Adding NVS in zigbee sample

[Dhaval Dalvadi]

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 ***
[00:00:00.020,416] <err> flash_nrf: invalid address: 0x00100ff8:8

[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!

[Håkon Alseth]

Hi,

 

Can you share how you are reproducing this issue?

When altering the partition layout, it is important that you re-generate the build (ie. delete the build folder, then re-configure) - this is to ensure that the partitions are generated within the address space of the chosen device.

Your address space seems to be out-of-bounds.

 

Kind regards,

Håkon

[Dhaval Dalvadi]

Hi Hakon 
I am not sure where to alter partition layout 
in nvs example it used to be mentioned in device tree but if have used zigbee samples 
not able to find where to add nvs partition or if it has then how to modify it 

[Håkon Alseth]

Hi,

 

The layout is generated based on the configuration.

Can you please share how to recreate this scenario?

 

Kind regards,

Håkon

Hi,

I tried to reproduce with sample you can use coordniator example with below prj.conf

I found if I comment 

CONFIG_ZIGBEE_SCENES=y

 it works fine

but I will need that so how can I fix it any idea?

[Håkon Alseth]

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?
