NRF9160 UART2

[jermi]

Hi nordic:

    NCS1.8.0 , I added UART2 to the NRF9160 LWM2M sample, but it cannot send and receive, but the same code is put into the NRF9160 UDP sample and it can work normally.
The sample log output on the 9160 LWM2M shows: 06 NRF_UARTE2 Secure SKIP；

Project files as attachments。

Please check where the configuration is wrong

thanks ！！

Hello jermi, can you please provide full project? I see that the UDP sample includes nrf\samples\nrf9160\udp\child_image\spm.conf
Have you tried to add this to your project?

Kind regards,
Øyvind
