【AM335x】为 SD 卡创建分区的过程
首先，我用的是 VirtualBox，将 SD 卡放到 USB Adapter 之后，安装完驱动。即可执行 bin 下的 creat-sdcard.sh 脚本.
simon@simon-laptop:~/Work/ti-sdk-am335x-evm-05.04.01.00/bin$ sudo ./create-sdcard.sh
################################################################################
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
Formatting can be skipped if the SD card is already formatted and
partitioned properly.

Would you like to re-partition the drive anyways [y/n] : y
Now partitioning sdb ...
################################################################################
Select 2 partitions if only need boot and rootfs (most users)
Select 3 partitions if need SDK & CCS on SD card. This is usually used
by device manufacturers with access to partition tarballs.
****WARNING**** continuing will erase all data on sdb

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)
