Zephyr 2.4.0 with Async UART

[Canadian_EE]

Hi, 

   I am having the same problem as nRF9160 UART: Loosing data when RxData is split into 2 buffers (Async API) - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com) and ASYNC uart and UART_RX_RDY timeout - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com). I have tried the solution, namely modifying 

uart_nrfx_uarte.c

prj.config

However, I end up with this error

Ultimately, I would like this problem resolved. If I'm missing something obvious, please let me know.

The solution that was proposed is very old and hence definitely not API compatible with the newer ncsv2.4.0.

The pull request the other thread is showing seems to be merged. So I am confused that you are using ncsv2.4.0 and still have to patch the files with the PR changes? Shouldn't the changes be already in?

Do I need these additional lines in the prj.conf file to make UART ASYNC behavior work properly? 

"

CONFIG_UART_0_ASYNC=y

CONFIG_UART_0_NRF_HW_ASYNC=y

CONFIG_UART_0_NRF_HW_ASYNC_TIMER=1

CONFIG_NRFX_TIMER1=y

"

It seems that having these lines in the prj.config file helps it all run better. Which I do not understand. I would think that the ASYNC uart would either work or not work. Not varying levels of somewhat work.
