Welcome Jason Kridner (@Jadon) and Robert Nelson of the Beagleboard.org board!
- Jason was one of our first guests on TAH, episode 59!
- The original Beagleboard ran angstrom and Maimo (sp?)
- Users of the Nokia N900 helped to port to the processor platform.
- Golden delicious – open moko
- Beagle x15
- Device tree
- Where (and how) to start building your own images: on an x15 because it’s fast
- Yocto project
- Pocket Beagle. Chris complained about the headers for the pocketbeagle.
- The new SIP is from Octavo.
- Tom Bewley from UCSD teaches a course using the BeagleBone blue. It runs Ardupilot and other robot/drone software out of the box
- Ken Shirriff’s episode
- A memory management unit is usually the delimitation between embedded and full blown linux
- PRUs – programmable realtime unit
- BeagleLogic – Sigrok
- 3.8 is the most used kernel

- where to get support
Patrick Woodlock says
What a awesome espisode. Although it took a few goes to fully finish it while I was walking.
Regarding Ken Shiriff’s tutorial, is it this?
Regarding the PRU, anyone know if it’s possible to do real-time if/else based on the i/o status read? Something like the GX5296, tabor elec 5251, etc?
Matthijs van Duin says
Ben: What do you mean exactly? The PRU cores are still just processors, there’s no FPGA/CPLD-like direct coupling from input to output possible. However, the predictable instruction timing combined with having I/O wired directly into registers make it possible to have outputs react to inputs with absolutely deterministic timing.
Awesome questions Chris. They were right up there with the ones i wanted to ask. Great episode
The spelling you were looking for is “Maemo”. That was around the time of Intel’s Moblin (mobile Linux?) and stuff. They then combined and that didn’t survive either… 🙁
Exellent episode. I listened to it twice on a plane trip and the second listen really helped me understand the layers within linux. This episode got me to think of many questions that I would not have had otherwise. Spending a few hours online researching these questions has put me in a great place of understanding and improved skills. THANK YOU.
