Expected value for Option Byte "RDP": 0xBB, found: 0xAA

I am working on LoRa-E5 mini. When I try to erase the chip, I receive the error Error: Mass erase operation failed. Please verify flash protection. So I am trying to set RDP on level 0 to 1, but I am getting an Error: Expected value for Option Byte “RDP”: 0xBB, found: 0xAA Error: Option Byte Programming failed or modified by application after OB_LAUNCH.

Any help would be greatly appreciated.

Hi, I am facing the same problem with my LoRa wio e5. Did you solve it? If so how?

I didn’t find the any exact solution. But if you have to change the Option byte from 0xAA to 0xBB and then try it might work. Let me know if it worked.
