Hello to everyone. I am using Stm32f0 discovery (ST-Link) for the programmer. I will load the to external processor (STM32L011D3P6). I edited the Flash settings in Keil IDE. I get this error:
'' Debugger - Cortex M Error , No target connected ''
'' Flash Download fail ,Target DLL has been cancelled ''
Is the problem can be sourced from flash settings?
Can you help me please ? Thank you.

Hello
Varl_k.Ufuk
‌,please check your wirings and make sure external MCU has power.
Verify that jumpers for ST-Link are removed on your discovery board.
Best regards,
Tilen

I've check it and problem is solved.Due to the connection error, the target processor feed was 1.5V. Now I can feed 3V. Thank you Tilen

Minimally SWDIO, SWCLK, and GND, would strongly recommend NRST also.
Reading the manuals and reviewing the schematics is also strongly recommended, host of information in them.
Up vote any posts that you find helpful, it shows what's working..

You must make JP2 connector is short current, CN2 socket is open current. Also, CN3 pins must be connected to processor.
