# Black Magic Probe Using Blue Pill
The project uses Visual Studio Code [Dev containers](https://code.visualstudio.com/docs/devcontainers/containers) for building [Black Magic Probe](https://github.com/blackmagic-debug/blackmagic) binaries.
## Flashing
```bash
# check if chip is accessible
st-info --descr
st-flash --reset write /blackmagic/src/blackmagic_dfu.bin 0x8000000
st-flash --flash=128k write /blackmagic/src/blackmagic.bin 0x8002000
```
## Wiring
| Blue Pill Probe | Pin | Function | Type | Target |
| --------------- | --------- | ------------------- | -------- | ---------------------------------------------------- |
| GND | GND | GND | | GND |
| SWCLK | 37 (PA14) | SWCLK/JTCK | SWD/JTAG | SWCLK (Serial Wire Clock) /TCK (Test Clock) |
| SWIO | 34 (PA13) | SWDIO/JTMS | SWD/JTAG | SWDIO (Serial Wire Data I/O) /TMS (Test Mode Select) |
| A15 | 38 | JTDI | JTAG | TDI (Test Data In) |
| B3 | 39 | JTDO | JTAG | TDO (Test Data Out) |
| B4 | 40 | nRST/JNTRST | JTAG | RESET/TRST (Test Reset) |
| B6 | 42 | UART1 TX | UART | UART RX |
| B7 | 43 | UART1 RX | UART | UART TX |
| A3 | 13 | UART2 RX (TRACESWO) | UART/SWD | |
## UDEV Rules
The below rules are borrowed from [the original source](https://github.com/blackmagic-debug/blackmagic/tree/main/driver).
```bash
# Black Magic Probe
# there are two connections, one for GDB and one for UART debugging
# copy this to /etc/udev/rules.d/99-blackmagic.rules
# and run sudo udevadm control -R
