## Compilation
|
|
|
|
|
|
|
|
|
|
Clone this repository, then :
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
mbed deploy
|
|
|
|
|
mbed config root .
|
|
|
|
|
# set the desired compiler
|
|
|
|
|
mbed toolchain GCC_ARM
|
|
|
|
|
# set the desired board
|
|
|
|
|
mbed target NUCLEO_L073RZ
|
|
|
|
|
# set-up the compiler path if needed
|
|
|
|
|
mbed config -G GCC_ARM_PATH /opt/gcc-arm-none-eabi-7-2017-q4-major/bin
|
|
|
|
|
cp mbed_app.json.sample mbed_app.json
|
|
|
|
|
# modify lora.device-eui, lora.application-eui and lora.application-key in mbed_app.json
|
|
|
|
|
# or use the provided script to change them into the binary file
|
|
|
|
|
mbed compile --profile profiles/release.json
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Then you can use stm32flash or - may be better - a stlink interface to copy the generated .bin file onto the RAK811.

## Notes
|
|
|
|
|
|
|
|
|
|
### Tested boards
|
|
|
|
|
|
|
|
|
|
- MTB_RAK811
|
|
|
|
|
- NUCLEO_L073RZ + SX1272MB2xAS
|
|
|
|
|
|
|
|
|
|
### use STLink from a Nucleo board with the RAK811 board
|
|
|
|
|
|
|
|
|
|
From STlink CN4 Connector to RAK811 "shortest" connector (pin 1 at the same side of antenna connectors)
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
2 -> 3 (CLK)
|
|
|
|
|
3 -> 1 (GND)
|
|
|
|
|
4 -> 4 (DATA)
|
|
|
|
|
5 -> 2 (RST)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### rewire STLink on a cutted Nucleo board
|
|
|
|
|
|
|
|
|
|
From STlink CN4 Connector to Nucleo CN7
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
2 -> 15 (CLK)
|
|
|
|
|
3 -> 19,20,22 (GND)
|
|
|
|
|
4 -> 13 (DATA)
|
|
|
|
|
5 -> 14 (RST)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
From STLink CN3 Connector to Nucleo CN7 (stdio through USB)
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
rx -> 1 (USART4_TX)
|
|
|
|
|
tx -> 2 (USART4_RX)
|
|
|
|
|
```
|
