Hi Parted Experts,

I am working on am335x based board.
We are using eMMC and as a storage medium and parted for partitioning eMMC.

I am not able to use "optimal" alignment option with parted when partitioni=
ng eMMC.
I get following error messages when I use "optimal" alignment

Warning: The resulting partition is not properly aligned for best performan=
ce.
Warning: The resulting partition is not properly aligned for best performan=
ce.
Warning: The resulting partition is not properly aligned for best performan=
ce.

1. Do we have to worry about this message ?

I have put question on Unix & Linux Stackexchange also below is the link fo=
r the same
http://unix.stackexchange.com/questions/248939/how-to-achieve-optimal-align=
ment-for-emmc-partition

Now parted reports logical and physical sector size as same.
"Sector size (logical/physical): 512B/512B"

2. Now my question is, is physical size reported by parted is physical sect=
or size or emulated physical sector size?
3.  How can we achieve optimal alignment ? Any suggestions?

Thank you,

Regards,
Ankur
