Can you check my pm_static.yml file and see if anything wrong there..?

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

I will request my colleague to help me with this question as to why increasing the mcuboot image size causes the hardfault. Please bare with us for some time while he gets time to respond.
