## Connections:
|
||||||
|
|
||||||
|
* JTAG/SWD
|
||||||
|
* PA1: TDI
|
||||||
|
* PA13: TMS/SWDIO
|
||||||
|
* PA14: TCK/SWCLK
|
||||||
|
* PB3: TDO/TRACESWO
|
||||||
|
* PB5: TRST
|
||||||
|
* PB4: SRST
|
||||||
|
|
||||||
|
* USB USART
|
||||||
|
* PB6: USART1 TX (usbuart_xxx)
|
||||||
|
* PB7: USART1 RX (usbuart_xxx)
|
||||||
|
|
||||||
|
* +3V3.
|
||||||
|
* PB8 - turn on IRLML5103 transistor
|

|
|
||||||
|
How to Build
|
||||||
|
========================================
|
||||||
|
```
|
||||||
|
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
|
||||||
|
|
||||||
|
|
||||||
|
10 pin male from pins
|
||||||
|
========================================
|
||||||
|
|
||||||
|
| PB3/TDO | PB7/RX | PB6/TX | X | PA1/TDI |
|
||||||
|
| -------- | ----------- | ---------- | ---------- | ------- |
|
||||||
|
| PB4/SRST | +3V3/PB8 SW | PA13/SWDIO | PA14/SWCLK | GND |
|
||||||
|
|
||||||
|
SWJ frequency setting
|
||||||

|
||||||
|
|
||||||
|
`mon freq 900k` helps at most
