Hi all,
I was going through the nRF Connect SDK tutorial and was trying to get the "Hello World" example running on a nRF5340-PDK (PCA10095, 0.8.0).
Before that I was already able to flash and test the "peripheral_lbs" example successfully. After erasing both chips with
- nrfjprog --eraseall
- nrfjprog -f NRF53 --coprocessor CP_NETWORK --eraseall
I followed the steps in the tutorial, created the needed files and started a project with:
- nrf5340pdk_nrf5340_cpuappns
- nRF Connect SDK Release V1.4.0
- Toolchain V1.4.0
My first question is, if it is correct, that I see 3 JLink CDC Uart Ports when I only connect one HW?
When building and running the example from SES V5.10d or when i manually build and flash it with west, I get the same result.
In the one terminal I can see the following that is repeatedly printed:
*** Booting Zephyr OS build v2.4.0-ncs1 *** Flash regions Domain Permissions 00 01 0x00000 0x08000 Secure rwxl 02 63 0x08000 0x100000 Non-Secure rwxl Non-secure callable region 0 placed in flash region 1 with size 32.

Comparing it to the expected output below, I can see that my Zephyr OS seems to be a newer version and that "Hello World" isn't printed on my output.
*** Booting Zephyr OS build v2.1.99-ncs1 *** Hello World!
Do you have an idea what could be going wrong?
Is the PDK too old or am I supposed to see this output on the not assembled USB J3?
Thank you in advance!

Pascal
