Well, it seems I am in your shoes Damian.io. I think my STM is blocked too.
Since it's the new adapter board for Gen2 , it's not exactly like the V3 boards, but connection is similar.
Ground, 3.3V, SWCLK and SWDIO
I tried .hex and .bin files with ST Nucleo, but I keep getting error messages when comparing after programming.
In LiveUpdates, I notice CoreState Blocked/Halted
Being my 2nd board, I would like to get to the bottom of this and not "replace STM" via programming..
When I execute the programming sequence, the connection is interupted and requires Restart before being able to re-connect.
Any ideas?

Thanks Kevin, I didn't think it was this complicated. I had a motor spinning in manual mode before the very slippery slope downhill.
Might have to rethink my project..But will persist for now with trying to reprogramme the adapter board. Zookeeper is keeping the flame burning with his motor in FOC mode!!
I thought, 4 wires, a ST Link, how hard can it be?

Re: HOWTO: Flashing with ST-Link v2 and OpenOCD (Open On-Chip Debugger)

I find the most painless way to flash these boards is with an ST-LINK V2, and a few other open-source command line tools.
My personal preference is a macOS environment, but most any *nix / Linux distribution will work, even the Linux subsystem in Winblows will do.
First connect the hardware with 3.3v, GND, DIO and CLK to the appropriate 4 pins on on both your STLINK-v2 dongle and the V3 board.
On macOS, Homebrew is my package manager of choice. I will use it's `brew install` in the examples below for getting the software needed for the flashing procedures. All of these tools are available for other subsystems, this same processes will apply to many other GNU/Linux based systems such as Arch, Debian, etc.
The software I'm recommending you use is OpenOCD (Open On-Chip Debugger) and telnet. They need to be installed for this process.
or similar pattern on linux etc.
I make an alias `st-oocd` in my systems .profile for running the following command to make it quick and easier. The paths might differ slightly between different software system distributions, but it won't differ much!
you will be prompted for your password to perform the `sudo` operation
SUCCESS!
Now OpenOCD has initiated a debug session to the STM32, leave this shell session running and in another shell session connect to the debug server with telnet
OpenOCD will respond;
In the active telnet session issue this command
If you have some blue-pill variant, or ??? may report back;
In this case `Device Security Bit Set` requires the STM32 must first be unlocked to program. The device must be halted before you can issue the unlock commands, it is best to reset and immediatly halt the device, and OOCD supplies a simple way, issue the `reset halt` command over telnet:
Now issue command;
So, we need to once again, soft reset and halt the stm32;
Now we you can continue programming! You will need to know the full pathname to the firmware files you wish to write.
Hex files include the offset address information.
Alternatively you may specify; to write with .bin binaries, but it will require that you include memory location offsets.
Keep in mind that you need to give specific paths to the firmware file(s).
We will issue on more soft reset;
At this point if all went well, we will see the 'ALIVE' led flashing it's little heartbeat.
Issue one last command over telnet to shutdown the connection.

Hi! Latest mainboard has TC2030 programming interface and I bought TC2030-MCP-NL-10 for it but I am not sure about pinout for it. Could someone help me connect ST-link to it?

Hi,the new boards use a new SWD connector. What type of connector should I use?

For the sake if it happens.
If you upload a empty project / overwrite the SWD pin config with something your chip/board can become in accesible.
To Solve:
- identify the reset pin on the device (chip)
- connect reset to GND
-Connect the ST-LINK and hit full erase in the application
- release the GND connection
The GUI will do a quick sweep and the chip is empty again.

flashed olimex from V2 board with android succesful with Zflash32 with arber instructions. Thanks

This push-pin SWD-connector is sort of proprietary. Its cheap to produce on PCB, but the connector is way too expensive. Please do not support this connector and just solder the wires on the pads. When done with flashing, unsolder the wires again when there is a risk of accidentally pulling on the soldered wires.
