Hello Everyone,

My name is Shehraz and im working at Rove Automation Dubai. I am new to this community, and i need help on my current project. We are using Schneider switches (SEGC12PB) and i need to upgrade firmware on the switches.

we are using STM32f0Discovery for upgrading switches and ST-Link Utility software . I set the Read out protection to LEVEL 3 and now im not able to connect to target switches. Please can you tell me how to reset it back to level 0.

reply me if you need further clarifications on this.

Thanks

What does the description of

Read out protection LEVEL 3 in the STM32 datasheet tell you?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
