Very essential tool for iCE40 FPGAs SRAM bitstream programming using bare bones FTDI C232HM MPSSE cable. Does not support (yet) serial flash programming. Tested on Ubuntu 16.04.2, Cygwin and MinGW (with Windows Zadig driver) with UPDuino V1 and GoBoard FPGA boards.
Connect FTDI cable wires as follows:
| Signal | FTDI cable color | UPDuino |
|---|---|---|
| CLK | Orange | JP2-3 |
| MOSI | Yellow | JP2-1 |
| CS | White | JP2-5 |
| RESET | Blue | JP1-2 |
| Vdd | Red | JP2-2 |
| GND | Black | JP2-6 |
Leave J1 unpopulated. A blinky LED bitstream example is provided for testing purposes in the 'test-designs' directory
Go Board can only work with the bitbanged version of the tool as MISO and MOSI signals are configured for iCE40 master mode (i.e.: loads bitstream from external serial flash).
Install libftdi: apt install libftdi1-dev.
Copy (as root) the contents of udev-rules directory into /etc/udev/rules.d/ if willing to use MPSSE cable as non-root user.
Install libftdi1: on MinGW use 'Pacman' package manager. On Cygwin use its package installer.
Use Zadig to install WinUSB driver over first USB/Serial converter (Interface 0) as shown here:
Note: libmpsse essential sources are embedded in the project for convenience as there's no Debian package for it yet. TODO: Fix broken build of SPI tool version (bit banged one works fine).
