Example spi_hw does not work

[71GA]

Example spi_hw does not work. When I run C program to send SPI commands to the slave (FPGA), later returns a bunch of 0xFF:

┌───┐
│ $ │ ziga > ziga--workstation > spi_host
└─┬─┘ /dev/pts/2
  └─> ./host
init..
bit inversion read idx 0: 0xff, should be 0xc7
bit inversion read idx 1: 0xff, should be 0x51
bit inversion read idx 2: 0xff, should be 0xc4
bit inversion read idx 3: 0xff, should be 0xb7
LED command answer from fpga: the first byte should be the command (0x4), the second byte should by the LED colour

Hello,

It will be a bit hard to find what the problem is without more info, but here are a couple of questions/suggestions:
Were you able to synthesize and test with success other examples of the project, something with more direct feedback such as the LEDs?
Were you able to run the soft-SPI (not hardware module) example?
Are the jumpers correctly set on your board (if you are using the breakout board, which those examples are aimed for), in order to communicate with the ice40 directly and not the flash (see https://www.latticesemi.com/view_document?document_id=51987) ?
