How to Program and Debug micro STM3203

[vdavi81]

Hi,

I developed a boiard with micro STM32F030C8T6TR. But when I try to create a software in STMcubeMx Build and Debug. I can always  build succesfully my project, but When I try to Flash and Debug STcubemxIDE  open a popup with wrote, as following reported: 

Target connection failed

Target no device found

Error in initializing ST-LINK device.
Reason: No device found on target.

I'm usinf STM32 LINK v2 Debugger, with SWD I respected pinout connection. Following, microprocessor section, taken on the schematics:

And the Debug connector schematics

SomeBody Can help me to understand Why I cannot Flash and Debug, receving error messsage.

Your schematics is buggy need connet VSSA and VDDA

[vdavi81]

But I don't need to use Analog, then VSSA and VDDA are not mandatory.

MCU isnt analog as you mean, for example ADC part power on reset or clock oscilator is powered from "analog" as you connect now your MCU is dead

[vdavi81]

Ok I tried to connect both of VDDA and VSSA, Can I connet them to VDD e GND? SWD Debug Peripheral need VSSA and VDDA?

Another question NRST need pull-up Resistor?

Open Nucleo 030 schematics and learn.

Ok .. Now I tied to connect everythig after that I let you know if I need still help.
