Hi Simon,

Thanks for responding.

Yes indeed it is returning an INVALID_STATE. This is because I had previously initialized it.
In my application I use the UART interface for a custom protocol, so I initialize a uart event handler.
When log_init() is called, it also tries to initialize the same UART interface with it's own handler. This is what causes the crash.

The log uart_event handler would clash with my custom protocol handler as they would both contend for the same resource.

So I've resorted to using printf statements with RETARGET_ENABLE set to 1. This causes my print logs to appear on the UART interface without disrupting my custom protocol.

Thank you.

Does nrf_drv_uart_init() return NRFX_ERROR_INVALID_STATE (=0x8)? Have you already initialized it? Try setting a breakpoint in the function and see where it is initially called from.

What example are you using?

Best regards,

Simon
