Function Documentation

uint8_t BSP_QSPI_DeInit ( void   )

De-Initializes the QSPI interface.

Return values:
QSPImemory status

Definition at line 165 of file stm32746g_discovery_qspi.c.

uint8_t BSP_QSPI_EnableMemoryMappedMode ( void   )

Configure the QSPI in memory-mapped mode.

Return values:
QSPImemory status

Definition at line 506 of file stm32746g_discovery_qspi.c.

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:
QSPImemory status

Definition at line 308 of file stm32746g_discovery_qspi.c.

uint8_t BSP_QSPI_Erase_Chip ( void   )

Erases the entire QSPI memory.

Return values:
QSPImemory status

Definition at line 397 of file stm32746g_discovery_qspi.c.

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:
QSPImemory 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).

Definition at line 356 of file stm32746g_discovery_qspi.c.

uint8_t BSP_QSPI_GetInfo ( QSPI_Info *  pInfo )
