Problems with nrf-mesh-freeRTOS-example

[David.Nam]

Hello. 

We are developing a Bluetooth mesh product using nrf52840.
To apply FreeRTOS, I downloaded and ran the nrf-mesh-freeRTOS example in Nordic Playground. Provisioning using the app worked well, but errors keep occurring when static provisioning using the provisioner example is operated.
The error is that in the code of heap_4.c, the prvInsertBlockIntoFreeList function did not get out of the first for statement and fell into an infinite loop.
If you reset the device when it falls into an infinite loop like this, it proceeds to the next provisioning step, and provisioning ends after one or two resets. Does anyone know why this is happening?

Please help. Thank you.

Hi.

Our FreeRTOS expert is out of office for a couple of days. I'll talk to him about this when he gets back.

Sorry about the inconvenience.

Hi.

OK. I see. 

Thank you.

Hi again! 

This might be due to the heap getting fragmented, if there is not enough heap reserved in FreeRTOSConfig.h file. Could you try increasing this and try again?

Hi.

Currently, the total heap size is 13312, and I changed this size to 26624 and tested it.

But nothing has changed.

Sincerely,

Ok, thanks!

Before seeing this error, did you make any changes to the example?

At first, I changed the example and tested it, but after finding out that there was a problem, I tested with the unchanged example. But I still had the same problem.

Sincerely,

David

Hi.

I've had some trouble reproducing the issue here. On my end the provisioning works as it should.

Are you sure that there hasn't been made any changes to some other files in your Mesh SDK that might cause this?
If it's possible; could you test this again with a fresh download of the nRF5 SDK for Mesh?
