Hello,
I bought STLINKV2 + small board with STM32F103C8T6. I tried to create a simple program - LED blinking - according to example in here: https://deepbluembedded.com/stm32-gpio-write-pin-digital-output-lab/ and I have STMCubeIDE + MX + others.My STLINKV2 has newest firmware.
Compilation of my example algorithm (in IDE) is ok (see below) , programming is ok, but debugging shows me an error:
**************************************
Target is not responding, retrying...
Target is not responding, retrying...
Shutting down...
*************************************
Can someone help me where is problem ? I would like to try "JTAG/SWD debugging funtion" of my program - i.e. functions "stepOver", "stepInto" etc. Program on processor is running ok and LEDs are blinking ok.
