Hello, i just got myself a bare STM32F103VET6 and designed myself a PCB to just make all the pins easy to access on a Breadboard.
Now i just want to connect to the chip via the STLINK V2 (clone) and the STLINK Utility Software.
But every time i get an error that the STLINK Utility is not able to connect to the Chip.
14:04:17 : Can not connect to target!
Please select "Connect Under Reset" mode from Target->Settings menu and try again.
If you're trying to connect to a low frequency application , please select a lower SWD Frequency mode from Target->Settings menu.
14:04:20 : Internal command error
This is how i have connected the device:
STLINK V2 STM32
3.3V <---> VCC
GND <---> VSS
SWDIO <---> PIN72 (SWDIO)
SWCLK <---> PIN76 (SWCLK)
I tried pulling BOOT0 High and low, and kept it floating, none worked.
I used an Oscilloscope to check if there is signal getting to the pin (checked for broken cable). There is something happening, but the Oscilloscope i have right now is not good enough to see the actual Signal, just that there is a signal.
I tried resetting the chip with pulling the RST Pin low, and erasing the Memory via the STLINK Utility, same error.
I have a small capacitor between VSS and VCC.
I already tried a 2nd STM32 because i thought i might have damaged the chip while soldering. Still same problem.
I am really lost at this point and dont know where to look or what to try.
So i would be really thankfull for any kind of help or input.
