# Program rtl8170 (RtlDuino) with STM32 Discovery Board
|
|
|
|
|
|
|
|
|
|
1) Disconnect CN3 Jumpers (inside 'ST-LINK DISCOVERY' label)
|
|
|
|
|
2) Connect to SWD (CN2) pins with jumpwires to rtlduino board (see rtlduino-pinout.png):
|
|
|
|
|
Pin 2 <> CLK
|
|
|
|
|
Pin 3 <> GND
|
|
|
|
|
Pin 4 <> TMS
|
|
|
|
|
(Pin 5) <> TRST
|
|
|
|
|
3) Connect any 5V pin on STM board to 5VDD
|
|
|
|
|
4) Install OpenOCD >= version 0.9, and install gcc-arm-none-eabi
|
|
|
|
|
5) git checkout https://bitbucket.org/rebane/rtl8710/src
|
|
|
|
|
6) Replace in Makefile "interface/stlink-v2-1.cfg" with "interface/stlink-v2.cfg"
