19. Using a genuine ST‐Link
For this I used the st-link part from a cheap Nucleo board (~20 Euros).
I had no success with st-link clones. Genuine worked.
The left part is the st-link part and you need to remove those two jumpers,
to work with external devices.
Those are the SWD pins and the pinout table (top pin is #1).
Red cable does not provide power to the dashboard.
It measures the voltage of the target's 3.3V line.
You have to connect this at the dashboard's SWD 3.3V pin
and give power from the main connector.
Yellow, Black & White are SWCLK, GND & SWDIO respectively.
Green is the reset (NRST) and you need to connect this to the C45 capacitor.
Connection sequence:
Power the dashboard, plug in st-link's USB,
touch & hold C45 continuously and run the scripts.
After successful flash, power cycle the dashboard.
