nRF5340 support in nRF Connect SDK and Zephyr

[Einar Thorsrud]

Q: How can I play with making firmware for nRF5340 before it is supported in nRF Connect SDK?

[Einar Thorsrud]

A: It will be supported in nRF Connect SDK real soon. If you are impatient, you can use Zephyr master. If you want BLE support, you should use this PR.

Update:

nRF53 Support is available in nRF Connect SDK as of November 19^th.

All future versions (master and future release tags) will have support for nRF5340.

The commit SHA corresponding to the first availability is ec6aa43102dbc8207d9dc95b4133731d39aff0c9.

To access this specific, first version

If you do not have a copy of NCS locally

west init -m https://github.com/NordicPlayground/fw-nrfconnect-nrf --mr ec6aa43102dbc8207d9dc95b4133731d39aff0c9

If you already have a copy on NCS locally

1. cd ncs/nrf
2. git fetch ncs
3. git checkout ec6aa43102dbc8207d9dc95b4133731d39aff0c9
   1. (optional, create a branch) git checkout -b <<branch_name>>
4. west update

To access the latest development version of nRF Connect SDK (master)

If you do not have a copy of NCS locally:

west init -m https://github.com/NordicPlayground/fw-nrfconnect-nrf

If you already have a copy of NCS locally:

1. cd ncs/nrf
2. git fetch ncs
3. git checkout ncs/master
4. west update

These instructions are also part of the Nordic nRF Connect SDK documentation.

How to create the precompiled examples in the nRF5340 getting started:

cd samples/bluetooth/hci_rpmsg/
west build -b nrf5340_dk_nrf5340_cpunet
west flash

cd samples/bluetooth/peripheral_hr
west build -b nrf5340_dk_nrf5340_cpuapp 
west flash

Thanks Kenneth! I couldn't figure out what to flash on the network core until I read your post here. Not sure if we have that anywhere in the documentation.

I was able to successfully build and run both the Peripheral UART (ncs\nrf\samples\bluetooth\peripheral_uart) and Throughput (ncs\nrf\samples\bluetooth\throughput) examples on the nRF5340 PDK.
