Since David has tried it already I'd wait for his input, but I think this is the mapping:
J1.1 = 3.3v J1.2 = gnd J1.3 = gnd (only one flash chip to select) J1.4 = tck J1.5 = tdo J1.6 = TDI J1.7 = no connect J1.8 = 3.3v The spi flash will get powered by the programmer so don't power the MinnowBoard.
