Recent versions of flashrom support the -p ft2232spi option which allows you to use a FTDI FT2232H/FT4232H based device as external SPI programmer.

This is made possible by using libftdi. flashrom autodetects the presence of libftdi headers and enables FT2232H/FT4232H support if they are available.



DLP Design DLP-USB1232H


  • Put a jumper on pins 8 and 9, which configures the device to be powered by USB. Without this jumper it will not be powered, and thus not be detected by your OS (e.g. it will not appear in the lsusb output).
  • Connect a 3.3V voltage regulator and two capacitors (e.g. 100nF and 10uF) so you can power the 3.3V SPI BIOS chip.
    • TODO: Details
  • Connect the following pins from the DLP-USB1232H to the SPI BIOS chip:
    • 18 (SK) to SCLK
    • 16 (DO) to SO# (?)
    • 2 (DI) to SI# (?)
    • 5 (CS) to CS#
    • The WP# and HOLD# pins are left unconnected (?).
  • TODO
