Function Documentation

uint8_t BSP_QSPI_DeInit

(

void

)

De-Initializes the QSPI interface.

Return values:

QSPI	memory status

Definition at line 165 of file stm32l476g_discovery_qspi.c.

References QSPI_ERROR, QSPI_MspDeInit(), QSPI_OK, and QSPIHandle.

uint8_t BSP_QSPI_EnableMemoryMappedMode

(

void

)

Configure the QSPI in memory-mapped mode.

Return values:

QSPI	memory status

Definition at line 506 of file stm32l476g_discovery_qspi.c.

References QSPI_ERROR, QSPI_OK, and QSPIHandle.

uint8_t BSP_QSPI_Erase_Block

(

uint32_t

BlockAddress

)

Erases the specified block of the QSPI memory.

Parameters:

BlockAddress,:

Block address to erase

Return values:

QSPI	memory status

Definition at line 308 of file stm32l476g_discovery_qspi.c.

References QSPI_AutoPollingMemReady(), QSPI_ERROR, QSPI_OK, QSPI_WriteEnable(), and QSPIHandle.

uint8_t BSP_QSPI_Erase_Chip

(

void

)

Erases the entire QSPI memory.

Return values:

QSPI	memory status

Definition at line 397 of file stm32l476g_discovery_qspi.c.

References QSPI_AutoPollingMemReady(), QSPI_ERROR, QSPI_OK, QSPI_WriteEnable(), and QSPIHandle.

uint8_t BSP_QSPI_Erase_Sector

(

uint32_t

Sector

)

Erases the specified sector of the QSPI memory.

Parameters:

Sector,:

Sector address to erase (0 to 255)

Return values:

QSPI	memory status

Note:

This function is non blocking meaning that sector erase operation is started but not completed when the function returns. Application has to call BSP_QSPI_GetStatus() to know when the device is available again (i.e. erase operation completed).
