I use ST Visual Programmer and

. During programming I set Read Protection ON. But now I can not erase or reprogramming the chip (STM32F103RB). I can see ''The device is protected'' only. How can I do this?

you have to disable the read out protection before

I did not yet mess with Visulal Programmer, but a ''Full Erase'' should be possible anyway.

The CRP feature is described in detail in the stm32f10x reference manual. I would avoid it if possible...

Yes, I have to disable the read out protection before. But I should be able to erase the chip in the future. And I can't do it via ST Visual Programmer. What are opinions?

Serial port, or JTAG

I've also done it with code I built into one of my applications.
