Function Documentation

vsf_sdio_probe_start()

vsf_err_t vsf_sdio_probe_start	(	vsf_sdio_t *	sdio,
		vsf_sdio_probe_t *	probe
	)

start sdio probe, SDIO MUST be initialized by calling vsf_sdio_init first.

Parameters

[in]	sdio_ptr	a pointer to structure vsf_sdio_t
[in]	vsf_sdio_probe_t	a pointer to struct vsf_sdio_probe_t

Returns

vsf_err_t: on success, returns VSF_ERR_NONE(0); on error, returns err code(< 0)

vsf_sdio_probe_irqhandler()

vsf_err_t vsf_sdio_probe_irqhandler	(	vsf_sdio_t *	sdio,
		vsf_sdio_probe_t *	probe,
		vsf_sdio_irq_mask_t	irq_mask,
		vsf_sdio_reqsts_t	status,
		uint32_t	resp[4]
	)

called in sdio irqhandler while probing sdio.

Note

if probe->delay_ms is none zero after returned with VSF_ERR_NOT_READY, vsf_sdio_probe_irqhandler(irq_mask: 0, status: 0) should be called again after delay_ms delayed.

Parameters

[in]	sdio_ptr	a pointer to structure vsf_sdio_t
[in]	vsf_sdio_probe_t	a pointer to struct vsf_sdio_probe_t
[in]	irq_mask	one or more value of enum vsf_sdio_irq_mask_t
[in]	status	transact status.
[in]	resp	response.

Returns

vsf_err_t: on success, returns VSF_ERR_NONE(0); on going, returns VSF_ERR_NOT_READY(> 0); on error, returns err code(< 0)
