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.

Direct dependencies¶

SPI_SIFIVE && SPI

(Includes any dependencies from if’s and menus.)

Defaults¶

“y” if SPI_SIFIVE && SPI

Kconfig definition¶

At drivers/spi/Kconfig.sifive:17

Included via Kconfig:10 → Kconfig.zephyr:35 → drivers/Kconfig:36 → drivers/spi/Kconfig:203

Menu path: (top menu) → Device Drivers → SPI hardware bus support → SiFive SPI controller driver
