The STLINK V2 is a very cheap Chinese SWD programmer easily available on Internet.
This is the wiring to connect it to the Berta-H10 J2 PROG connector:
STLINK-V2 pin # | Berta-H10 J12 pin # | Signal name |
---|---|---|
2 | 9 | SWDIO |
3 | 8 | GND |
6 | 7 | SWCLK |
1 | 1 | RESET |
To use the STLINK V2 it is requested to install opencd on the Linux PC where is installed the H10 SDK by typing these commands:
sudo apt update
sudo apt install openocd
to launch the in-circuit type:
make flash PROGRAMMER=openocd OPENOCD_DEBUG_ADAPTER="stlink-dap"
...
