Manufacturing

We have placed an order for the initial batch of ctxLink components, and PCB fabrication and assembly will begin soon. Meanwhile, we have added support for re-flashing a known working firmware in the unlikely event that you brick your ctxLink. Finally, we decided to keep ctxLink at $99 for pre-order.

A Sincere Thank You to Our Backers

With the initial stage of funding behind us, we would like to take this opportunity to thank each backer for their support and confidence. Over the next few weeks, in parallel with the startup of manufacturing, we will continue our work to add SWO support over the network and to merge the latest Black Magic Probe updates into ctxLink. Thanks again for joining us on this journey! Read the full update.

The Journey to Funding

This journey has been challenging at times, but always interesting. Our campaign comes to a close in just over 24 hours, and we thought revisiting that journey might be helpful for those who are still on the fence about backing ctxLink. Read the full update.

3D-Printable Cases

Bob Miller (@kbob) has produced not one but two ctxLink case designs. One is open, the other has a top cover, and both hold the battery securely beneath the ctxLink itself. Read the full update.

Extending a Target’s Serial Port

It is often valuable to be able to send messages from the target system when monitoring its state. Black Magic Probe (BMP) implements a USB serial port that performs this task. It provides a serial connection that you can attach to a UART of the target. BMP will then send the data it receives through this connection to a second USB serial port on the host computer. ctxLink now provides the same functionality, over the network, by exposing a separate TCP port to which client applications can connect in order to receive serial data from the target.

Wireless Debugging With Visual Studio Code

I have spent the past few days working to get ctxLink running with the highly extensible Visual Studio Code (VSCode) development environment. VSCode makes it quite straightforward to use a typical "makefile" project for ARM development. Read the full update.
