Hi, do we have example code for how to do flash write / erase protection. Customer want to ensure their MP product will not lost or modify flash content. Even if code run fly and jump into flash erase API, still ensure the flash do not be erased.

Hi Marie

Thanks your advice, I have look TRM chapter 7.5.1 before and know cc2640r2f has flash protection feature. I still cannot understand clearly how to operate in detail to enable protection feature, the TRM seem not describe the operation method step by step, so I ask if we have example code or detail description paper to help customer implement protection features.

Hi Terry,

Did you also look at the CCFG section of the TRM? (9.1 Customer Configuration (CCFG))
