云联芯开源并赠送的NUC980板子学习过程记录(待续)

收到云联芯赠送的NUC980板子（活动链接： https://whycan.com/t_7473.html ），接口很丰富，板子也和整齐。在这里首先感谢观海和晕哥平台提供的机会。下面开始记录学习的过程。

原理图和PCB可以在上面的活动链接重找到。
新塘资料可以到下面的github及官网找到。
https://github.com/OpenNuvoton/MPU-Family

1.首先下载原理图，发现图纸上的PG0和PG1和板子接法不一致，后面发现板子是V1.2版本的，图纸是V1.1版本并确认引导方式是从nand引导。
2.给板子UART0的TTL串口外接232模块，接好后如下

3.连接好串口线，打开串口终端，设置115200 8 N 1,然后给板子加电，终端输出信息如下
