# RNode Flasher
|
|
|
|
A web based firmware flasher for [Reticulum](https://github.com/markqvist/Reticulum) / [RNode_Firmware](https://github.com/markqvist/RNode_Firmware).
|
|
|
|
- It is written in javascript and uses the [Web Serial APIs](https://developer.mozilla.org/en-US/docs/Web/API/Web_Serial_API).
|
|
- It supports putting a device into DFU mode.
|
|
- It supports flashing `application` firmware from a zip file.
|
|
|
|
At this time, it does not support flashing bootloaders or softdevices.
|
|
|
|
## How does it work?
|
|
|
|
I wanted something simple, for flashing RNode firmware to a nRF52 RAK4631 in a web browser.
|
|
|
|
So, I spent a bit of time working through the source code of [adafruit-nrfutil](https://github.com/adafruit/Adafruit_nRF52_nrfutil) and wrote a javascript implementation of [dfu_transport_serial.py](https://github.com/adafruit/Adafruit_nRF52_nrfutil/blob/master/nordicsemi/dfu/dfu_transport_serial.py)
|
|
|
|
Generally, you would use the following command to flash a firmware.zip to your device;
|
|
|
|
```
|
|
adafruit-nrfutil dfu serial --package firmware.zip -p /dev/cu.usbmodem14401 -b 115200 -t 1200
|
|
```
|
|
|
|
The [nrf52_dfu_flasher.js](./nrf52_dfu_flasher.js) in this project implements a javascript, web based version of the above command.
|
|
|
|
There was an existing package called [pc-nrf-dfu-js](https://github.com/NordicSemiconductor/pc-nrf-dfu-js), however this repo had been archived and didn't appear to support the latest DFU protocol.
|
|
|
|
## How to use it?
|
|
|
|
- Open [index.html](./index.html) in your web browser.
|
|
- Put your device into DFU mode.
|
|
- Select a firmware file and click flash.
|
|
- Your device should reboot into the new firmware.
|
|
|
|
> Note: At this time, firmware hashes for RNode are not configured. This is next on the todo list.
|
|
|
|
## Device Support
|
|
|
|
The following list of devices are supported:
|
|
|
|
- RAK4631
|
|
|
|
## TODO
|
|
|
|
- support configuring eeprom with device signatures and firmware hashes
|
|
- support configuring tnc mode, also useful for the [transport node firmware](https://github.com/attermann/microReticulum_Firmware/commits/transport_node/)
|
|
- support other devices, such as ESP32/Heltec V3
|
|
- support flashing existing firmware files from api
