I am facing a problem with the MCU model STM32F105RB. I am using it with the J-link EDU.

I use a custom hardware, which works properly with the STM32F205RB model. Now I am trying to use the same custom hardware with the model STM32F105RB, adding the two resistors as stated in the datasheet (see next figure).

The problem is that when communicating with the MCU via the J-Link Commander, I am getting this error:

I have also read in the segger forum that to unlock the MCU it is also necessary to use first the J-Link STM32 Unlock, but it trhows the following error.
