I have demoboard with STM32F417 and ST-Link v2. After some software fault, read out protection was activated. STlink utility print 
20:07:57 : Connected via SWD.
20:07:57 : Device ID:0x411 
20:07:57 : Device family :STM32F4xx
20:07:57 : Cannot read memory!
                  Disable Read Out Protection and retry.

What I mast to do to disable read out protection. I can't to do full erase of chip with the same error:
STM32 ST-LINK CLI v1.3.0
STM32 ST-LINK Command Line Interface

Connected via SWD.
