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 (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.

Applications and Hardware

  • Flashrom is an open source utility that allows you to work with the SPI based serial flash memory on the MinnowBoard.
  • Flashrom supports a wide range of flash devices (Supported Hardware) including the WinBond W25Q32.
  • Flashrom can automatically detect the presence of the WinBond W25Q32 and provide full read/erase/write functionality.
  • Flashrom can use the many open as well as proprietary hardware tools such as
