This is the batch file that genrates the upgrade packege.

nrfutil pkg generate --hw-version 52 --sd-req 0xB6 --application-version 2 --application nRF5_SDK_17.1.0_ddde560/examples/ble_peripheral/ble_app_buttonless_dfu/pca10056/s140/arm5_no_packs/_build/nrf52840_xxaa.hex --softdevice nRF5_SDK_17.1.0_ddde560/components/softdevice/s140/hex/s140_nrf52_7.2.0_softdevice.hex --bootloader nRF5_SDK_17.1.0_ddde560/examples/dfu/secure_bootloader/pca10056_s140_ble_debug/arm5_no_packs/_build/nrf52840_xxaa_s140.hex --bootloader-version 2 --sd-id 0x0100 --key-file priv.pem dfu_15.3-17.1.zip

Can you tripple check? Looking at the code, I am not able to see any other explanation for this. The error is printed from this snippet in the bootloader:

        else if (p_init->hw_version != NRF_DFU_HW_VERSION)
        {
            NRF_LOG_WARNING("Faulty HW version.");
            ret_val = EXT_ERR( NRF_DFU_EXT_ERROR_HW_VERSION_FAILURE);
        }

Are you sure the bootloader that is running was built with NRF_DFU_HW_VERSION set to 52? Did you program it now, or could it be that it does not run the bootloader you think it does?

And regarding the DFU image, could it have been a mixup? Can you check the zip file using "nrfutil pkg display <file>"?

[shark]

1.NRF_DFU_HW_VERSION default value is 52,unchanged.

2.nrfutil pkg display as follows.

Hm, that is most peculiar. Perhaps you can modify the bootloader and log a bit more. First of all, start with components/libraries/bootloader/dfu/nrf_dfu_ver_validation.c and the section I posted in my previous reply. Then print both p_init->hw_version and NRF_DFU_HW_VERSION separately to see which value they have there. Clearly they are not the same in this check, so it would be good to know which of them have a different value, and what that is. Then we can continue from there.
