STM32L053 Nucleo Board.

I am trying to program or erase board using ST-LINK_CLI.exe (Ver 1.3.0) / STM32-LINK Utility (Ver 2.3.0) but I get error message saying 'Read out protection is activated' 

I am not able to erase or program boards. Similarly, I am not able to program/debug example project using Atolloic Studio.

Can you please help to find a way tp erase / program boards by disabling 

Read out protection

Hi

,

To disable memory read protection go to : STM32 ST-LINK Utility >Target > Option Bytes:

please refer toRDP (Read Out Protection) section on your reference manual to have idea about this type of protection

I was using OLD version of ST utility which was not supported to erase option bytes and remove read protection. The new version of ST link utility (V4.0.0) helped me to remove read /write protection

I did not find STM32 ST-LINK Utility for Linux...
