Understanding Yocto Source Code MIRROR and AWS Storage Service In the Yocto Project, a MIRROR refers to an alternative repository that can be used to download source code. This allows the build system to download necessary sources from a specified mirror server or local storage first, without relying on external internet resources. It helps to improve build efficiency, conserve network bandwidth, and reduce the possibility of download failures.Key Features ..
Build Performance Improvement (Optimization) Last October, I wrote about optimizing Yocto build performance in a post on Yocto’s website and briefly mentioned some of the work we did at the company, such as applying clang and ccache. In this article, I aim to share insights based on my experience on improving build performance in embedded software development. This should provide a broad perspective on enhancing performance for builds invo..
Debugging Yocto Shared State Cache The shared state cache (SSTATE) in the Yocto Project is a mechanism used to increase the build speed and efficiency of the build system. This caching system allows for the reuse of previously built artifacts, so the entire build process does not have to be repeated every time. The above illustration explains Bazel’s Remote Cache, which is similar to Yocto’s Shared State Cache or PREMIRROR. These..
In SDV (Software-Defined Vehicle) development, HW/SW Decoupling SDV (Software-Defined Vehicle) is one of the most frequently heard terms in the automotive field. However, within the company, we don’t hear it as much during development. Internally, we use the term MB.OS (Mercedes-Benz Operating System) much more frequently. Nonetheless, it is clear that SDV is widely used in media and other company blogs. Despite this, I can’t help but feel that, like the ter..
QNX’s SDV Strategy: QNX Cabin Last Wednesday and Thursday, QNX visited our company for two days. One day was dedicated to a demo, and the other to a full-day technical workshop. I attended both days and would like to briefly share my thoughts on QNX’s SDV strategy. It was nice to see webOS again after such a long time. :)” In conclusion, if everything is implemented well as planned, OEMs using QNX will likely become less dep..
