Add 96Boards Carbon as a probe host
The carbon contains two SoCs, an STM32 (host) and an nRF51 (BLE). The STM32 implements the probe and allows the board to reprogram its own radio firmware!

Connections
|
||||
===========
|
||||
|
||||
The pinout for the programmer is concentrated within a single part of
|
||||
the Low Speed connector. The target control pins at the even pins 2
|
||||
through 16 with UART on LS-03 and LS-05.
|
||||
|
||||
The pinout for the programmer allows a Carbon to program another Carbon
|
||||
(either the STM32 or the nRF51) with adjacent pins from LS-06 to LS-12.
|
||||
The order matches that of the SWD pins for easy hook up.
|
||||
|
||||
JTAG/SWD
|
||||
--------
|
||||
|
||||
* LS-02 (PB12): TDO/TRACESWO
|
||||
* LS-04 (PB15): TDI
|
||||
* LS-06 (PB14): TMS/SWDIO
|
||||
* LS-08 (PB13): TCK/SWCLK
|
||||
* LS-10 : GND
|
||||
* LS-12 : Vcc
|
||||
* LS-14 (PC3) : TRST (optional test reset)
|
||||
* LS-16 (PC5) : SRST (system reset)
|
||||
|
||||
LEDs
|
||||
----
|
||||
|
||||
* USR1 (green): Debug activity indicator
|
||||
* USR2 (green): UART activity indicator
|
||||
* BT (blue) : Error indicator
|
||||
|
||||
UART
|
||||
----
|
||||
|
||||
* LS-03 (PA2): UART TX
|
||||
* LS-05 (PA3): UART RX
|
||||
|
||||
How to Build
|
||||
============
|
||||
|
||||
cd blackmagic
|
||||
make clean
|
||||
make PROBE_HOST=96b_carbon
|
||||
|
||||
Flashing using dfu-util
|
||||
=======================
|
||||
|
||||
Connect to the USB OTG socket on the Carbon and force the device into
|
||||
system bootloader mode by holding down the BOOT0 switch whilst pressing
|
||||
and releasing the RST switch. To program the device try:
|
||||
|
||||
sudo dfu-util -d [0483:df11] -a 0 -D src/blackmagic.bin -s 0x08000000
|
||||
|
||||
Self-programming
|
||||
================
|
||||
|
||||
A Carbon is capable of self-programming its own nRF51 by connecting two
|
||||
jumper wires from LS-06 to BLE_SWD-4 (DIO) and LS-08 to BLE_SWD-3 (CLK).
