Embedded Software Insight
Continuing from the last post, this article explores features specific to early members of the ARM Cortex-A family such as the Cortex-A9. Namely the L2 cache and TLB lockdown features found in those processors. It’s important to note that those two features are not available in more recent 32 and 64 bits ARM processors such
In this article, I’ll explore the interrupt latency, also known as interrupt response time, of an ARM Cortex-A9 under various scenarios — and yes, it’s still on the Xilinx 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
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
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. The SoM is based on the Xilinx Zynq-7000 SoC along with storage and wifi on the SoM. In these next series of articles, I’m
