1、NandFlash烧录问题待解决样板没有烧程序，在上电后用示波器看NandFlash的控制输入脚，看到的波形如下：7脚 R/B# ：高电平3.3V19脚WP#：0V16脚 CLE :0V8 脚 RE#9脚：CE# 17脚ALE的波形18脚：WE#的波形各信号引脚及封装的说明：（连接的电路图在本文档附录中）下面是我用Flash V1.6.0.0的烧录过程：烧录下载都没出错，可惜从串口出来的是40x,xload引导界面并没有出来，我也再次用示波器看了一下输入脚的波形，请专家帮我分析分析，是哪出了问题。下面是我所做的过程。软件：Flash v1.6.0.0NandFlash：MT29F2G16，大小
