Platform-Specific Instructions: nRF52840-Dongle
|
|
===================================
|
|
|
|
This is an adapted nrf52840\_dongle made to work with OpenSK.
|
|
|
|
The [nRF52840 Dongle](https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52840-Dongle)
|
|
is a platform based around the nRF52840, an SoC with an ARM Cortex-M4 and a BLE radio.
|
|
The kit is uses a USB key form factor and includes 1 button, 1 red LED and 1 RGB LED.
|
|
|
|
## Getting Started
|
|
|
|
To program the nRF52840 Dongle with Tock, you will need a JLink JTAG device and the
|
|
appropriate cables. An example setup is:
|
|
|
|
- [JLink JTAG Device](https://www.digikey.com/product-detail/en/segger-microcontroller-systems/8.08.90-J-LINK-EDU/899-1008-ND/2263130)
|
|
- [ARM to TagConnect Adapter](https://www.digikey.com/product-detail/en/tag-connect-llc/TC2050-ARM2010/TC2050-ARM2010-ND/3528170)
|
|
- [10pin TagConnect Cable](https://www.digikey.com/product-detail/en/tag-connect-llc/TC2050-IDC-NL/TC2050-IDC-NL-ND/2605367)
|
|
|
|
Then, follow the [Tock Getting Started guide](../../../doc/Getting_Started.md)
|
|
|
|
JTAG is the preferred method to program. The development kit has the JTAG pins exposed either
|
|
through the half-moons pads or, below the PCB, on a Tag-Connect TC2050 connector footprint.
|
|
You need to [install JTAG software](../../../doc/Getting_Started.md#optional-requirements).
|
|
|
|
## Programming the kernel
|
|
Once you have all software installed, you should be able to simply run
|
|
make flash in this directory to install a fresh kernel.
|
|
|
|
## Programming user-level applications
|
|
You can program an application via JTAG using `tockloader`:
|
|
|
|
```shell
|
|
$ cd libtock-c/examples/<app>
|
|
$ make
|
|
$ tockloader install --jlink --board nrf52dk
|
|
```
|
|
|
|
## Debugging
|
|
|
|
See the [nrf52dk README](../nrf52dk/README.md) for information about debugging
|
|
the nRF52840 Dongle.
