Paid open source contributors wanted! mentors contributors in 2024 Google Summer of Code Google just announced will be a mentoring organization for GSoC 2024. That means it is time for everyone to have some fun writing code. We’ve revamped our GSoC site in hopes to make it easier for students and mentors to learn about the program and […]

GSoC reaching first evaluation

Now is a great time to check out some of the on-going projects!

Using the U-Boot Extension Board Manager – BeagleBone Boards Example

This article follows two earlier blog posts about Device Tree overlays: Using Device Tree Overlays, example on BeagleBone boards Device Tree: Supporting Similar Boards – The BeagleBone Example Introduction As explained in the first two blog posts, the BeagleBone boards are supported by a wide number of extension boards, called capes. When such a cape […]

Device Tree: Supporting Similar Boards – The BeagleBone Example

Most of the BeagleBone boards from share the same form factor, have the same headers and therefore can accept the same extension boards, also known as capes in the BeagleBoard world. Of course, a careful PCB design was necessary to make this possible. This must have been relatively easy with the early models (BeagleBone […]

Using Device Tree Overlays, example on BeagleBone Cape add-on boards BeagleBone Relay Cape

The concept of Device Tree overlays The Device Tree language is a way to describe hardware that is present in a system and cannot be automatically detected. That’s the case of devices directly implemented on a System on a Chip, such as serial ports, Ethernet or Nand flash controllers. That’s also the case of devices […]

Improving usage of device trees

Using device trees is one of the most complicated and important, and sometimes risky, elements of using a Beagle to make use of add-on hardware. With the addition of the AM5729-based BeagleBone AI to the family of boards sporting BeagleBone headers, the complications have increased, requiring additional considerations with dependencies on different processor pins connected […]

Device Tree Overlay Support Lands Upstream

Pantelis Antoniou originated device tree overlay support for the purpose of enabling dynamic hardware configuration under Linux on devices like BeagleBone that use device tree for hardware configuration. Device tree was introduced to Linux for the purpose of putting the description of hardware into data structures, rather than building it up programmatically, greatly reducing the […]
