Minnowboard:SPI Boot flash

the MinnowBoard uses a SPI based serial flash memory to load the initial code into the Intel Atom E640 series processor. The MinnowBoard uses a WinBond W25Q32 ([[media:winbond-w25q32.pdf|datasheet]]) which has a total of 4096KB of storage which can be flashed with a UEFI image or other custom firmware.

= Programming Interface =

the MinnowBoard has a 2x4 header that has 0.1" spacing for programming the SPI based serial flash memory.
