NCS 3.1.0: nrf5340 network image version is set to 0.0.0.0

Hi,

If I build the extxip_smp_svr sample app for the nrf5340dk board. The network image firmware version is set to 0.0.0.0.

To reproduce the issue, do the following:

1) Create a VERSION file in the root directory of the extxip_smp_svr example with the following data:

VERSION_MAJOR = 1
VERSION_MINOR = 2
PATCHLEVEL = 3
VERSION_TWEAK = 4
EXTRAVERSION =

2) Build the project for nrf5340dk.

3) Inspect the image header of the network image. It has a 0.0.0.0 firmware versions. The internal and external image .bin files have the correct firmware version.

See the attached screenshots.

Hi Ronald, 
I would suggest to take a look at this similar ticket: nRF5340 netcore firmware version 

You can also find the information about netcore version in the documentation here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/tfm/tfm_psa_template/README.html#updating_the_network_core_nrf5340_only

Please try with the CONFIG_FW_INFO_FIRMWARE_VERSION configuration for the netcore image, and let us know if you still have any issue.

Hi Hung,

The CONFIG_FW_INFO_FIRMWARE_VERSION is the image firmware version that has a range of 0 to 32766.

The version I'm talking about is the MCUboot image version that's added to the beginning of the image file when the image is signed by the imgtool.py script. The version format of the image version is <major>.<minor>.<patch>.<tweak>.

After looking around, I found that the CONFIG_SECURE_BOOT_MCUBOOT_VERSION option sets the image version of the net core image.

Hi Ronald, 
The netcore update is a bit special so I don't think it use the same format as the MCUboot image version (note that the actual update of the netcore is not done by MCUBoot but the b0 on the network core) 

As far as I know this CONFIG_SECURE_BOOT_MCUBOOT_VERSION  is for the MCUboot image, not the network image.
