Connections
|
||||||
|
====================
|
||||||
|
* PA0: User button to force system bootloader entry with reset (enter USB DFU)
|
||||||
|
|
||||||
|
* JTAG/SWD
|
||||||
|
* PC0: TMS/SWDIO
|
||||||
|
* PC1: TCK/SWCLK
|
||||||
|
* PC2: TDI
|
||||||
|
* PC3: TDO/TRACESWO
|
||||||
|
* PC4: SRST (NRST/System Reset)
|
||||||
|
* PC5: TRST (optional Test Reset)
|
||||||
|
|
||||||
|
* Green Led(ULED/PA4): Indicator that system bootloader is entered via BMP
|
||||||
|
|
||||||
|
* USB USART
|
||||||
|
* PA9: USART1 TX (usbuart_xxx)
|
||||||
|
* PA10: USART1 RX (usbuart_xxx)
|
||||||
|
|
||||||
|
How to Build
|
||||||
|
============
|
||||||
|
```
|
||||||
|
cd blackmagic/src
|
||||||
|
make PROBE_HOST=hydrabus
|
||||||
|
```
|
||||||
|
|
||||||
|
How to Flash the firmware with Windows
|
||||||
|
========================================
|
||||||
|
* After build:
|
||||||
|
* 1) 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.
|
||||||
|
* 2) Double click on "update_fw_usb_dfu_blackmagic.bat"
