### ice40 boards (icestick, iCE40-HX8K, iCEBreaker, iCE40HX1K-EVB)
*.bin* is the default format generated by *nextpnr*, so nothing special
must be done.
Since most ice40 boards uses the same pinout between *FTDI* and *SPI flash* a generic *ice40_generic* board is provided.
For the specific case of the *iCE40HX1K-EVB* where no onboard programmer is present, please use this:
| FTDI | iCE40HX1K-EVB (PGM1) |
|--------------|----------------------|
| SCK (ADBUS0) | Pin 9 |
| SI (ADBUS1) | Pin 7 |
| SO (ADBUS2) | Pin 8 |
| CS (ABDUS4) | Pin 10 |
| RST (ADBUS6 | Pin 6 |
| DONE (ADBUS7)| Pin 5 |
__bin file load__
```bash
openFPGALoader -b ice40_generic /somewhere/*.bin
```
Since it's a direct access to the flash (SPI) the *-b* option is required.
