AM3352与AM3359区别

Other Parts Discussed in Thread: AM3352, AM3359

      之前代理商给的样片是AM3359,在我们自己的开发板上工作正常。后面给的样片是AM3352,使用串口启动方式准备下载程序时发现,串口输出变成0xC1而不是 之前的0X43(字母C)。用示波器测试发现,串口输出的波特率变了。

      请问:1. AM3352与AM3359在启动配置、外部时钟上有什么区别?

                   2. 什么原因可能导致串口启动时,波特率配置出现偏差?

     说明:我的开发板上外部时钟是24Mhz,LCD_DATA15, 14的配置(1,0)也没有问题。
