Section 5.10 in the SRM Rev C.1 recommends using the power button to
power down the board and prevent contamination of the SD card or the
eMMC. This section gives a brief explanation of why also.

Hi Gerald,
Following the instructions on the BeagleBoard.org - getting-started
<http://beagleboard.org/getting-started> webpage, my team lead and I
have been powering up the BBB by using the provided USB cable to plug
our Beagle into our computers. We didn't find instructions on
powering it down. So, we have been powering it down by simply pulling
the cable out. By doing this, can we also get corruption? If so,
where is the shutdown procedure documented?

Nope. If you do it the way I just said, the board is powered off
after it is done. Then you can pull the power.
Pull the power without letting the kernel unmount the eMMC or SD
card, and you can get corruption.

So pulling out the power with properly shutting down the
system could corrupt the eMMC ???

Hi,
I am trying to use the beaglebone black (in factory
default settings) in a control application, where the BBB
interfaces to a 20x4 character LCD, 18 button keypad, and
a RS 232 connection using ttyO4 port (connects to RS 485
network using appropriate drivers).
I have almost developed the hardware and the software
using Eclispe C++ IDE.
As I am not using any batteries or other power backup
devices for the BBB, Do I have to implement a shutdown
procedure for my users ??
I have made a procedure in which the user presses a
combination of keys to get the shutdown option on the LCD,
selecting the shutdown option runs the system("shutdown -h
now") command in my C++ program.
Is a shutdown procedure required for the BBB or will just
pulling out the +5V power jack be sufficient.
I have read in some sites that the eMMC could get
corrupted causing startup issues....
Please advise....
thanks
