Hi, You are using pm_static.yml for all partitions. The whole point of the partition manager is that you should not have to deal with that yourself. You can only use pm_static.yml to increase the mcuboot…

Have you made any changes to the pm_static.yaml file?

Hello Susheel Nuguru,

I was able to debug this further,

The below is the static file which works for me:

app:
  address: 0xc200
  end_address: 0x7e000
  region: flash_primary
  size: 0x71e00
external_flash:
  address: 0x0
  end_address: 0x100000
  region: external_flash
  size: 0x100000
mcuboot:
  address: 0x0
  end_address: 0xc000
  placement:
    before:
    - mcuboot_primary
  region: flash_primary
  size: 0xc000
mcuboot_pad:
  address: 0xc000
  end_address: 0xc200
  placement:
    before:
    - mcuboot_primary_app
  region: flash_primary
  size: 0x200
mcuboot_primary:
  address: 0xc000
  end_address: 0x7e000
  orig_span: &id001
  - app
  - mcuboot_pad
  region: flash_primary
  size: 0x72000
  span: *id001
mcuboot_primary_app:
  address: 0xc200
  end_address: 0x7e000
  orig_span: &id002
  - app
  region: flash_primary
  size: 0x71e00
  span: *id002
mcuboot_secondary:
  address: 0x0
  device: IS25
  end_address: 0x72000
  region: external_flash
  size: 0x72000
settings_storage:
  address: 0x7e000
  end_address: 0x80000
  placement:
    before:
    - end
  region: flash_primary
  size: 0x2000
sram_primary:
  address: 0x20000000
  end_address: 0x20020000
  region: sram_primary
  size: 0x20000

I needed to increase memory allocation for mcuboot, as my mcuboot image increased, so I modified the above static file into below, which is causing hardfault:

app:
  address: 0x10200
  end_address: 0x70000
  region: flash_primary
  size: 0x5fe00
external_flash:
  address: 0x0
  end_address: 0x100000
  region: external_flash
  size: 0x100000
mcuboot:
  address: 0x0
  end_address: 0x10000
  placement:
    before:
    - mcuboot_primary
  region: flash_primary
  size: 0x10000
mcuboot_pad:
  address: 0x10000
  end_address: 0x10200
  placement:
    before:
    - mcuboot_primary_app
  region: flash_primary
  size: 0x200
mcuboot_primary:
  address: 0x10000
  end_address: 0x70000
  orig_span: &id001
  - app
  - mcuboot_pad  
  region: flash_primary
  size: 0x60000
  span: *id001
mcuboot_primary_app:
  address: 0x10200
  end_address: 0x70000
  orig_span: &id002
  - app
  region: flash_primary
  size: 0x5fe00
  span: *id002
mcuboot_secondary:
  address: 0x0
  device: IS25
  end_address: 0x60000
  region: external_flash
  size: 0x60000
settings_storage:
  address: 0x70000
  end_address: 0x80000
  placement:
    before:
    - end
  region: flash_primary
  size: 0x10000
sram_primary:
  address: 0x20000000
  end_address: 0x20020000
  region: sram_primary
  size: 0x20000

Can you suggest now why the modified pm_static.yml file is causing hardfault..?

Thanks,

Ubaid
