Hello Support Team.

I am encountering an issue where the settings_storage partition located in external flash is being erased during an MCUboot image upgrade.

Environment
SDK:               nRF Connect SDK v3.1.1
Toolchain:      nRF Connect SDK Toolchain v3.1.1

• Zephyr + MCUboot

• External SPI NOR flash (4 MB total)

• Secondary slot located in external flash

• settings_storage also located in external flash

• Image upgrade performed via MCUmgr (test + swap)

Partition Layout (external_flash)

0x00000000 - 0x000EFFFF  mcuboot_secondary
0x000F0000 - 0x0012FFFF  mcuboot_secondary_1 (previous configuration)
0x00130000 - 0x00133FFF  empty
0x00134000 - 0x00137FFF  settings_storage (16 KB)
0x00138000 - 0x003FFFFF  remaining external flash

Observed Behavior

During image swap, the log shows multiple sector erase operations in the external flash region:

spi_nor: SPI ERASE opcode=0x20 size=4096 addr=0x0010D000
spi_nor: SPI ERASE opcode=0x20 size=4096 addr=0x00134000
spi_nor: SPI ERASE opcode=0x20 size=4096 addr=0x00135000
...

The addresses 0x00134000 and above correspond to the settings_storage partition.

After the upgrade completes, all stored settings are lost, indicating that the partition was erased as part of the swap operation.

Expected Behavior

settings_storage should remain intact during firmware upgrades and not be erased as part of the MCUboot swap process.

Questions

1. Is MCUboot expected to erase the entire external flash region during swap when secondary slot resides there?

2. Is this caused by incorrect partition boundaries or overlap with swap/scratch areas?

3. Should settings_storage be moved outside of the secondary slot region (e.g., to the end of flash)?

4. Is there a recommended partition layout to protect settings in external flash when using MCUboot swap?

I would appreciate guidance on the correct configuration to ensure settings_storage is not affected by firmware updates.

Thank you for your assistance.

Best regards, Serhii.
