Function Documentation

status_t Nor_Flash_Init	(	nor_config_t *	config,
		nor_handle_t *	handle
	)

This function initialize NOR Flash controller and NOR Flash.

Parameters

config

NOR flash configuration. The "memControlConfig" and "driverBaseAddr" are controller specific structure. please set those two parameter with your Nand controller configuration structure type pointer. such as for SEMC:

spifi_mem_nor_config_t spifiNorconfig = { ..... } nor_config_t config = { .memControlConfig = (void *) .driverBaseAddr = (void *)SPIFI0; }

Parameters

handle

The NOR Flash handler.
