AM335x Beaglebone Black eMMC烧写记录

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

串口信息如下：

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

设定过了 

谢谢 确定是按照文档内容进行的设定

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

如果要从eMMC启动，要查一下eMMC芯片是用的什么协议，如果是v4.41以下的要接在MMC0接口，v4.41以上的都要接在MMC1。

Jian Zhou您好:
请问sdk7.0的emmc flash验证了吗？我按照贵公司给的资料，始终不能成功，log如下，请问能帮我解答下吗？

你好：
我使用debrick.sh脚本从SD卡烧写eMMC时，系统启动后自动执行debrick.sh，总是cannot find boot_partition.tar.gz和rootfs_partition.tar.gz。
必须登陆后，手动执行debrick.sh才能成功。求助！！！

你好：
 我是用uniflash烧写的，不过以前也试过用T卡烧写过貌似和你一样的现象，不过dbrick.sh，貌似是烧写文件系统中的一个fether.sh这个脚本来调用的，你看看有没有这个脚本文件，还有权限问题也很重要。

需要更改下debrick.sh，将boot_partition.tar.gz和rootfs_partition.tar.gz存放位置的目录更新下

提示的错误：
tar：cannot open 'boot_partition.tar.gz':No such file or directory 
Command exited with non-zero status 1

但是我随即登陆后，发现rootfs_partition.tar.gz和boot_partition.tar.gz是存在的。然后手动执行debrick，就不再提示类似错误了，能够成功的烧写eMMC，并从eMMC启动。

有fetcher.sh脚本，它也有权限，就是执行过程中提示找不到rootfs_partition.tar.gz和boot_partition.tar.gz。而登陆后发现目录中是有这两个文件的，此时手动执行一次debrick.sh是可以成功的。

您好：
   我也在从T卡烧写到emmc的时候遇到了一点问题，明明已经烧进去了，拔掉T卡emmc里面是空的，而且T卡貌似也不能启动了，连续试了两个卡都是这样，请帮忙看看。log如下。
