The dilemma of shipping fast versus maintaining quality I'm not just talking about automotive software development. I think it applies to all development. However, it seems to be much more relevant in automotive software development, where dependencies and architecture are incredibly complex. Is it better to release the product quickly or to maintain the quality and solidify consumer trust? It's a difficult story. It's also easy to say. Put it in con..

Thoughts on building QNX with Yocto I'm using QNX as a SafeOS and the build system is a mess. What QNX provides by default is a simple Makefile + a qconfig.mk file with some QNX modifications. This is fine for small projects, but I was wondering what tools I could use to build better with better dependency and geometry management.We use a wrapped build system based on CMake and run in a Docker environment. The code is not all sour..
QNX and the QNX Build System QNX is a Real-Time Operating System (RTOS), based on a microkernel architecture and used primarily in embedded systems. QNX was developed by QNX Software Systems in Canada in the 1980s and is characterized by high reliability, real-time processing power, and small memory usage. Acquired by Blackberry in 2010, the QNX hypervisor is ASIL D certified and has many production references, making it a ..
AutomotiveMixed Criticality System Mixed Criticality is a concept used primarily in real-time embedded systems that addresses the issues that arise when tasks of different criticality are running simultaneously on the same system. This concept is especially talked about in safety-critical areas such as aircraft, automobiles, and medical equipment. Key Features1. Task's Criticality Level: Each task within a system has a specific c..
How to Debug Yocto Packages (oe-pkgdata-util) There are a variety of tools under the scripts directory in Poky, Yocto's reference. In this article, we'll see how to use the oe-pkgdata-util script to simply debug a package. Here is an example of what options are available as a result of using the help command. In this article, I'll walk you through the following commonly used commands and explain them briefly.list-pkgs: Print a list of packa..
The state of EVs and SDVs in China I traveled to Shanghai, China for a business trip and spent the whole day learning about Chinese EVs and SDV-related software, touching various cars and hearing about the trends from experts. It was very realizing to see and touch what I had only heard about. It was a great experience to compare with the cars we are currently building.In China, there are a lot of electric cars driving around, an..
