MCUBOOT DFU Over Bluetooth Fails During Firmware Download – Need Help

[Dalvadi Anil]

"I'm trying to perform DFU using MCUBOOT over Bluetooth. The device enters DFU mode and connects successfully, but when I start the firmware download, I get an error:

Hi Dalvadi,

it seems to me that your pm_static.yml is configured wrong.
The nRF52840 has 1MB flash so the max address usable is 0xFFFFF.
According to your pm_static your secondary partition starts at 0xFD000 and goes till 0x1EE000 which already exceeds the 1MB flash.

May I ask how you got this pm_static?

Kind regards
Johannes

Hi Johannes,

Thank you for your suggestion. You are correct that the secondary partition exceeds the 1MB flash limit of the nRF52840. I am using additional storage for data logging, and I also need to support DFU updates.

Can you provide a correct pm_static.yml configuration that includes some storage space and supports DFU updates while staying within the 1MB flash limit of the nRF52840?

Best regards,
Dalvadi

Hi Dalvadi,

in your case I think it should look something like this:

  size: 0xc000
  region: flash_primary

mcuboot_pad:
  address: 0xc000
  size: 0x200

mcuboot_primary:
  address: 0xc000
  size: 0x72000
  region: flash_primary

app:
  address: 0xc200
  size: 0x71E00
  region: flash_primary

mcuboot_secondary:
  address: 0x7e000
  size: 0x73000
  region: flash_primary

second_storage:
  address: 0xf1000
  size: 0x4000
  region: flash_primary
  placement:
    align:
      start: 0x1000
    before:
    - zboss_nvram

zboss_nvram:
  address: 0xf5000
  size: 0x8000
  region: flash_primary
  placement:
    after:
    - second_storage
    align:
      start: 0x1000

zboss_product_config:
  address: 0xfd000
  size: 0x1000
  region: flash_primary
  placement:
    after:
    - zboss_nvram

settings_storage:
  address: 0xfe000
  size: 0x2000
  region: flash_primary
  placement:
    align:
      start: 0x1000
    before:
    - end

sram_primary:
  address: 0x20000000
  end_address: 0x20040000

Hi Johannes,

I try using this but not work for me getting this error.

-- Found partition manager static configuration: /Users/nistantritech/Documents/Project/firmware_project/hazelnut_zigbee-master/ESPZIG_Single_Project/pm_static.yml
Partition 'zboss_nvram' is not included in the dynamic resolving since it is statically defined.
Partition 'zboss_product_config' is not included in the dynamic resolving since it is statically defined.
Partition 'settings_storage' is not included in the dynamic resolving since it is statically defined.
Partition manager failed: Incorrect amount of gaps found in static configuration. There must be exactly one gap in the static configuration to support placing the dynamic partitions (such as 'app'). Gaps found (0): The most common solution to this problem is to fill the smallest of these gaps with statically defined partition(s) until there is only one gap left. Alternatively re-order the already defined static partitions so that only one gap remains.

Hi Dalvadi,

ok, so far I haven't seen this error.

Could you try this partition config instead?

Alternatively you could remove pm_static.yml, rebuild your project and take a look at build/partitions.yml. This is the automatically generated partition config. You can than copy this file, rename it and use it as a new pm_static.yml and make changes according to your needs

Kind regards,
Johannes
