TMS570LC4357: EEPROM erase error！

Hi all：

    I follow the recommanded flash erasing flow to erase the eeprom(bank 7). However something wrong happened, when I finished erasing whole bank 7, then writing data to  it, the MCU will reboot forever.

    Here below is my erasing code, btw, I have init the flash bank upper:

   nRetVal = (U32) Fapi_setActiveFlashBank((Fapi_FlashBankType) (U32)Fapi_FlashBank7);
   nRetVal = (U32) Fapi_enableEepromBankSectors((U32) 0xFFFFFFFFu, (U32) Q_F021_EE_SECTORS_63_32_DISABLED);
   F021_flashWaitForReady(0); 
   nRetVal = (U32) Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector,0xF0200000u);
   F021_flashWaitForReady(0); /* wait if FSM is busy */
   Fapi_flushPipeline(); /* defensively to flush buffers after every content modification */

   I am not sure about the function "Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector,0xF0200000u)", the variable 0xf0200000.

  I want to erase the whole bank 7, so I think the start_addr is the start address  of bank7.

    Also, is there any write-protection for this bank 7 ?

我手边没有这个板子，所以请其他同事测试了一下。您可以看一下其回复
