I am trying use the stm32wb15cc to run an application on CPU1, but with no application in CPU. I don't need the RF side at all and want to hold CPU2 in reset and allow CPU1 to access all the Flash and Ram.
However this does not seem possible as Option Bytes are set to reserve parts of the flash and RAM 2a and 2b, so I have limited access. Apparently these bits can only be reset by CPU2. I tried using the Cube Programmer, but it was not able to change these bytes.
Is it possible to clear these bytes in some manner? Or can ST provide a binary for CPU2 that removes the security or just reduces the RAM lock to just the last 1KB of each region?
