AM335x Beaglebone Black eMMC烧写记录

大家好，

最近在AM335x BeagleBone Black 上完整验证了下eMMC的烧写，总结了一篇文档共享出来，欢迎拍砖。

附件是文档中所描述的debrick.sh，烧写用的文件系统在后面的跟帖，这篇帖子可以和“AM335x Flash Tool — UniFlash 烧写工具使用简介及问题解决方案汇总”互为参考。

Jian Zhou：

不好意思，忘了加文档，这个跟帖是文档

这个跟帖是烧写用的文件系统

Jian Zhou 您好，我在用uniflash 通过USB下载时，每次下载到27%就停止，然后网路断开–>重连–>断开，之后设备管理器里USB/RNDIS网络就掉了。

请问这是什么原因造成的？谢谢

第二阶段要重新建立一个USB RNDIS连接，因此要在PC机重新设定一个USB 网卡。

可以参考http://processors.wiki.ti.com/index.php/Sitara_Uniflash_Quick_Start_Guide#Flashing_a_Board_using_USB中的第28节的说明

按照Uniflash guide所述，PC机上前后会出现2个网卡，这2个网卡都要设为192.168.100.1，不知道你有没有做这一步
