The programmer is easily controlled by your host computer using the DediProg Software through the USB bus. The SF100 is a high speed “In System Programming” programmer to update the SPI Flash soldered on board the MinnowBoard development board. You will use your separate development system to connect to the DediProg SF100 tool to program the flash chip on the board.ĭediprog SF100 SPI Flash programming tool The MinnowBoard development board is unpowered for this tutorial. The standard MinnowBoard development board firmware is demonstrated in this tutorial however, the method illustrated in this tutorial can also be used to load any of the alternative boot loader firmware options available for the MinnowBoard development boards. DediProg Windows Application v6.05.18 and USB Driver v5.5.03.Download the appropriate one for your host system below: Software components DediProg SF100 Application softwareĭediProg provides application software for Windows and Linux. If you don’t have a board yet, compare all the available boards and view links on where to buy them in your geographic region. When that is the case, the tutorial calls out this component, reflecting that any one of the board variants will work. Some tutorials are board agnostic-they will work on any family or version of a MinnowBoard development board. Essentials Hardware components MinnowBoard Development BoardĪ single board computer (SBC) that offers performance, flexibility, openness, and support of standards. This tutorial is based on Windows 8.1 and has also been tested on Windows 10. The standard MinnowBoard development board firmware is demonstrated however, the method illustrated in this tutorial can also be used to load any of the alternative boot loader firmware options available for the MinnowBoard development boards. You can use the tool to flash firmware on multiple boards in quick succession, and this method is especially handy for this serial bulk programming use. It directly accesses the boot flash chip and the board remains unpowered. The tutorial will update the firmware on a MinnowBoard development board using a DediProg SF100, an SPI Flash programming tool. Flashrom autodetects the presence of libftdi headers and enables FT2232/FT4232H/FT232H support if they are available.

Recent versions of flashrom support the -p ft2232spi (or -p ft2232spi in older flashrom revisions) option which allows you to use an FTDI FT2232/FT4232H/FT232H based device as external SPI programmer. This address ranges from 0 to SPI flash size and is not the processor’s absolute range. The data is read from the memory location specified by the first parameter.

Accessing Serial Flash Memory Using SPI Interface 4 spiflashread This function reads the content from the serial flash.
