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

[shreyab]

Hello,

I am getting error -

t:      17532>, app_error_weak.c,  108, Mesh assert at 0x0002CF9E (:0)

I debugged it, it took me to the flash_manager.c - line 254 which is

NRF_MESH_ASSERT(p_manager->config.p_area[i].metadata.page_index == i);

Any help is appreciated.

I would like to point out, i am not getting this error on all dev kits, on one of the dev boards, it got provisioned.

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

[shreyab]

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?

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?

[shreyab]

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

[Bjørn Kvaale]

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

[shreyab]

yes, on multiple dev kits

[Bjørn Kvaale]

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?

[shreyab]

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

[Bjørn Kvaale]

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

[shreyab]

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)
