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

‌ - Great. Your post helped me. I am also looking to program my STM32F030R8 with STM32F0 Discovery board. What are the connections required on my target mcu ?

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.

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