I'm back, and working with the stm32g070rb chip. I did prototyping on a nucleo board based on the same chip (split the st link and nucleo board), and wired the ST Link to the microcontroller with the following connections
I used open-ocd for flashing code to the nucleo, and it worked flawlessly. Based on the wiring, I made the assumption that this'd translate directly when developing the PCB.
(picture of the PCB and the schematic)
When I tried to make the same connections, and tried to flash, I'd get the following issue
```bash
Info : auto-selecting first available session transport "hla_swd". To override use 'transport select <transport>'.
Info : The selected transport took over low-level target control. The results might differ compared to plain JTAG/SWD
Info : clock speed 2000 kHz
Info : STLINK V2J31M21 (API v2) VID:PID 0483:374B
Info : Target voltage: 0.018873
Error: target voltage may be too low for reliable debugging
Error: init mode failed (unable to connect to the target) # I got this same error with the nucleo, but it worked
in procedure 'program'
** OpenOCD init failed **
shutdown command invoked
make: *** [flash] Error 1
```
In the case above, it recognizes the device, but doesn't flash.
I'm unsure about how to start diagnosing. Is there anything in the schematic that's missing? I understand this is a lot to ask, but I'd appreciate any insight!
Cheers!
