Function Documentation

memc_nxp_semc_configure_nand()

int memc_nxp_semc_configure_nand	(	const struct device *	dev,
		semc_nand_config_t *	config,
		uint32_t	clk_src_hz )

Configure a NAND target on SEMC.

memc_nxp_semc_configure_nor()

int memc_nxp_semc_configure_nor	(	const struct device *	dev,
		semc_nor_config_t *	config,
		uint32_t	clk_src_hz )

Configure a NOR target on SEMC.

memc_nxp_semc_configure_sdram()

int memc_nxp_semc_configure_sdram	(	const struct device *	dev,
		semc_sdram_cs_t	cs,
		semc_sdram_config_t *	config,
		uint32_t	clk_src_hz )

Configure an SDRAM target on SEMC.

memc_nxp_semc_configure_sram()

int memc_nxp_semc_configure_sram	(	const struct device *	dev,
		semc_sram_cs_t	cs,
		semc_sram_config_t *	config,
		uint32_t	clk_src_hz )

Configure an SRAM target on SEMC.

memc_nxp_semc_get_default_config()

int memc_nxp_semc_get_default_config

(

semc_config_t *

config

)

Populate a SEMC configuration with MCUX defaults.

Parameters

config

Pointer to destination configuration.

Return values

0	on success.
-EINVAL	if config is NULL.

memc_nxp_semc_reconfigure()

int memc_nxp_semc_reconfigure	(	const struct device *	dev,
		const semc_config_t *	config )

Reconfigure the SEMC core block.

This updates common SEMC options (timeouts, queue weight, DQS mode). It software-resets the controller and leaves it without any configured external device; memory interface timing and base address are programmed separately with memc_nxp_semc_configure_*().

Parameters

dev	SEMC controller device.
config	Common SEMC configuration.

Return values

0	on success.
-EINVAL	if arguments are invalid.
-ENODEV	if device is not ready.

memc_nxp_semc_soft_reset()

int memc_nxp_semc_soft_reset

(

const struct device *

dev

)

Trigger SEMC software reset.

Parameters

dev	SEMC controller device.

Return values

0	on success.
-EINVAL	if arguments are invalid.
-ENODEV	if device is not ready.
-ETIMEDOUT	if reset did not complete in time.
