CONFIG_SIFIVE_SPI_0_ROM
¶
SPI 0 is used to access SPI Flash ROM
Type: bool
Help¶
If enabled, SPI 0 is reserved for accessing the SPI flash ROM and a driver interface won’t be instantiated for SPI 0.
Beware disabling this option on HiFive 1! The SPI flash ROM is where the program is stored, and if this driver initializes the interface for peripheral control the FE310 will crash on boot.
