Getting error while build configuration for gsm_modem sample code

[pulkit]

I am trying to interface nrf52833 devkit with BG95 devkit using PPP connection. For this I am using gsm_modem sample code. But when I am getting error while build configuration, as mentioned in the image. There are changes done in the sample code still getting this error. Is there anything I am doing wrong to build this sample code.

Hi,

What changes have you made to the sample?

Have you made an overlay file for the nRF52833 DK where you added the modem, similar to the existing overlay files?

I recommend looking at Troubleshooting the devicetree in our nRF Connect SDK Intermediate course on DevAcademy and Zephyr's Troubleshooting devicetree in the documentation for tips on how to fix devicetree issues.

Best regards,
Marte

Thanks for the response, I will try this and let you know if I need any help further.

I have created an overlay file as mentioned below

Can you please suggest what are the necessary things we need to write in overlay file for nrf52840 or nrf52833.

Hi,

The devicetree looks correct. Are you seeing any issues when testing with the modem?

Best regards,

I am able to build the "gsm_modem" sample code, When I am checking the logs, sometimes it shows "Network connected" but most of the times logs stops at "Initializing PPP to use uart@40028000" also attaching the log in images. Only things I have added/changed in code is overlay file for nrf2840 devkit and build configuration for nrf52840. Network is proper as I have checked BG95 modem network using AT commands.

Also to get the information(Manufacturer, Model, Revision etc.) logs I need to power cycle the BG95 after everytime I reboot the nrf52 device.

Here is the code I am using
