Hi,
I'm trying to program one custom board with STM32G0B1RET using original STLINK V3 and STLINK V2 without succes.
My schematic is very simple as you can see on the image:
And the response all time is: Not STM32 target found.. if I use SWD port.
If I use JTAG the response is: ST-LINK error (DEV_UNKNOWN_MCU_TARGET)
I've revised all the connections, voltages (both on the board and STLINK-V2), capacitors, lowered freq.,etc without success.
Also I've tried with Hot plug, Hardware Reset, Power down, Under reset, etc.
The log is like this:
22:03:41 : ST-LINK SN : 0672FF485570854967095517
22:03:41 : ST-LINK FW : V2J46M32
22:03:41 : Board : NUCLEO-G0B1RE
22:03:41 : Voltage : 0.02V
22:03:41 : Error: Unable to get core ID
22:03:41 : Error: ST-LINK error (DEV_UNKNOWN_MCU_TARGET)
What can be the problem?
I've 25 years designing electronics and is not my first board with STM32 devices (the previous one works perfectly) but I've finish all my arsenal of knowledge!
Thanks.
