transmission. Many cables are designed solely for charging or power and do not contain all four lines necessary for data communication.

Verify Connectivity: Look for indications that the cable is in good working order, such as a firm fit in both the MacBook and board ports.

2. Replace the Cable if Necessary

If you find that your current cable is not a data-capable cable, replace it with one that is. A proper mini USB cable should have the following configuration:

Power lines - Two wires for power.

Data lines - Two additional wires for data transmission.

3. Retest openOCD

Once you have a suitable cable connected, run the openOCD command again:

If everything is set up properly, openOCD should initialize without errors and allow you to connect to your STM32F3 Discovery board.

Conclusion

Setting up openOCD on your ARM M1 MacBook can be a challenge, but identifying the right hardware and ensuring that you’re using a compatible USB cable can make all the difference. By following these guidelines, you should be able to troubleshoot and successfully start openOCD with your development board.

If you continue to experience issues beyond changing the cable, consider consulting the openOCD documentation or community forums for additional support. Happy coding!
