The JLINK driver is installed, and the device manager recognizes it, but the options for SW and JTAG in MDK are grayed out (this is not an issue with JLINK). Therefore, downloading and simulation cannot proceed. I tried uninstalling the JLINK driver and re-installing it, but that didn’t solve the issue, so I decided to … Read more
We all know that autonomous driving is the future of automotive development. However, there has been much debate in the industry about when fully autonomous driving will be realized. In the meantime, advanced driver assistance systems (ADAS) have become a viable option under current technological and regulatory conditions. Many ADAS functions are already in mass … Read more
ADAS stands for Advanced Driver Assistance System, which translates to 高级驾驶辅助系统 in Chinese. Simply put, it actively makes judgments and preventive measures before the driver’s subjective reaction in emergency situations to achieve preventive and assistive effects. We can refer to it as a simplified version of autonomous driving—ADAS advanced driver assistance system. ADAS is not … Read more

Three important concepts in the Linux device model are bus, device, and driver. That is, bus, device, driver, and in fact, the kernel defines some data structures such as struct bus_type, struct device, and struct device_driver. These three important data structures come from one place, include/linux/device.h. We know that there are many types of buses, … Read more
