为什么LATTICE官方的crosslink开发板在擦除了一下片外FLASH后就再也烧不进去程序了？

我买了一块LATTICE官方名字叫作CrossLinkLIFMD6000MasterLinkBoard的DEMO板，在我整片擦除了片外的FLASH后想重新再烧录时，却始终报如下错误：

INFO - Check configuration setup: Successful (Ignored JTAG Connection Checking).

INFO - Device1 LIF-MD6000: SPI-M25PX16: SPI Flash Erase,Program,Verify

我用烧录器按上述连线，再接上VCCIO0 及GND后，点Detect Cable后， No Board with FTDI USB Host Chip detected. Lattice HW-USBN-2A cable detected. No Lattice HW-DLN-3C (parallel) cable detected. Detected HW-USBN-2A cable at port EzUSB-0. 再点programmer后报错，烧录失败，为什么？
