A question in relation to OB behavior discussed this thread: https://community.st.com/t5/stm32-mcus-embedded-software/stm32-is-getting-stuck-frozen-and-enables-read-out-protection-at/td-p/615228
Is there documentation or App note that explains what happens (by design or otherwise) when STM32 detect corruption of OBs during load? Especially, considering possible radiation damage, torture attacks etc. causing denial of service?
So let's see... BOR=0 assume OK... WRP none - assume OK. RDP level 1 - assume OK, can be recovered via debug interface... But RCROP on whole flash? this will cause immediate failure of firmware not built in the PCROP mode (execute-only). Results in denial of service.
