Hello guys. I was trying to read the code out of a STM32F105RBT6 using a SWD circuit and the STMprog software but the code was ''Read protected'' and I couldn't bring it out .
Can you guys give me a help or suggestion on this? Is that possible at all? Or is there probably a professional programmer out there capable of unlocking the ARM chips?Cheers. #stm32-read-protection2012-02-18 03:43 PM
The methods provided by ST to remove the read-out protection also mass erase the part.
The serial port system loader can be used to do this, and probably the ST-LINK tools.2012-02-20 02:09 PM

since Clive is your brother, I hate to interfere in a family affair. However what is difficult? all tools known too me has an 'erase chip' command. Erik2012-02-27 12:20 PM

since Clive evidently is your brother, I hate to interfere in a family affair. However what is difficult? all tools known too me has an 'erase chip' command. If there was a (relatively) simple way to bypass the read protect, why would the manufacturer bother implementing read protection. The only reasons I can see for 'breaking' a read protect are dishonest. Erik2012-02-27 12:58 PM
