Make MCUboot run without enabling serial

[Eirik Aa]

Im trying to recreate the example from:

https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/hardware-design/posts/measuring-psm-idle-current-on-the-nrf91-dk

But also having MCUboot appplication compiled in.

But is I disable the serial port on SPM and my application project then board seems to go into a loop on only running MCUboot, and MCUboot still uses the serial port. Anyone have any insight into how to recreate the same results in the above blog post but still compliling application + spm + mcuboot?

Are you sure you have disabled the serial port? I have added CONFIG_SERIAL=n to SPM and my own custom project and the device no longer prints printk() or printf() to the Link Monitor.

Thanks. Then I will start figuring out of the prolem is elsewhere. I will get back with my finding :)

A quick question I would have is, did you maybe put the CONFIG_SERIAL=n into the wrong prj.conf? I sometimes mix up the folder files when I'm working across multiple application folders as they are all called the same thing in every sample and custom application folder.
