器件型号：OMAP-L138 主题中讨论的其他器件：OMAPL138、
我使用的是 OMAPL138处理器板。 我有2个不同的板。 图中显示了第一块电路板的电路
图 中显示了次级板的电路
我通过 UART2接口引导两个电路板上的处理器 OMAP-L138_FlashAndBootUtils_2_40实用程序。 我将*。AIS 文件引导至 NAND 闪存。 我 从 https://sourceforge.net/projects/dvflashutils/files/OMAP-L138/v2.40/下载 OMAP-L138_FlashAndBootUtils_2_40实用程序。
Furser、我将 BOOT 引脚设置为 UART2引导模式。 我在控制台中输入用于擦除 NAND 闪存的命令：sfh_OMAP-L138.exe -erase -targettype OMAP-L138 -flashType NAND -p COM4 -v.
我在第一块板的控制台日志中看到

Furser、我在第二块电路板上用示波器 NAND 端口引脚进行了查看、但 没有查看 NAND 闪存的时序图。 NAND 的所有处理器引脚被设定为3.3V。 但是、我在示波器上查看第一块电路板的正确时序图。
问题是什么？
