The warning messages says it can't read memory because RDP is enabled. Disabling RDP can be done within the option bytes (Target -> Option Bytes). Set it to level 0 and restart.

Hello @TVARS.1 ,

Welcome to the STM32 Community :smiling_face_with_smiling_eyes:.

I checked from my side and I have no problem, it works for me.

It's strange that you have the Flash size: Unknown !

As you see in the below screenshot, the flash size is 1MBytes.

So, please check that you have the correct dev ID, rev ID, flash size from the reference manual.
