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

I believe it might be best if you add a new issue at this github link for nrfutil. They should be quite quick in debugging the issue for you. The mesh developer I have talked to is quite busy & does not have the time currently to debug this issue. If you have found a fix to this problem, could you please update this thread with the solution?

Regarding not being able to upload pictures, we have done a test & found out that it is possible to attach images & files in this thread. Which browser are you using? We tested with Google Chrome & that worked very well.

Great! I will let the team know to take a look at the case ASAP.

I have tried the whole dfu quick start guide again & received this error while trying to do the DFU:

Will talk to the nrfutil developer, ask him to try & get back to you soon.

Finally found the answer! Tried the dfu quick start guide using mesh v2.0.0. Used two nrf52832 dev kits & softdevice v5.0.0. I uploaded the blinky hex file located in the bin/blinky/blinky_nrf52832_xxAA_s132_5.0.0.hex. In step 8, I built the segger embedded studio project for the dfu example using the 5.0.0 softdevice (since only the emproject for the 6.0.0 softdevice is available in the mesh sdk). Here is the link to building the mesh stack using cmake (see the subsection "Generating SEGGER Embedded Studio project files).

To make it simpler, I have uploaded the zipped mesh sdk that I used. 

nrf5_SDK_for_Mesh_v2.0.0_src.zip

The changes you will need to make relate to step 8 in the quick start guide. You will need to make changes to the generated SES project using the v5.0.0 softdevice in the flash_placement.xml file located in examples/dfu/.

 

The fix for this is relatively simple: In examples/dfu/flash_placement.xml, change line 32 from

  <MemorySegment name="RAM" start="$(RAM_PH_START)" size="$(RAM_PH_SIZE)">

to

  <MemorySegment name="RAM" start="$(RAM_PH_START)" size="$(RAM_SIZE)">

 

After this, follow all of the steps & the dfu should complete without any issues. Hope that helps & sorry for the long time it took in getting this to work!!!
