Using Rlink with Rflahser, it is OK to mark the read-out protection in option byte action!
but I can not unprotect it, I tried to earse the chip, or unmark the read-out protection in option byte action and restore default option bytes,but when I connect to target, it still shows the device is protected! or read out data are all 00!

Try to reprogram the option byte in RAM boot mode (with the current release). It should erase the protection.
