1Building Systems:The Migration Costs of the Warring States Period Fragmentation of Multiple Tools CMake/Bazel/Meson are in a three-way standoff: Syntax differences require relearning configuration logic for cross-project collaboration (e.g., CMake’s <span>target_link_libraries</span> conflicts with Bazel’s <span>deps</span> rule). Historical baggage hampers modernization: Legacy projects depend on Autotools-generated <span>configure</span> scripts, which have poor compatibility with modern IDEs (like … Read more
Course 1: Stage 1 – Basic Preparation (Week 1) Topic: Bare-metal program development, PL011 UART communication, ARMv8 boot process 1.1 Basics of Bare-metal Programming Core Concepts: Bare-metal Program: Runs directly on hardware without operating system support. Boot Process: The CPU starts executing instructions from the reset address (usually <span>0x0</span> or <span>0x8000</span>). Hardware (such as memory … Read more
Currently, most industrial control systems are embedded systems (a few simple systems use bare metal development directly). An “embedded system” refers to a computer system with specific functions embedded within specific hardware. Embedded systems generally consist of a real-time operating system (RTOS) + application software (a PLC itself is also an embedded system). Common real-time … Read more
