Click the blue text above Follow us! Microcontrollers (MCUs) in embedded systems are like the air traffic control systems of a busy airport. With modern MCU product lines, designers can add new features without increasing costs or reduce costs while maintaining existing feature sets, all while developing scalable software that can be reused in future … Read more
In previous articles, we often mentioned Armv8-A. So what exactly is Armv8-A? This question can be simple or complex. Today, let’s take some time to briefly study it. As we all know, ARM is a company that designs and licenses processors and corresponding IPs (such as interconnect buses, interrupt controllers, image processors, etc.). Currently, its … Read more
The ARM Cortex-M series is a low-power, high-efficiency processor architecture launched by ARM, mainly used in embedded systems, especially in Internet of Things (IoT) devices, smart homes, sensors, wearables, and more. The design goal of the Cortex-M series processors is to provide low power consumption and a simple architecture to support real-time operations while maintaining … Read more
Ozone is a multi-platform debugging and analysis tool for J-link and J-Trace. It features an independent graphical interface that can load Elf/Dwarf executable files generated by toolchains such as IAR, Keil, Gcc, and Clang/LLVM for C/C++ source code debugging and assembly instruction debugging. You can directly use the built-in functionalities of J-Link and J-Trace, such … Read more
Ozone is a cross-platform code debugging software that supports J-Link and J-Trace debuggers. It can load Elf/Dwarf executable files generated by toolchains like SES, Keil, GCC, and clang/LLVM for debugging C/C++ source code and assembly instructions. In the new version of Ozone, a debugging snapshot feature has been added, which can save the entire system … Read more
0. Introduction The documentation from ARM is already very good, but it still lacks clarity on what to do immediately after powering on, which caused me some trouble during my first use. Today, I will provide a detailed overview to help more friends. By the way, the ARM_Cortex-M0/3 DesignStart series will continue to be updated, … Read more
