MicroBlaze Configuration for an RTOS Part 1 - Memory Hierarchy

MicroBlaze Configuration for an RTOS Part 1 – Memory Hierarchy

This is part 1 of a series of articles discussing the configuration of the Xilinx MicroBlaze when targeting an RTOS application. This series will focus on the software aspect of the MicroBlaze configuration. However, before tackling the numerous configuration options available to the MicroBlaze, it is necessary to introduce the various memory hierarchies possible with a MicroBlaze design. If you ...

Introduction to On-Chip RAM

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 include error detection and correction, ... Read more
BASEplatform Support for Express Logic's X-WARE IoT PLATFORM

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 a collection of embedded software ... Read more

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 a collection of embedded software ... Read more
Interrupt Latency

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 bare-metal. All that is needed ... Read more
BASEplatform in Depth: The I/O API

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 of the primary reasons to ... Read more
BASEplatform in Depth: The Modules

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 as toolchain support files and ...

Introducing BASEplatform

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 or with your choice of ... Read more
Zynq-7000 connectivity using the uC/OS BSP

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 perfect opportunity to try the ... Read more
i.MX7D M4 Bare-Metal Bring-up and Benchmark

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 bring up for the i.MX ... Read more
