nRF9160-DK - Boot Hangs On printk()

[johnwest]

Hello All,

Hoping this one is an easy one - have an image for the nRF9160-DK - it hangs unless I make a serial port connection - so, apparently - printk() is blocking waiting for the serial port connection.

How do you disable that?  Setting CONFIG_PRINTK=n didn't seem to work.

Thanks In Advance,
John W.

Your UART is disabled now ?
