To make a NAND erase, you need to connect to your device while in uboot using minicom or cu. The device will usually be called /dev/ttyACM0. You might need to
sudo chown uucp.uucp /dev/ttyACM0
to get the necessary right (even as root). Using cu, you can then access the Neo:
cu -l /dev/ttyACM0
After connecting, you should get a prompt where you can tell u-boot to clean certain parts of the NAND memory.
