Re: esp_wifi_init - what are the record types in the queue?

Re: How does Flash Encryption (aka Secure Boot) work?
Some parts of OTP, such as flash encryption key, are not readable from application. It is generated by hardware and stored in OTP. Flash decryption engine can load encryption key directly from OTP.
