Facing issues because of Version Update

[Mr.NCK]

HI

Recently, I had updated the toolchain manager in NRF connect desktop. Now I have version V0.10.0. I think, at the time of the tool manager update my NRF connect SDK also automatically gets updated. Now my own developed applications are not working properly.  I have tried the BLE-based application on NRF5340 DK. The BLE advertisement was not happening. In previous same application was working fine 

Thanks & Regards

Hi,

Updating the Toolchain Manager will not affect any nRF Connect SDK installations, so it would be very strange if that is the source of your issues.

You said that your own developed applications are not working, does that mean that the sample applications are still working as expected?

Since you are saying that BLE-based applications are not working on the nRF5340, it may be an issue with building the hci_rpmsg child-image.
Could you check the build log to ensure that hci_rpmsg is built properly? Are you seeing any warnings?

Yes, But now I have tried with all samples like Blinky, Hello world also not working

I have checked clearly. The child image was built correctly without any warnings or errors.

Before, I have used  NCS version 1.5.0 

Then, I have also checked with NCS version 1.7.0 by creating a new application. Even in this, the same issues are followed

Can you try to build zephyr/samples/bluetooth/hci_rpmsg with the board nrf5340dk_nrf5340_cpunet, and flash it?

Then build and flash zephyr/samples/bluetooth/peripheral_hr with the board nrf5340dk_nrf5340_cpuapp?

Does that start advertising?

Hi,

Thank You So Much, It's working fine. I need some suggestions from you prior I have created the child image from embedded seggger ide and flashed via cmd prompt using "west flash -- erase". I need to know this  way is correct or not

Also, I need to know maximum of the work was finished with the NCS version 1.5.0 Which is best to continue with the same version or else upgrade to version 1.7.0

I think that should work, but if you want to be sure, you can build on the command line as well, as explained in Building on the command line.
For a cpuapp application with a child-image, running these two commands in the application folder is usually enough and will build and flash both cores:

west build -b nrf5340dk_nrf5340_cpuapp
west flash --erase

Also, I need to know maximum of the work was finished with the NCS version 1.5.0 Which is best to continue with the same version or else upgrade to version 1.7.0

If you have already completed a lot of your work on v1.5.0, and you have no specific reason to upgrade to v1.7.0, you can stay on v1.5.0. I would only strongly recommend upgrading for new projects, or if you need a bugfix, improvement or new feature found in a newer version.
