nRF5340 BLE mesh samples don't work properly

[RAlexeev]

I tried to launch your example "Bluetooth: Mesh Light" using nRF5340 PDK and I failed. I followed this guide developer.nordicsemi.com/.../README.html. Also I tried to launch an example "Bluetooth: Mesh" (docs.zephyrproject.org/.../README.html) using nRF5340 PDK and I failed. I wrote out all combinations of samples in a table below which I tried to build and run, but all of them didn't work properly. But when I built the sample "Bluetooth: Mesh Light" for nRF52840 DK, then everything worked properly. The problems occurred only in the case of nRF5340 PDK.

Firmwares for application core in rows and firmwares for network core in columns.	Network core had firmware from sample /ncs/zephyr/samples/bluetooth/hci_rpmsg without any modification.	Network core had firmware from sample /ncs/zephyr/samples/bluetooth/hci_rpmsg with modification according to note from developer.nordicsemi.com/.../README.html, adding two lines to prj.conf: CONFIG_BT_CTLR_TX_BUFFER_SIZE=74 CONFIG_BT_CTLR_DATA_LENGTH_MAX=74

I used nRF Connect v3.4.1 Programmer to firmware a network core.

Explain to me, please, how to launch any sample of BLE mesh for nRF5340 PDK? Does the working sample exist at least?

Hi Roman, 

Please add the following code

    NRF_P0->PIN_CNF[0] = GPIO_PIN_CNF_MCUSEL_Peripheral << GPIO_PIN_CNF_MCUSEL_Pos;
    NRF_P0->PIN_CNF[1] = GPIO_PIN_CNF_MCUSEL_Peripheral << GPIO_PIN_CNF_MCUSEL_Pos;

in to ncs\v1.3.0\zephyr\boards\arm\nrf5340pdk_nrf5340\nrf5340_cpunet_reset.c as

I forgot to mention that I had warnings and errors in UART logs, but after it worked anyway.
