WhyCan Forum(哇酷开发者社区)

前几天找了一下这款BeagleBone Black开发板，找着找着找到这玩意，买了2块回来，一块70元（带电源、原理图、补焊了USB），一块25元（缺usb外围原件）

CPU：AM3352
内存：256M
ROM： 256M NAND
百兆网口

跟中国版BeagleBone Black有什么区别？
1、阉割HDMI，保留RGB；
2、eMMC改为NAND，GPMC挂着NAND，GPMC挂并口设备爽啊！

我的用处：GPMC接口挂NAND和2片CH438 8串口芯片，一共16串口。
目标：
刷回原来的uboot以及内核，官方的SDK
挂上2片ch438，实现外挂16串口。
