Lattice development boards (e.g. UP5K, ICE40HX8K, MachXO3LF) have an FTDI device configured with an SPI interface (for programming the device in SPI slave mode) and a UART interface, whereas the icepool board has uses two SPI interfaces.
For the sake of using the development boards, is it possible to substitute the second SPI interface, e.g.
