For the TMS570LS3137 device Boot Loader Example available at the location http://processors.wiki.ti.com/index.php/TMS570_Hercules_MCU_Bootloader following Sectors Marked in Green I am able to Erase and Reprogram but the address starting from 0x00200000 to 0x002E0000 It is unable to Erase Or write to these Sectors .

For BANK 0 Sectors the F021 API Functions are used in following sequence
Fapi_initializeFlashBanks(Freq_In_MHz);
Fapi_setActiveFlashBank((Fapi_FlashBankType)bk);
Fapi_enableMainBankSectors(0xFFFE);
Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector, eraseStartAddr);
For BANK 1 Sectors the F021 API Functions are used in following sequence
Fapi_initializeFlashBanks(Freq_In_MHz);
Fapi_setActiveFlashBank((Fapi_FlashBankType)bk);
Fapi_enableMainBankSectors(0xFFFE);
Fapi_enableEepromBankSectors(0xFFFFFFFFU, 0xFFFFFFFFU); /* this fixed 0x00180000 to 0x001E0000 Sectors Erase and Write */
Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector, eraseStartAddr);
The Flash Setup function is as follows
