# Firmware BMP for STM32F401/stm32f411 MiniF4 aka BlackPillV2 boards
|
||||
|
||||
Allows the use of BlackPillV2 as a Black Magic Probe
|
||||
|
||||
https://github.com/WeActTC/MiniSTM32F4x1
|
||||
|
||||
## 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
|
||||
====================================
|
||||
https://github.com/blackmagic-debug/blackmagic/pull/783#issue-529197718
|
||||
|
||||
`mon freq 900k` helps at most
