Partition manager and FOTA

[Nathan Bourgeois]

Hi,

I have a nrf52833 with MCUBoot and BLE, I am using NCS v3.0.1. 

I need also a custom NVS partition to store user data, so i create a data_partition for this purpose.

Now to the fun part, i am having trouble with the partition manager when i'm using FOTA. My project works fine but when i wanted to add FOTA, i got an flash error everytime i try an update. After digging a bit, i understand that is a write error in the smcuboot_secondary partition. 

The mcuboot_secondary partition start at address 0x41800 and don't respect the 0x1000 page size of the nrf52833 which explain why i couldn't update (cf pm_static.yml.working)

app:
  address: 0x7200
  end_address: 0x41800
  region: flash_primary
  size: 0x3a600
data_storage:
  address: 0x7c000
  end_address: 0x7e000
  placement:
    align:
      start: 0x1000
  region: flash_primary
  size: 0x2000
mcuboot:
  address: 0x0
  end_address: 0x7000
  placement:
    align:
      end: 0x1000
    before:
    - mcuboot_primary
  region: flash_primary

mcuboot_pad:

  end_address: 0x7200

mcuboot_secondary:
  address: 0x41800
  end_address: 0x7c000
  placement:
    after:
    - mcuboot_primary
    align:
      start: 0x1000
  region: flash_primary
  share_size:
  - mcuboot_primary
  size: 0x3a800
settings_storage:
  address: 0x7e000
  end_address: 0x80000

sram_primary:
  address: 0x20000000
  end_address: 0x20020000
  region: sram_primary
  size: 0x20000

I edit the file to place it at 0x41000 and decrease the image size (cf pm_static.yml.not_working)

sram_primary:
  address: 0x20000000
  end_address: 0x20020000
  region: sram_primary
  size: 0x20000

But it don't boot anymore, i can't get anything on RTT or serial or anything that make me believe the bootloader successfully start the image.

Do you know what is happening ? 

Best regards,

Nathan

Hello Nathan,

he mcuboot_secondary partition start at address 0x41800 and don't respect the 0x1000 page size of the nrf52833 which explain why i couldn't update (cf pm_static.yml.working)

Just to confirm, this start address was set automatically in your build, and not by you? I'm also surprised it didn't adhere to the flash page aligment requirement.

Please try the following: 

- delete the build folder

- make a backup of your pm static file, then create a new one that only defines the settings_storage and data_storage partition. This allows the PM to dynamically create the rest.

- Try DFU again.

Best regards,

Vidar

Hi Vidar,

I did let the partition manager do it's job and then copy the content of partitions.yml to my pm_static.yml

Following your instructions, i only define settings_storage and data_storage in my pm_static.yml like this : 

settings_storage:
  placement:
    before: 
    - end
  region: flash_primary
  size: 0x2000
data_storage:
  placement:
    before: 
    - settings_storage
  region: flash_primary
  size: 0x2000

And i got this build error :

Look correct but same issue the firmware don't seem to start.

I don't see anything wrong with the memory layout now. Do you have logging over UART available on this board? If not, can you try to attach the debugger to see where it the bootloader it hangs?

Hello,

This indicates that the bootloader did not find a bootable image. Did you program the merged.hex file generated by your build which contain both the application and bootloader?

[Nathan Bourgeois]

Hi Vidar,

Sorry for the late answer, i found and fix my problem.

The issue was my image was more than 95% occupency and it is a know issue with mcuboot. As soon as i turn off log for saving memory, the program was booting as expected.

I close this ticket.

[Vidar Berg]

Thank you for update. I'm glad to hear that it works now. It is on our to do list to catch this issue at build time.
