I am using the PN7642 processor and need to protect the user firmware image.
Based on the API, I am using "PN76_Sys_OTPConfigs_EnableCRP()" which is returning 0x07 "PN76_STATUS_AUTH_ERROR" which is NOT one of the expected returns documented in the API.
Can you please provide a detailed example of the process of activating Code Read Protection on this processor? There is little to no information beyond the actual function call documented in the API.
