【MYD-Y6ULX】上电开机，预装系统试用

上电开机：
没有lcd屏，只能用debug接口，通过usb ttl串口模块连接到电脑上：

电脑打开putty，我的是com3端口，115200，8n1，打开：

开发板通电，debug旁边的5v红色指示灯常亮，蓝色led心跳灯闪烁，串口有输出信息：

官方的预装的是Freescale i.MX Release Distro4.1.15-2.0.1系统，busybox轻量级的，相对小简单，系统占用cpu和memory也没多少：

----------------

Nand flash占用的比较多，预装的系统50多兆占用了25%，工控就是工控，没办法自己折腾：(15GB和479GB两个是我自己的盘，不是板子自带的)

这个是nand flash 的分区信息：

0是uboot分区，5兆大小

1是kernel分区，2是dtb，3是rootfs，单位都是KB

Cpu信息：

内存：

Modules：

手动加载了个modules：看样子应该是示例代码会用到这个modules

系统是这个版本；工具链比常用的版本高，奇怪的是：工具链也不是系统光盘上那个版本，这就有点意思了：(感觉有点乱，这样也好，两个我都可以不用，用我自己的，反正已经很乱也不差我多这一个)

接下来看看示例代码，首先搭建开发环境：

我的开发环境是这样的：我不用虚拟机，个人感觉虚拟机性能不好，用的linux服务器搭建的开发环境，此处省略1万字。自己随便搭，搭建起来能用就行

开发板：

Windows电脑上：

稍后看看示例代码：

<未完待续>
