Imagine you’re just stepping into the world of embedded systems. Your possibilities as a developer are endless—from creating smart home devices to powering industrial automation. But with so many tools, technologies, and processes to learn, where do you even begin?

ChatGPT’s take on SEGGER J-Links: An insightful “conversation”
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. […]
J-Link PRO PoE powers the SEGGER test farm
We have been using automated tests on hardware in the Flasher and J-Link departments for some time. But now with the new J-Link PRO PoE, we felt it was time to get some of the evaluation boards out of the cabinets and build a proper test farm. We are selecting the most popular boards so […]
Debugging with external memory: J-Link adds Dual Memory Maps
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 […]
CPU Design at SEGGER
CPU design is not normally what we do. But: We actually have 2 CPU designed and in use, an 8-bit and a 32-bit CPU. In this article we look at our 32-bit CPU, or rather how we are creating an enhanced version of it with very high Code Density
RISC-V: Dividing efficiently across different hardware
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
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 […]
Hacking emSecure?
On October 24th of 2021, we were contacted by the Moscow based security company BI.ZONE Research Lab. BI.ZONE is a security research firm, checking software and computer systems for vulnerabilities. They were trying to find weaknesses in J-Link.
Correlating and visualizing data sampling, current consumption, and program execution via Ozone’s Timeline Window
SEGGER’s J-Trace PRO streaming trace probe and Ozone debugger make a great team. One highlight of this symbiotic relationship is the Timeline window. It allows users to correlate and visualize data sampling, current consumption, and program execution in one combined signal plot. This article takes a closer look at this functionality.
Every byte counts – Smallest “Hello world”
When searching on-line for small C-programs, there seems to be a lot of confusion about what is doable and what is not. There are a lot of posts wondering why even for minimal programs such as “Hello world” applications are so big, but not many explanations or fixes. I will show how to make a […]
