ChatGPT’s take on SEGGER J-Links: An insightful “conversation”

Written by Bianca Schmidt on .

At SEGGER, we strive to deliver products that make developers go, “Wow!” SEGGER’s J-Link debug probes have an excellent reputation in the embedded industry – the real world full of real people. However, we were still curious to hear what the ever-growing artificial world had to say, so we asked ChatGPT about our market-leading devices.

The “conversation” with ChatGPT

The short answer was informative, enlightening, and very positive!

Me: What do you think of SEGGER debug probes?

ChatGPT: SEGGER debug probes are highly regarded in the embedded systems development community. They are known for their reliability, performance, and feature-richness. (more…)

Debugging with external memory: J-Link adds Dual Memory Maps

Written by Martin Baldwin on .

J-Link debug probes do two important things: they download programs into RAM or flash memory, and they enable debugging in real time, with the setting of unlimited breakpoints, viewing of memory registers, and much more. Without this debugging ability, we are back to trial and error. When the debug process just stops, with no way […]

Automated testing made easy with emSim

Written by David Noverraz on .

Software testing, for embedded or for native solutions, can seem like a headache, but it doesn’t have to be! Of course, there are challenges. Time and resource limitations can restrict the level of testing, and it is difficult to simulate all real-world scenarios and corner cases. This can lead to defects being found in the […]

A whole new way to interact with headless devices

Written by David Noverraz on .

We are relying more and more on wearable and connected technology, but how do we configure them without a human interface? A great example are the wireless headsets we now all use for video conferencing (thank you, Covid). The initial set up of the minimal devices can be challenging, holding buttons in what can sometimes […]

RISC-V: Dividing efficiently across different hardware

Written by Paul Curtis on .

In previous blog posts I have described the division algorithms SEGGER implemented in emRun. However, which algorithm is best (in terms of code size, execution speed, or power efficiency) is very dependent on the target instruction set architecture (ISA) and the way the ISA is implemented in silicon. This article explains how we help to […]

Size matters – Comparing tool chains and CPUs

Written by Rolf Segger on .

Many people think that in today’s world, the size of a program does not matter. In many cases, that is not true, especially in the world of embedded computing systems. I explain why and introduce a benchmark that makes it possible to easily compare the code-size efficiency of different tool chains (Compiler, assembler, linker, run […]

C++ pitfalls – Memory allocation from interrupts

Written by Rolf Segger on .

Modern C++ programming very much abstracts what is happening “under the hood” – i.e. what code the CPU is actually executing. This is nice for the programmer … if it works well. Unfortunately, C++ also introduces a stability problem in embedded systems. Many programmers are unaware of this problem. This post gives some background, explains […]

Securing embedded systems with digital signatures: The basics

Written by Martin Baldwin on .

Securing an embedded system is incredibly important, and having a digital signature plays a crucial role in that. A digital signature confirms that a specific piece of information came from a specific organization (i.e. the one with the private key as described below) and has not been modified. Follow-up articles will firstly cover related issues […]
