Example Design: SPI Passive Programming with Raspberry Pi

One of the methods to configure a Trion® FPGA is using the SPI passive configuration mode. In SPI passive mode, an external microprocessor or microcontroller sends the bitstream to the Trion® FPGA using the SPI interface. A Raspberry Pi computer can act as a microcontroller in the passive mode configuration mode. Efinix provides example designs that demonstrate a Raspberry Pi computer configuring the Trion® T20 MIPI Development Board using passive SPI mode. This example design includes C and Python Raspberry Pi software examples. The software examples provided support up to x32 SPI passive mode.
