Having trouble partitioning SD card

Hello, I currently just purchased an imx6q board and I'm trying to put Android 5.0.0 on it.  I'm running into some difficulties trying to partition the SD card.  When I run the mksdcard-android.sh on my SD card, I get the following errors ( I've made sure the card is unmounted (umount /dev/sdc) before I run the script):

 

1+0 records in

1+0 records out

1024 bytes (1.0 kB) copied, 0.000188717 s, 5.4 MB/s

Checking that no-one is using this disk right now ...

This disk is currently in use - repartitioning is probably a bad idea.

Umount all file systems, and swapoff all swap partitions on this disk.

Use the --no-reread flag to suppress this check.

Re-reading the partition table ...

The command to re-read the partition table failed.

Run partprobe(8), kpartx(8) or reboot your system now,

before using mkfs

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).)
