@sam131208 This error is happening due to a missing PR in zephyr's mcuboot: mcu-tools/mcuboot#1362
This should be already synced but it was not. I asked maintainers to take a look. This is same root cause for this: #45349.
So I will close this as duplicated, ok?
Would you try using upstream mcuboot instead?
