Serial Peripheral Interface (SPI) is a synchronous, serial hardware bus communication protocol used for intra-board (short distance) communication i.e. between two components on a circuit board. It is a 4-wire bus. The communication is full-duplex as it has separate lines for master-to-slave and slave-to-master communication. In many devices, you may encounter flash memory chips, for example, that talk over SPI for data read/write and you may need a way to extract data from the chip for further analysis or write malicious data to the chip.
The current implementation is dependent on pyspiflash package which in turn is dependent on pyftdi package. Note that there will be some extra info printed on the console, when the plugin executes, which comes from the pyspiflash package and is not part of the plugin code. To interface your PC with the SPI flash chip, you need a hardware connector or bridge. You can use any FTDI based device, that provides an SPI interface. We have created a multi-protocol connector called EXPLIoT Nano which is available at our online store. Although, the framework should work with any pyftdi compatible FTDI device.
