    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?

      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.
