NandFlash引脚及用示波器看到的波形
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3.3V
19脚WP#:
0V
16脚CLE:
0V
8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FlashV1.6.0.0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:
Flashv1.6.0.0
NandFlash:
MT29F2G16,大小256M,16位,如下图所示:
