WebThe Serial Peripheral Interface ( SPI) bus is a four wire master/slave full duplex synchronous bus. You can hook up multiple slave devices by utilizing chip select lines. The bus is composed of two data pins, one clock pin, and one chip select pin: SCLK - Serial Peripheral Interface Clock Signal (generated by the master) (also referred to as SCK) WebOn ROCK Pi 4 V1.3 and earlier, the design has included the SPI flash but it was not soldered. There are several reasons: The SPI is also exported on the 40PIN GPIO header, if we use it as boot rom, then we will not able to use the SPI bus on the GPIO header. If the bootloader in the SPI flash corrupted, it will brick the ROCK Pi 4, which is ...

WebDec 22, 2024 · Spiffs uses the nor flash way of writing extensively, where a written byte is sort of AND-written. E.g. say you have a byte on your flash being erased, i.e. is 0xFF. If you first write 0xFE and then 0x7F to this same byte, spiffs expects this byte to be read as 0x7E.
