is there a nrfutil compatibility matrix for SDK versions?

[Allen]

Hello,

Is there any documentation available that specifies what version of nrfutil is required to create DFU packages which are compatible with a SDK and/or soft device version?

Thanks

Amanda,

I have read the nrfutil manual. It does not tell you how to deal with backward compatibility issues.

For instance, nrfutil 6.1.0 provides several boot/image verification options. These are not available with the old nrfutil. What are the proper settings if you are creating a DFU package for SDK15, s132, soft device 5.0?

Thanks

Hi Allen, 

Not sure I understand the issue correctly or not. I can use this command to generate the DFU package for app + s132 v5.0.0 with the nrfutil 6.1.0.

nrfutil pkg generate --application ble_app_buttonless_dfu_pca10040_s132.hex --application-version-string "1.0.0" --hw-version 52 --sd-req 0x9D --sd-id 0x9D --softdevice s132_nrf52_5.0.0_softdevice.hex --key-file private.pem FW.zip

Does it help you?

Amanda,

I can generate DFU packages. However they don't appear to be compatible with s132, SDK14, soft device 5.0. They will not download. However if I create the DFU package using the older utility, it works.

Hi Allen, 

I used SDK14/bootloader_secure_ble, s132_nrf52_5.0.0_softdevice, ble_app_buttonless_dfu and nrfutil version 6.1.0, but couldn't reporduce. 

There are the commands (and file 253662.zip) I used:

>nrfutil version
nrfutil version 6.1.0
>mergehex -m nrf52832_bootloader_secure_ble_s132.hex s132_nrf52_5.0.0_softdevice.hex -o mergedBootloaderSoftdevice.hex
>nrfjprog --program mergedBootloaderSoftdevice.hex --chiperase -r

>nrfutil pkg generate --application nrf52832_ble_app_buttonless_dfu.hex --application-version-string "1.0.0" --hw-version 52 --sd-req 0x9D --sd-id 0x9D --softdevice s132_nrf52_5.0.0_softdevice.hex --key-file private.pem FW.zip
