OpenThread can't find TRNG driver on nRF5340 #35512

Closed Gunzter closed 3 years ago

Gunzter commented 3 years ago

Describe the bug While trying to to build the Echo Server Example for the nRF5340DK board the compilation fail. With message "#error OpenThread requires an entropy source for a TRNG". The issue seems rooted in Devicetree to me, but I am a complete newbie to Zephyr-OS.

To Reproduce cd zephyrproject/zephyr west build -p auto -b nrf5340dk_nrf5340_cpuapp samples/net/sockets/echo_server -- -DCONF_FILE="prj.conf overlay-ot.conf"

Building this example would be the first step in a research project using TF-M and OpenThread, so unfortunately this issue looks like a showstopper.

Hi, OpenThread won't work for nRF5340 with vanilla Zephyr, i.e. it requires CryptoCell entropy which is only availalbe in the Zephyr-based nRF Connect SDK. Please use nRF Connect SDK instead.

Closing as per @rlubos' comment.

pawelosyp-hid commented 2 years ago

Hi all, Has anything changed in this topic? Driver to CryptoCell entropy or other solution for that? btw is it possible to make multiprotocol setup (BLE and OT) ? @rlubos

Nothing has changed in this regard.

btw is it possible to make multiprotocol setup (BLE and OT) ?

Yes, it is possible, but you also need NCS for that: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_multiprotocol_support.html#ug-multiprotocol-support

pawelosyp-hid commented 2 years ago

Are there any chances that it will be implemented in vanilla Zephyr? Or any part of that? Thanks for responce.

rlubos commented 2 years ago

I don't think there are plans for that as of today.
