我安装的SDK是PROCESSOR-SDK-RTOS-AM335X 02_00_00_00版本。 开发环境是在ubuntu14.04 64位系统上的。
同时为了验证对比，我也安装了个linux的SDK，版本是：PROCESSOR-SDK-LINUX-AM335X 02_00_00_00。
然后同样的一张SD卡，我用SDK-LINUX安装目录下的 bin/create-sdcard.sh脚本，可以制作出SD卡，并且放到开发板上能够开机。
但当我用SDK-RTOS 安装目录下的/processor_sdk_rtos_am335x_2_00_00/bin/create-sdcard.sh脚本做卡时，提示我选择要做的SD卡后，两三秒内就运行结束，卡也没做好。log如下：麻烦帮我看看是什么原因。

This script will create a bootable SD card from custom or pre-built binaries.
The script must be run with root permissions and from the bin directory of
the SDK
Example:
$ sudo ./create-sdcard.sh path/to/sdcard/files
Formatting can be skipped if the SD card is already formatted and
partitioned properly.
