## Flashing
|
|
### Connections
|
|
To flash using the STM32 ROM bootloader on the board, use the provided UART-USB
|
|
bridge and connect it to the *Config* port. The *Config* port pinout is the
|
|
following:
|
|
|
|
```
|
|
--------------- ---------------
|
|
| 1 2 3 4 5 6 | | x x x x x x |
|
|
--------------- ---------------
|
|
Config Addon
|
|
|
|
1: RST
|
|
2: VCC
|
|
3: RX1
|
|
4: TX1
|
|
5: Boot0
|
|
6: GND
|
|
```
|
|
|
|
### STM32 Loader
|
|
To flash RIOT on the board, after connection the UART-USB bridge, just run:
|
|
```
|
|
BOARD=lobaro-lorabox make flash
|
|
```
|
|
This uses the stm32loader script to erase the memory and flash it interfacing
|
|
with the STM32 ROM bootloader.
|
|
|
|
### Lobaro Tool
|
|
Another way of interfacing with the STM32 ROM bootloader is using the **Lobaro Maintenance Tool** provided
|
|
[online](https://www.lobaro.com/lobaro-maintenance-tool/) for free for Linux,
|
|
Mac & Windows. It allows flashing and accessing the UART.
|
|
|
|
|
|
|
|
## Connecting via Serial
|
|
The default UART port is the USART1, the same that is used for flashing, so it
|
|
is available on the *Config* port. The default port is /dev/ttyUSB0. To access
|
|
the port run:
|
|
```
|
|
BOARD=lobaro-lorabox make term
|
|
```
|
|
**Note:** If you want to access the port with a different application please
|
|
keep in mind that RTS must be set to '0' and DTR to '1' as the provided UART-USB
|
|
bridge seems to invert this lines.

## SX1272 radio
|
|
Please note that the board has a Semtech SX1272 radio. This means that when the
|
|
semtech-loramac package or the sx127x driver are used the correct driver version
|
|
(sx1272) must be selected.
