Switch LoRa concentrator MCU to DFU mode (USB gateway)
|
||
|
|
======================================================
|
||
|
|
|
||
|
|
|
||
|
|
## 1. Introduction
|
||
|
|
|
||
|
|
This software is used to switch the concentrator in DFU mode in order to program
|
||
|
|
its internal MCU.
|
||
|
|
|
||
|
|
## 2. Usage
|
||
|
|
|
||
|
|
```console
|
||
|
|
./boot -d /dev/ttyACMx
|
||
|
|
```
|
||
|
|
|
||
|
|
## 3. Program binary file into internal MCU flash memory
|
||
|
|
|
||
|
|
Download the dfu-util tool from here: http://dfu-util.sourceforge.net
|
||
|
|
|
||
|
|
```console
|
||
|
|
sudo dfu-util -a 0 -s 0x08000000:leave -t 0 -D ../mcu_bin/xxx_fwm_xxx.bin
|
||
|
|
```
|
||
|
|
|
||
|
|
This will automatically exit the DFU bootloader mode, the concentrator is now
|
||
|
|
ready to be used.
