Mesh Assert in unknown file and line 0 (probably a flash related issue)

Very sorry for the delayed response. How are you erasing flash & handling that? It is most likely related to this. The flash manager documentation explains this quite well. Also take a look at the flash manager API doc. Did you set up similar to how the light switch example does it? Do you have any code snippets I could look at?

okay, and what about the persistent storage issue?

Yes, I believe that may be the case.

are you saying i need generic on off along with lightness for lightness server to receive any messages?

Have you taken a look at this documentation? It seems that the light lightness actual state is bound to an instance of the Generic OnOff state. See the mesh model specifications for more info regarding this.

1. No this doesnt happe with the light switch example, i have simply added my lightness model in place of the generic on off, (haven't handled the bindings yet) but i just want the server to receive the client commands.

2. is generic on off required for lightness to work?? (i haven't implemented the bindings)

Have you noticed this issue with the standard light switch server example? What changes have you made to the code?

No I haven't tried with the new sdk, will test that. Ive made some changes in the light switch server example and testing it with lightness model that we wrote

Do you see the same issue when you try with mesh sdk v3.2.0? Are you testing with your own example or one of our examples?

RE: Mesh Assert in unknown file and line 0 (probably a flash related issue)

shreyab — Tue, 13 Aug 2019 14:33:33 GMT

yes, on multiple dev kits

RE: Mesh Assert in unknown file and line 0 (probably a flash related issue)

& have you received the same error on the other dev kit? Or is it only on one DK that you see this error?

I have done nothing different on the other dev kit (other than using a different JLink!)

Are you only receiving this error on one dev kit or multiple dev kits? On the DK where you do not receive this error, have you done anything differently there?

yeah, the output matches

nRF_SDK/nrf5SDKforMeshv310src/mesh/core/src/flash_manager.c:254 (discriminator 1)

and it goes away if i set PERSISTENT STORAGE to 0 but we need to use flash.. is this a bug?

Could you please double check this by running addr2line with your mesh assert, like shown here.
