基于MPC7410处理器的VxWorks系统板的研制
|
摘要
为满足后续新机含VxWorks系统的PowerPC处理器板深修的需要,基于MPC7410这款PowerPC处理器,研制一块具有串口、网口、SDRAM以及Flash的VxWorks系统板,在对该板功能进行系统阐述的基础上,给出其硬件架构与各部分电路设计,并在Tomado2.2环境下,开发BSP包,给出其硬件设计与软件开发过程中需要注意的方面,最后对其进行测试,测试结果表明其有效性。所研制的VxWorks系统板能够为后续新机带VxWorks系统的PowerPC处理器板的测试与修理提供技术支撑。
A motherboard that could run VxWorks operating system was developed based on MPC7410 processor with architecture of PowerPC. The board includes serial port, network port, SDRAM and Flash, which can meet the repair requirements of the VxWorks operating system board on the new aircraft. According to the systematic explanation on the function of the circuit board, the hardware architecture and circuit design of each part and BSP development in Tornado2. 2 were described. The difficulties in the circuit board hardware design and software development process were concluded. In the end, the board was tested and the result showed its effectiveness. The developed circuit board can provide technical support for the testing and repair of the PowerPC processor board with VxWorks operating system on new aircraft.
