## Connections
|
|
|
|
* JTAG/SWD
|
|
* PA1: TDI
|
|
* PA13: TMS/SWDIO
|
|
* PA14: TCK/SWCLK
|
|
* PB3: TDO/TRACESWO
|
|
* PB5: TRST
|
|
* PB4: nRST
|
|
|
|
* USB USART
|
|
* PB6: USART1 TX (usbuart_xxx)
|
|
* PB7: USART1 RX (usbuart_xxx)
|
|
|
|
* +3V3.
|
|
* PB8 - turn on IRLML5103 transistor
|
|
|
|
## How to Build
|
|
|
|
```sh
|
|
cd blackmagic
|
|
make clean
|
|
make PROBE_HOST=blackpill
|
|
```
|
|
|
|
## How to Flash with dfu
|
|
|
|
* After build:
|
|
* 1) `apt install dfu-util`
|
|
* 2) Force the F4 into system bootloader mode by jumpering "BOOT0" to "3V3" and "PB2/BOOT1" to "GND" and reset (RESET button). System bootloader should appear.
|
|
* 3) `dfu-util -a 0 --dfuse-address 0x08000000 -D blackmagic.bin`
|
|
|
|
To exit from dfu mode press a "key" and "reset", release reset. BMP firmware should appear
