I have a question regarding the W7500P IAP functionality. In the IAP example for the W7500 there is some functionality for erasing, reading and writing the flash, but I can’t find anything to protect the flash from reading and writing.
The reference manual chapter 9.3.1 states one can read protect the flash by writing the CRL bit in the FLOCKR0 register. But I can’t find which bit the CRL bit is?
I know the FLOCKR0 register is located at address 0x4100 5014, but my question is: which bit in this register is the CRL bit? And is this bit responsible for the read protection, or is there another way to read/write protect the chip?
Can u advise me how to set read-protection in normal boot mode?
Above link is for boot mode.
I’d like to know how to enable flash read protection in my already alread deployed firmware.
일반부팅상태일때 펌웨에서 read-protection을 설정하는 방법이 있을까요?
저는 기존에 배포된 펌웨어에서 새로운 버젼으로 펌웨어 업데이트하면 새로운 펌웨어가 실행될때 read-protection기능을 부여하거나 다음 업데이트 부터는 flash read-protection(lock flash reading)을 설정하고 싶습니다.
