Which serial port are you using for erasing the NAND flash?
You need to mention serial port info for "-p" argument.
Could you please attach your error logs which you received from sfh?
ex,
If it is COM1,
sfh_OMAP-L138.exe -targetType OMAPL138_LCDK -flashType NAND -p COM1 -erase (in windows)
sfh_OMAP-L138.exe -targetType OMAPL138_LCDK -flashType NAND -p /dev/ttyUSB0 -erase (in Linux)
