Hi,

Can you try including both SoftDevice firmware IDs (FWID) for --sd-req when generating the packet?

Also, choose bootloader-version and application-version one higher than the existing bootloader and application respectively.

I keep getting SD Version Failed error when trying to dfu the SD+BOOT+APP.

Here is how I constructed the dfu package

nrfutil pkg generate --softdevice nRF5_SDK_15.0.0_a53641a/components/softdevice/s132/hex/s132_nrf52_6.0.0_softdevice.hex \
                     --bootloader nRF5_SDK_15.0.0_a53641a/examples/dfu/secure_bootloader/pca10040_ble_debug/armgcc/_build/nrf52832_xxaa_s132.hex \
                     --application nRF5_SDK_15.0.0_a53641a/examples/ble_peripheral/ble_app_buttonless_dfu/pca10040/s132/armgcc/_build/nrf52832_xxaa.hex \
                     --key-file private.pem --hw-version 52 --bootloader-version 0xff --application-version 0xff \
                     --sd-req 0x9D --sd-id 0xA8 test.zip

I am using nrfutil 6.1
Going from a SDK14.2 build with SD 132 5.0.0

SDK 15 build with SD 132 6.0.0

I am using a secure boot with own keys but I rebuilt all the sdk pieces to use the correct keys.

Hi,

Yes, this should be possible. Have you tried, and seen any issues?
