Running Meshtastic on RAK WisBlock NRF52 based boards relies on the avaliability of the Arduono bootloader.
|
|
|
|
This process only needs to be performed once
|
|
|
|
This conversion requires the use of either a [DAPLink](https://daplink.io/) or [J-Link](https://www.segger.com/products/debug-probes/j-link/). The most reasonably priced and avaliable is the [RAKDAP1](https://store.rakwireless.com/products/daplink-tool).
|
|
|
|
1. Install [Python](https://www.python.org/downloads/)
|
|
2. Install [pyOCD](https://pyocd.io/)
|
|
|
|
```shell
|
|
pip3 install pyocd
|
|
```
|
|
|
|
3. Download the required bootloader: [WisCore_RAK4631_Board_Bootloader.hex](https://github.com/RAKWireless/WisBlock/releases/download/0.4.2/WisCore_RAK4631_Board_Bootloader.hex)
|
|
4. Connect the RAKDAP as follows:
|
|

|
|
5. Flash the bootloader
|
|
|
|
```shell
|
|
pyocd flash -t nrf52840 .\WisCore_RAK4631_Board_Bootloader.hex
|
|
```
|
|
|
|
6. Continue with the [normal instructions](/docs/getting-started/flashing-firmware/flashing-nrf52)
|
|
|
|
Alternate methods of flashing are outlined [here](https://github.com/RAKWireless/WisBlock/tree/master/bootloader/RAK4630).
