Legacy UART required for UART backend

[Anne van Rossum]

In `nrf_log_backend_uart.c` there is a reference to `./integration/nrfx/legacy/nrf_drv_uart.h`. I'm upgrading the system to use the Nordic provided backend, but it would be great if I can use something that will be supported for a while.

• What is the reason this uses legacy files?
• Can it be changed?
• What will be the timeline?
• Or would you recommend something completely different?

Hi,

This is just a legacy-layer that translates from the old API(nrf_drv) to the new API (nrfx). This is useful for backwards compatibility. But it’s the new nrfx drivers that are actually being used. See this post. I suggest keeping it as it is.
