RESOLVED!

Using ST-Link Utility it is not possible program non generic/non STM board. I used Keil, it's working properly.

Thanks

Hello All,

I found lot of postes with the same question: How to disable Read Out Protection. But, unfortunately, no sucessfull solution of that. 

I'm using ST-Link V2, target SAMD21 Adafruit Feather M0 board. Not able to disable Protection, not able to erase chip, still only one answer/exception: Cant disable RDP, or RDP is active, can't erase mem, etc etc.

Could you please someone advice me to solve this issue? It it possible to erase chip on non generic board like Adafruit Feather?

Thanks in advance for your help!

Don't expect support for Atmel / Microchip parts.

To be honest, I thought, that ST-Link V2 is ST product, tool, used for programming/debugging of wide scale of development boards. Your reply is strange, anyway, I resolved this issue using Keil Software together with ST-Link. Keil allows using as debug interface ST products, I'm sure, that it is normal. For instance BOSCH drill can be used for drilling of holes in non BOSCH materials.

Anyway, thanks for your reply.

You're wrong, it's generic board, fully compatible with STm32, using Keil uVision + ST-Link I erased memory, also registers, and then it's working properly using ST-Util.

Your issue is more one of trying to use Ford engine parts in a Fiat, or using a Ford engine diagnostic application. The ST-LINK Utilities only understands ST parts, while the SWD/JTAG comms are the same, the behaviour of the flash memory and peripherals will be different.
