Flashing MinnowBoard Max with Dediprog SF-100 in Linux This tutorial explains how to flash your MinnowBoard Max with a Dediprog SF-100 SPI programmer using a host computer running an Ubuntu Linux operating system. The MinnowBoard Max can be flashed with other programmer tools in other Linux environments, but this tutorial focuses on the SF100 and Ubuntu. In this tutorial, Flashrom is the application used to program the MinnowBoard Max in Linux. 1. Disconnect the power supply from the MinnowBoard Max. The DediProg (SF-100) is unable to flash while the MinnowBoard Max power supply is connected. CAUTION: CAUTION: There is the possibility of damaging the SF-100 if it and the MinnowBoard Max power supply are connected simultaneously. August 13, 2014 Revision 1.0 1 2. Locate the grouping of headers just beside the SATA connector and the Power Switch, on the top of the MinnowBoard Max (the side with the processor). The 2x4 grouping of pins labeled (J1) is where the SF-100 will connect. 3. Connect the DediProg cable to the 2x4 PROG header so that the red wire of the cable is on the pin 1 side of the header that is furthest from the power switch. Pin 1 is next to the SATA connector Pin 1 August 13, 2014 Revision 1.0 2 4. Download the latest version of Flashrom from http://flashrom.org/Downloads 5. From the downloaded archive, unpack the flashrom directory to the location of your preference, then open a terminal and navigate into that directory. Note: You will probably need to install the pciutils-dev and libusb-dev packages to build flashrom. You can install them with apt-get:$ sudo apt-get install pciutils-dev libusb-dev 6. Enter the command: sudo CONFIG_DEDIPROG=yes make 7. After the make process has finished building flashrom, install flashrom as an executable command. Do this by using root user permissions and typing sudo make install. 8. Type flashrom to get a list of programmers that includes the option dediprog. 9. Navigate to the location of the MinnowBoard Max firmware image that you would like to install. 10. With root user permissions execute the command sudo flashrom –p dediprog –w <firmware image name here>. August 13, 2014 Revision 1.0 3 11. Wait until the flashing process has completed and the flash part is VERIFIED. 12. Disconnect the programmer. 13. Reconnect the power supply to boot the MinnowBoard Max. Two Blue LED lights will turn on indicating that the MinnowBoard Max is powered on and in its boot-up sequence. August 13, 2014 Revision 1.0 4
