Function Documentation

nvram_spi_init()

int nvram_spi_init	(	nvram_t *	dev,
		nvram_spi_params_t *	spi_params,
		size_t	size
	)

Initialize an nvram_t structure with SPI settings.

This will also initialize the CS pin as a GPIO output, without pull resistors.

Parameters

[out]	dev	Pointer to NVRAM device descriptor
[out]	spi_params	Pointer to SPI settings
[in]	size	Device capacity

Returns

0 on success

<0 on errors
