3.5.6 Fapi_issueProgBankMode()

Erases and then programs the BANKMGMT sector of the specified FLC.

Synopsis

Fapi_StatusType Fapi_issueProgBankMode(
                        Fapi_BankMgmtAddress    u32StartAddress,
                        Fapi_BankMode  u32BankMode, 
                        Fapi_FlashStatusWordType   *poFlashStatusWord,
                        uint32_t    u32UserFlashConfig
);

Parameters

Fapi_BankMgmtAddress [in] The FLC to issue the programming command to.
Fapi_BankMode [in] Bank Mode to program the device to
Fapi_FlashStatusWordType [in/out] Returns the status of the operation if result is not Fapi_Status_Success
->au32StatusWord[0] Address of first non-blank location
->au32StatusWord[1] Data read at first non-blank location
->au32StatusWord[2] Value of compare data (always 0xFFFFFFFF)
->au32StatusWord[3] N/A
u32UserFlashConfig [in] User flash configuration bitfield

Description

This function erases and programs the inactive BANKMGMT sector with the given Bank Mode at the corresponding FLC. After programming the BANKMGMT sector, an external reset (XSRn) can be issued in order for boot ROM to read the new value and write it to the SSU register, completing the bank mode switch.

Return Value

  • Fapi_Status_Success (success)
  • Fapi_Status_FsmBusy (FSM busy)
  • Fapi_Error_FlashRegsNotWritable (failure: Flash register writes failed. The user can make sure that the API is executing from the correct CPU).
  • Fapi_Error_FeatureNotAvailable (failure: User passed a mode that is not supported)
