VxWorks 7 is a modern real-time operating system (RTOS) launched by Wind River, with significant improvements in the modularity and tool support of its BSP (Board Support Package) development process. The BSP serves as a bridge between hardware and the operating system, responsible for hardware initialization, device drivers, and system configuration. This article will detail … Read more
In embedded system development, developing device drivers is a crucial task. As a bridge connecting hardware and software, the quality of device drivers directly affects the correctness of system functions and the stability of operation. In the rapidly evolving open-source ecosystem, Zephyr RTOS is favored by developers for its lightweight, modular, and highly scalable features. … Read more
Overview VxWorks is a high-performance real-time operating system (RTOS) widely used in embedded systems that require high reliability and real-time performance. The Controller Area Network (CAN) is a common communication protocol in industrial control and automotive electronics. Combining CAN programming with VxWorks can achieve efficient communication and control systems. This article will introduce the basic … Read more

Hello everyone, in this article we will talk about a common communication protocol in embedded development – the SPI protocol. However, today we will not discuss its basic principles, but rather explore a detail that many may not have noticed: the 4-wire and 7-wire versions of the SPI protocol. You might wonder, isn’t SPI just … Read more

Introduction The development of UART has matured significantly, and it is generally sufficient to directly port the 8250 driver. For example, the UART driver for Rockchip directly uses “snps,dw-apb-uart”, which corresponds to <span>Linux-4.9.88/drivers/tty/serial/8250/8250_dw.c</span> driver. uart1: serial@ff190000 { compatible = "rockchip,rk3368-uart", "snps,dw-apb-uart"; reg = <0x0 0xff190000 0x0 0x100>; clock-frequency = <24000000>; clocks = <&cru SCLK_UART1>, <&cru … Read more
Issue 1: The driver cannot load or reports an error after loading. Possible reasons: Incorrect compilation options, module information, dependencies, symbol exports, etc.; the driver is incompatible with the kernel version; the driver is incompatible with the hardware device; errors in the driver’s initialization or exit functions; issues with the driver’s permissions or path settings, … Read more
