Adding NVS in zigbee sample

Question

We are making ZigBee product. The base we have took is from nrf connect sdk samples light_switch and coordniator example. everything works fine but we need to keep some information stored in NVS/flash.

Mainly for device list in network so that we can relate mac and short address and update it when rejoins. so that when coordinator restarts it has network device list.

Issue we are facing is that when we add nvs sample code it gives error

*** Booting nRF Connect SDK v3.5.99-ncs1-1 ***

[00:00:00.042,236] <err> flash_nrf: invalid address: 0x00100ff8:8
No key found, adding it at id 2

After research found its due to multi build
The nRF Connect SDK build system enables sysbuild by default, while Zephyr build system does not. You can select the build system default or choose to explicitly use --sysbuild or --no-sysbuild for your build configuration.

I am not sure how to fix it still
Any suggestion idea will be helpful!

Hi, 
 
 Thank you for sharing this, I was able to reproduce the scenario. 
 The problem is that ZIGBEE_SCENES uses settings, which uses NVS as the backend. 
 The application must then setup a specific storage partition that does not overlap with this settings partition. This can be done by setting a dedicated partition, lets name this "second_storage" here for simplicity: 
 // Comment out "original" partition name
//#define NVS_PARTITION storage_partition
#define NVS_PARTITION second_storage 
 Then we adjust the flash by placing this in the myproject/pm_static.yml: 
 app:
 address: 0x0
 end_address: 0xf3000
 region: flash_primary
 size: 0xf3000
settings_storage:
 address: 0xfe000
 end_address: 0x100000
 placement:
 align:
 start: 0x1000
 before:
 - end
 region: flash_primary
 size: 0x2000
sram_primary:
 address: 0x20000000
 end_address: 0x20040000
 region: sram_primary
 size: 0x40000
zboss_nvram:
 address: 0xf5000
 end_address: 0xfd000
 placement:
 after:
 - app
 align:
 start: 0x1000
 region: flash_primary
 size: 0x8000
zboss_product_config:
 address: 0xfd000
 end_address: 0xfe000
 placement:
 after:
 - zboss_nvram
 region: flash_primary
 size: 0x1000
second_storage:
 address: 0xf3000
 end_address: 0xf5000
 placement:
 align:
 start: 0x1000
 before:
 - end
 region: flash_primary
 size: 0x2000

Remember to delete your build folder and regenerate the project when changing the partition layout. 
 
 Could you try this and report back?
