PERSISTANT_STORAGE with dongle w/ mesh SDK crashes.

[Ryan]

I am trying to get 2 of the nRF52840 dongles provisioned on a mesh network (client + server).  (versions nRF5_SDK_15.3.0_59ac345 / nrf5SDKforMeshv310src)

I am using examples from the light switch example + made adjustments to the button and LED assignments.  Also, I had to add defines for LED_START/LED_END to the PCA10059 config because they are missing.

---

I also added both the additional lines needed in flash_placement.xml:

To FLASH segment:
<ProgramSection alignment="4" keep="Yes" load="Yes" name=".nrf_mesh_flash"  inputsections="*(SORT(.nrf_mesh_flash.*))" address_symbol="__start_nrf_mesh_flash" end_symbol="__stop_nrf_mesh_flash"/>

To RAM segment:
<ProgramSection alignment="4" keep="Yes" load="No" name=".nrf_mesh_ram"  inputsections="*(SORT(.nrf_mesh_ram.*))" address_symbol="__start_nrf_mesh_ram" end_symbol="__stop_nrf_mesh_ram"/>

---

An error is being thrown on line 108 of mesh_config_backend.c by NRF_MESH_ASSERT:

NRF_MESH_ASSERT(p_file != NULL && p_file->p_backend_data != NULL);

--

...which is causing the sleep_forever() which lights up all the LED's

---

When I disable PERSISTANT_STORAGE by setting this = 0 in the Preproc Defs I am able to run the dongle firmware (both client/server) 

I am able to see the nodes in IOS rF Mesh App, but when I try to identify it just hangs with the spinner. (prob because persistence is disabled.)

Can you guys please send me a link to any alpha/beta repos that might have a fix for this? It looks like the mesh_config_entry (p_entries) are maybe not getting configured properly.

Is there really no way send console output through the UART via serial on the USB port? Thats all I need for now, dont need j-link debug  and all that..

Thanks,
Ryan

The nrf Connect application reports that my application size is 97296 bytes, so I have tried to adjust the linking paramerters to the following

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x100000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x40000

FLASH_START=0x26000

FLASH_SIZE=0x17C10

RAM_START=0x2003DC10

RAM_SIZE=0x23F0

but when I do this I am getting compile errors:
