SDK 15.2 NRF_LOG via uarte with the regular uart

[Matts]

Hi.

So I'm trying to configure my SW to use two uarts (as I've understood that uarte and uart are separate modules that can be used at the same time).

As the app_uart seems to follow same configuration as NRF uart logging, I'm using the uart0 via nrfx_uart -interface. I'm using different pins than ones for NRF_LOG. However when ever I try to transfer via uart0, I get error trace and reset:

<error> app: Fatal error
<warning> app: System reset

I tested this also via uarte0 and same thing.

So is there valid configuration available for this?

Hi,

You cannot use the UART and UARTE at the same time as long as these are not different instances.

It is possible only with the chip nrf52840 - it has UART0/UARTE0 and UARTE1.
