SDK 15 and Mesh 2.0 Generate a DFU file with nrfutil - ValueError

[iotlight]

We used nRF5_SDK_15.0.0_a53641a and nrf5_SDK_for_Mesh_v2.0.0_src.

We are following DFU quick start guide http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v0.10.0%2Findex.html

For nRF52:

mesh-sdk$ nrfutil dfu genpkg --application bin/blinky/blinky_nrf52832_xxAA_s132_5.0.0.hex \

--company-id 0x00000089 \

--application-id 1 \

--application-version 2 \

--key-file private_key.txt \

--sd-req 0x009D \

--mesh dfu_test.zip

We used "--company-id 0x00000089 \" to match Step 2 public key:

{

"bootloader_config": {

"bootloader_id": 1,

"bootloader_version": 1,

"company_id": 89,

"application_id": 1,

"application_version": 1,

"public_key": "ed09a58df6db5cd15b8637304f31d31f4042492ed7c7e4839fbe903f260a2ba1a855e92b72885825481ad56282bcf549ad7455ec46f000f0f62d97eeec883ba6"

}

}

The hex we used is C:\Nordic\nRF5_SDK_15.0.0_a53641a\mesh_sdk\bin\blinky\blinky_nrf52832_xxAA_s132_5.0.0.hexblinky_nrf52832_xxAA_s132_5.0.0.hex

We got ValueError, please see attached screen shot. 

Please advise.  Thanks

[iotlight]

Sorry, please forget above error.  Today, we started from step 1 of the DFU quick start guide

Now we got TypeError.  I also attached bootloader_config_default.json and the file tree of SDK 15 and Mesh.  Please advise.  Thanks.

Sorry for the delayed response. From your command line input in the comment, it seems that you did not generate the private_key.txt file. My guess is that you did do this step, as generating the public key did not lead to an error. Just want to make sure that it is not a small error like this that has lead to this issue.

[iotlight]

Hi Bjorn,

We started everything from scratch following the DFU quick start guide from step 1 to step 4, then we got stuck

    }
}

We got the exact same "TypeError" as before.  Please advise.  Thanks.

[Bjørn Kvaale]

I have tested the DFU quick start guide using both Mesh SDK v2.0.0 & v2.0.1 & I receive the exact same TypeError as you do. I will mention this to the developers of nrfutil & see if they have any suggestions.

Update:

There was an issue with the python device_page_generator.py file. Should work if you download this file & copy it into the tools/dfu folder. I do not get any errors with step 4, but have not had time yet to test the rest. Could you please let me know if everything else works fine? If it does not, I will test a bit later.

Thanks Bjorn.  Yes, Step 4 works now.  We continued following the DFU quick start guide, but since Step 8 stated that "Building the mesh stack. If you have built them with Segger Embedded Studio, you can flash the DFU example directly from the IDE, as described in the build-guide, and move on to step 9."

I think we got step 8 done, but not sure how to verify it so we just skipped step 8 and move to step 9.  Now we are up to Step 10.  Please see the attached CMD Scripts that 

Failed to upgrade target. Error is: Serial port could not be opened on COM48. Re

Possible causes:
- bootloader, SoftDevice or application on target does not match the requirement
s in the DFU package.
- baud rate or flow control is not the same as in the target bootloader.
- target is not in DFU mode. If using the SDK examples, press Button 4 and RESET
 and release both to enter DFU mode.
