Introduction to On-Chip RAM

On chip ram, often abbreviated OCRAM has been around since the earliest System on Chips(SoCs). In the beginning, on chip memory was relatively small and was primarily used by bootloaders and as simple scratch memory. On chip RAM has since evolved in terms of size, speed and features as SoCs became more complex to often

BASEplatform Support for Express Logic’s X-WARE IoT PLATFORM

We announced a few weeks ago support for the Express Logic ThreadX RTOS as well as the X-WARE IoT PLATFORM™ within our very own BASEplatform™. This article goes over some of the advantages of using JBLopen’s BASEplatform Board Support Packages (BSPs) and drivers along with Express Logic’s solution. What Is the BASEplatform The BASEplatform is

BASEplatform Bring-Up on the Toradex Colibri iMX7

This article will go over some aspects of the early bring-up experience using the BASEplatform™ on the Toradex Colibri iMX7 System on Module (SoM). It will also cover features and advantages of the Colibri SoM for embedded developers interested in using an RTOS or a bare-metal environment on the NXP® i.MX7 SoC. The BASEplatform is

Estimating Worst Case Interrupt Latency at Runtime

In two previous articles we’ve explored interrupt latency on the ARM Cortex-A. While the numbers in those articles were generated using synthetic benchmarks, real application results are usually more useful. This article shows a simple way of estimating worst case interrupt latency at runtime which can be implemented on most MCUs and RTOSes or even

BASEplatform in Depth: The I/O API

In the last article about our recently launched BASEplatform product, we gave an overview of the various modules that can be part of the BASEplatform. In this article we go in a little more detail about an important aspect of any embedded software product, the API. In this case, the I/O API since it’s one

BASEplatform in Depth: The Modules

Two weeks ago, we launched our first embedded software product, BASEplatform. This article is the first of a series where we go into more details about the features and advantages of the BASEplatform. BASEplatform is designed to bring application developers all the necessary low-level components such as startup code, drivers, BSP, RTOS integration as well

Introducing BASEplatform

We are proud to announce that we are jumping in the embedded software component market with the introduction of BASEplatform™. Tackling the fundamentals, BASEplatform is a collection of low-level interface modules, drivers, and board support packages. Designed from the ground up to provide the foundation of a successful embedded software design. Whether for a bare-metal project

Zynq-7000 connectivity using the uC/OS BSP

In two previous articles, I have looked at using Micrium’s uC/OS RTOS on the Xilinx Zynq-7000. I only covered kernel and storage. This time, I will be exploring some connectivity options in combination with the Digilent Zybo. Namely, using Micrium’s USB device solution and HTTP server through the Zybo’s Ethernet port. This is also a

i.MX7D M4 Bare-Metal Bring-up and Benchmark

Following up on the last piece about the NXP i.MX 7, this article looks at the Cortex-M4 companion of the A7 present in the i.MX 7. Or to put it another way, a Kinetis-on-chip since it’s very similar to a high-end Cortex-M4 based Kinetis. This article summarizes my experience writing a brand new bare metal

i.MX7D Sabre Bare-Metal Bring-up and Benchmark

One of our specialities at JBLopen is board bring-up, either for bare metal or various commercial and open source RTOSes. Despite the number of different platforms, CPU architectures and RTOSes out there, low level bring-up, BSP and driver development are rarely discussed in blogs and articles on the web. While this is hardly my first

Improving Interrupt Latency on the Cortex-A9

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 bits ARM processors such as the

ARM Cortex-A Interrupt Latency

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.
