Function Documentation

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

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

Parameters
[out]devPointer to NVRAM device descriptor
[out]spi_paramsPointer to SPI settings
[in]sizeDevice capacity
Returns
0 on success
<0 on errors
