摘　　要：基于μC/OS-Ⅱ系统的高可靠性启动引导程序,除完成板卡初始化、引导和启动μC/OS-Ⅱ系统外,特别加入了NorFlash CRC校验、内存和SRAM测试、故障记录等功能,极大地增加了板卡启动引导过程的可靠性。该方法已在实际产品中验证可行,并在铁路信号系统中得到了广泛应用。The high reliability boot program based on μC/OS-II system complete the board initialization, boot and start μC/OS-II system, in particular, joined the NorFlash CRC check, SDRAM and SRAM test, fault records and other functions. Greatly increasing the reliability of the board boot process. The method has been proved feasible in practical products and has been widely used in railway signal system.
