DFU Error INVALID_PARAMETER after uploading of all packets via DFU.

[rico]

I am trying to upload an image via BLE DFU, tested on mobile phone and Desktop (Windows) But I receive the following error after all packages have been sent to the device. Without signature required from the bootloader side everything works. With #define NRF_DFU_REQUIRE_SIGNED_APP_UPDATE 1, the following error occurs.

One might assume the package was generated with the wrong private key, but if I do that, the DFU aborts before the first packet is sent. The same is true if the wrong application version is set in the firmware package. So what else can be done wrong?

.local/bin/nrfutil pkg generate --hw-version 52 --sd-req 0x0100 --application-version 9999 --application /mnt/c/git/nrf52833/Output/Debug/Exe/firmware_256ms.hex --key-file private.pem app_dfu_package.zip

Hello,

It looks like the error might be occuring the in the post-validate step in nrf_dfu_validation.c:postvalidate():postvalidate_app(). Maybe you have enabled the 'NRF_BL_APP_SIGNATURE_CHECK_REQUIRED' config setting in your sdk_config.h header? In that case, you will need to include the signature of the app in the dfu pacakage.

E.g.

.local/bin/nrfutil pkg generate --hw-version 52 --sd-req 0x0100 --application-version 9999  --app-boot-validation VALIDATE_ECDSA_P256_SHA256 --application /mnt/c/git/nrf52833/Output/Debug/Exe/firmware_256ms.hex --key-file private.pem app_dfu_package.zip

Thanks, that is the solution.

Just to be clear, if we want the bootloader only to accept signed firmware packages, what option has to be enabled. As far as i understand the bootloader now validates the firmware at boot-time. That's fine. But what if we do not want to validate at boot, or after flashing, whenever it happens and only reject non-signed packages. Which option is that?

Or are there only 2 options:

1. Enable NRF_BL_APP_SIGNATURE_CHECK_REQUIRED and validate firmware sometime after transferring
2. Disable NRF_BL_APP_SIGNATURE_CHECK_REQUIRED and there is no need for signed packages at all

[Vidar Berg]

NRF_DFU_REQUIRE_SIGNED_APP_UPDATE is the setting you should enable to make the bootloader only accept signed FW updates. The NRF_BL_APP_SIGNATURE_CHECK_REQUIRED setting is to require signature Boot validation of the app like you said.
