I2C communication with nrf5340 custom board

[Vivek]

We are using nrf5340-dk to communicate with nrf5340 custom board and trying to search for the other sensors' addresses. There is secure mode and unsecure mode CPU. Which mode to try on? We could not detect the sensors I2C addresses.

Hi Markus,

one more question we are using toolchain version 1.5.1. In this there are 2 samples on inside nrf folder and another folder in zephyr.


when we use nrf samples from path "v1.5.1\nrf\samples\peripheral" and put our I2C sample to check I2C address. Its failed to run in non secure mode (cpuappns). but running in secure mode (cpuapp) not able to get I2C address when running in secure mode. 

Same sample when i am running from zephyr samples path its running properly.

for this i have few questions:-

> Which samples (nrf / zephyr) i have to run to check functionality of our custom board?

> As we connected my board using nrf5340 PDK board for programming but not able to see printk log on segger IDE debug console? how can i see log using PDK board.
I also tried hello_world samples code from zephyr. There is no printk log on console.

Can you please help for these queries?

As we are using Windows OS for our build environment.
