modem_shell sample comparison nrfSDK 2.9.0 with nrfSDK 2.6.1

[Roman Veselskyi]

Hello team,

I successfully migrate from the SDK 2.6.1 to 2.9.0. 

Now, I am trying to build the modem_shell sample for the nrf9160DK with nrf9160dk_nrf9160_ns.overlay file to support our custom PCB with nrf7000. Previously I successfully did it on the SDK 2.6.1

Sample location \ncs\v2.9.0\nrf\samples\cellular\modem_shell

The only change I did for both sample is to add the nrf9160dk_nrf9160_ns.overlay and CONFIG_WIFI_FIXED_MAC_ADDRESS="f2:01:d5:50:6f:52".

Build both samples with the next options:

 
As I understand this sample in SDK 2.9.0 doesn't support the sysbuild as there is no "sysbuild.conf" or "Kconfig.sysbuild" files am I correct? 

Now I have couple questions: 

1. I was able to build the sample with "No sysbuild" check mark in the build configuration but now I am having this error with WIFI which I don't have if I do the same but in the nrfSDK2.6.1

2. The amount of the used FLASH increased significantly in the nrfSDK 2.9.0

3. I don't understand why I need to set the MAC address if I am using only scan option?

Hello,

Could you share more information about the issue you are facing while trying to build using sysbuild? I tried building the modem_shell sample (without your overlay), and I was able to build it successfully. The image below shows the flash usage when using sysbuild.

Kind regards,
Abhijith

Ok I delete the .overlay file and try to build with the next options:


The error is the next:

In the .config.sysbuild I see that WIFI_NRF70=n, based on that I did assumption that sysbuild doesn't work for this sample.

Any updates?
