microblaze的中斷 |
| 作者：coyoo 欄目：EDA技術(shù) |
外部中斷調(diào)試，程序執(zhí)行到microblaze_enable_interrupt()就停止了，不知道什么原因？！ 下面是我的主函數(shù)： /******************************************************************** * File NAME: main.c * Version: 1.0 * Date: 10/19/2003 * MODEL: Insight_MB_OPB_INTC * * Company: XILINX.html">XILINX * * Disclaimer: THESE DESIGNS ARE PROVIDED "AS IS" WITH NO WARRANTY * WHATSOEVER AND XILINX SPECIFICALLY DISCLAIMS ANY * IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR * A PARTICULAR PURPOSE, OR AGAINST INFRINGEMENT. * * COPYRIGHT (c) 2001 XILINX.html">XILINX, Inc. * All rights reserved **********************************************************************/ /******************************************************************** * This program uses the timer and gpio to demonstrate interrupt HANDLING. * The timer is set to interrupt regularly.

re 你的中斷句柄呢？把你的中斷處理程序貼出來。 |
