Configure logging module to go to uart

[dave]

Hi,

I am using the nrf9160 DK and want to set up logging to go to a uart.

I currently have logging enabled and can see it over the USB serial connection and can see logs being printed.

But I would like to change it to use a UART.  I have played with CONFIG_LOG_BACKEND_UART but am not seeing anything on the output

What needs to be configured to send logs ( like LOG_ERR) to a uart?

Hello Dave,

Could you check to see what the following nodes have defined for their UART?

Under your chosen node:

zephyr,console

zephyr,log-uart

From the source, the UART logging backend looks for either one of these nodes for where to direct output.

github.com/.../log_backend_uart.c

Thanks!

I was missing one of them, all is working now
