nRF5 SDK for Mesh / nRF52840 DK

[krajiiva]

Hello everyone,

I have following problem. I am trying to build a mesh network with the nRF52840 DK and the nRF52840 Dongle.

I am using the "nRF5 SDK for Mesh" (V4.2.0) with the "nRF5 SDK (V17.0.2)" and I am trying to make the lpn example of the "nRF5 SDK for Mesh" work.

I am able to compile the example but when it comes to linking then i get following errors:

build/lpn_nrf52840_xxAA_s140_7.0.1_Debug/obj/ses_startup_nrf_common.o: in function `afterInitialize':
undefined reference to `__RAM1_segment_end__'

I have already tried to change the settings of the Memory Segments and to add a Memory Map without any success. (These were succesful solutions for other users here)

Could you please tell me how I can get rid of these errors and how to make the example to work?

Thanks already.
Kind regards!

Hi,

The examples in nRF5 SDK for Mesh v4.2.0 are built for nRF5 SDK v16.0.0, so we can't guarantee that they'll work with v17.0.2, and I've already seen others with the same problem as you when trying to use v17.0.2. You should therefore use v16.0.0 instead.

If you still want to use v17.0.2 you should look at the release notes for v17.0.2 as well as the migration guide in order to figure out what was changed between the two releases. Someone had a similar problem when trying to build an example built for v17.0.0 with v17.0.2, so you could try out the solution by Simon to that problem, which can be found here.

Best regards,
