In this article I’ll explore interrupt latency of a Cortex-A9 under various scenarios, and yes it’s still on the Zynq-7000 since I still have that board on my desk from the last two articles. An upcoming follow-up article will describe methods of improving worst case latency.

Embedded Storage on the snickerdoodle
This is a continuation of the snickerdoodle adventure following last week’s successful “hello world” using Micrium’s µC/OS RTOS. In this series of articles, I’m exploring the capabilities of the snickerdoodle as a development platform for high performance real time operating systems. This time, I will be running an embedded file system on the snickerdoodle module, enabling non volatile storage capabilities. The bare snickerdoodle module includes an SD Card cage in addition to an on-board NOR flash. While possible to use the NOR flash, this post will focus on the SD Card which offers more versatility for development and prototyping.

snickerdoodle says Hello World!
What would make a better first post about embedded software than a hello world project on a brand-new development board. It’s the krtkl snickerdoodle I received with much excitement last week. In these next series of articles I’m going to explore the capabilities of the snickerdoodle as a development platform for high performance real time operating system. In this first article I’ll run µC/OS, a commercial RTOS, on the snickerdoodle.
Before going any further, I think it’s important to mention that the snickerdoodle with various optional base boards and accessories can still be pre-ordered from Crowd Supply. Expected shipping date is around August.
