You can build an example using:
```sh
west build -b nrf52840dk_nrf52840
west build -b nrf52840dk/nrf52840
```
`nrf52840dk_nrf52840` selected the Nordic nRF52840 DK. For the older nRF52 DK with nRF52832, you can specify nrf52dk_nrf52832.
`nrf52840dk/nrf52840` selected the Nordic nRF52840 DK. For the older nRF52 DK with nRF52832, you can specify nrf52dk/nrf52832.
To get a list of all supported Zephyr targets, run `west boards`
To change zephyr platform settings use:
```sh
west build -b nrf52840dk_nrf52840 -t menuconfig
west build -b nrf52840dk/nrf52840 -t menuconfig
```
To build a different example, e.g. the `gatt_streamer_server`, set the EXAMPLE environment variable:
```sh
EXAMPLE=gatt_streamer_server west build -b nrf52840dk_nrf52840
EXAMPLE=gatt_streamer_server west build -b nrf52840dk/nrf52840
```
### 2. Flash Example

the other for the high level application logic. So both cores need to be programmed separately.
Using the nRF5340-DK for example allows debug output on both cores to separate UART ports.
For the nRF5340 a network core firmware is required, which one depends on the use-case.
With 2a and 2b two options are given.
With 2. an options is given.
### 1. Building the application
build using:
```sh
west build -b nrf5340dk_nrf5340_cpuapp
west build -b nrf5340dk/nrf5340/cpuapp
```
with debug:
```sh
west build -b nrf5340dk_nrf5340_cpuapp -- -DOVERLAY_CONFIG=debug_overlay.conf
west build -b nrf5340dk/nrf5340/cpuapp -- -DOVERLAY_CONFIG=debug_overlay.conf
```
### 2a. Using zephyr network core image
### 2. Using zephyr network core image
the `hci_rgmsg` application needs to be loaded first to the network core.
Configure network core by selecting the appropriate config file, for example `nrf5340_cpunet_iso-bt_ll_sw_split.conf`.
additionally it's required to increase the main stack size from

west build -b nrf5340dk/nrf5340/cpunet -- -DCONF_FILE=nrf5340_cpunet_iso-bt_ll_sw_split.conf

```
### 2b. Using Packetcraft binary network core image
for nrf5340 the latest netcore firmware is located at [sdk-nrf](https://github.com/nrfconnect/sdk-nrf/tree/main/lib/bin/bt_ll_acs_nrf53/bin)
to program it:
```sh
nrfjprog --program ble5-ctr-rpmsg_<version number>.hex --chiperase --coprocessor CP_NETWORK -r
```
