LP-EM-CC2340R5: Question about programming the CCFG.

Weiting Liao

Part Number: LP-EM-CC2340R5

Tool/software:

Hello TI Support Team,

I have developed a bootloader and am attempting to update my application and CCFG. However, when erasing the flash address 0x4E020000 (CCFG) using the FlashEraseSector function, it returned FAPI_STATUS_FSM_ERROR.

Could you please guide me on how to resolve this issue?

Thank you for your assistance.

    Hello,

    CCFG can only be erased as part of a chip-erase (e.g. BLDR_CMD_CHIP_ERASE if using SBL, and SACI_CMD_FLASH_ ERASE_CHIP if using SACI).

    This is by design to prevent security vulnerability.

    Thanks,
    Toby
