嵌入式Linux--MYS-6ULX-IOT--新板子上电串口打印信息
目录
- 一、上电输出
一、上电输出
可以使用的软件：
- SecureCRT
- MobaXterm (推荐)
开发板与计算机连接
- 计算机使用USB转TTL串口转接线与开发板的DEBUG串口(JP1)连接
- 运行串口调试应用程序，并选择对应的串口设备
计算机端的串口配置参数如下：
- 波特率：115200
- 数据位: 8bit
- 校验方式：None
- 停止位：1bit
- 流控：Disable
开发板登录名是 root，无需密码
在串口看到“mys6ull14x14 login:”时，输入“root”并回车即可
