Buildroot is a tool that simplifies and automates the process of building a complete Linux system for embedded systems using cross-compilation. To achieve this, Buildroot can generate a cross-compilation toolchain, root filesystem, Linux kernel image, and bootloader for your target machine.Buildroot can be used independently for any combination of these options (for example, you can … Read more
Robots are not isolated systems; they are a set of distributed sensors and actuators, often running on resource-constrained small embedded devices (microcontrollers) that communicate via wired or wireless connections. However, mainstream robotic operating systems like ROS/ROS2 are too large and heavy, making them unsuitable for robotic scenarios based on microcontrollers with hard real-time requirements. Zephyr … Read more
