does sfh_DM35x.exe support MLC plash?

I used sfh_DM35x.exe to program the MT29F16G08FAA by using UART port in my
DM355 EVM. it succeeded! The board can boot up. However, When i use MLC
Flash: MT29F8G08MAD, the procedure of program did show anything wrong. But
board can't boot up. Someone know why it is?
