LPUART anomalous power consumption

Hi,

I am debugging the same sample, and I can see that the uart_callback_set() from the uart API is connecting with the api_callback_set() from the LPUART driver.

I can see that the rx_enable from LPUART driver is called:

Am I looking at something else?

Hello, we found the issue.

There was a mismatch in names between the device tree overlay and the binding in the code.

So the peripheral in the code was bound to the EUSART driver instead of the LPUART driver.

You can close the ticket.

Hello,

I wanted to share some results of the investigation we are carrying.

By trying to call uart_callback_set() function, the callback of the normal UART driver (uart_nrfx_uarte.c) is being called, not the callback of the lpuart driver (uart_nrf_sw_lpuart.c).

So it looks like the lpuart driver is being overridden by the normal uarte driver...?
