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]

We started command prompt on an administrator.  I have make sure all the steps before and after step 8 using s132 softdevice version 6.0.  We tried to flash the program via both SES and nrfjprog (like shown in step 8).  We also used difference Bud rate 115200, 57600, 38400, 19200, 14400 and 9600.

Attached are the cmd script file

I got a few tips from a Mesh developer here at Nordic:

"The original issue seems to be an error in the json file. Looks like there is an extra "}" at the end, maybe.

Next, is the customer sure that the com port used is the correct com port?

The SEGGER DFU build had a known issue with the flash_placement.xml file. I would advise the customer to use some of the pre-compiled binaries to test the DFU first."

But I believe you have fixed the first issue, correct? I also believe you are using the correct com port & I believe you have used the pre-compiled binaries & not your own built hex files.

I am not sure these tips will help all too much, but it's worth giving it a shot!

To reply to your suggestions:

• "The original issue seems to be an error in the json file. Looks like there is an extra "}" at the end”.
  Please specify the name of the json file.  If you referred to bootloader_config_default.json which was attached in my last reply, there were two “{“ in the front and two “}” at the end.
• is the customer sure that the com port used is the correct com port?
  There is only one JLink CDC UART Port (COM46) and please see line 120 of cmd script.txt attached in my last reply “target on COM46”. 
  (I want to attach my COM port screen shot image here, but I have no problem to attach images and files from my computer for private ticket. Now I converted to public ticket, I cannot attach images and files from my computer for public ticket.  Can you help me to convert back to private ticket? We can convert back to public ticket until we have a solution, there is no point to post it public without a solution.)  

• The SEGGER DFU build had a known issue with the flash_placement.xml file. I would advise the customer to use some of the pre-compiled binaries to test the DFU first."
  Please see lines 16 to 19 of the attached cmd script.txt in my last reply
  “>nrfutil dfu genpkg --application bin/blinky/blinky_nrf52832_xxAA_s132_6.0.0.hex --company-id 0x00000059 --application-id1 --application-version 2 --key-file private_key.txt --sd-req 0x009D --mesh dfu_test.zip”  where bin/blinky/blinky_nrf52832_xxAA_s132_6.0.0.hex was already pre-compiled.  If this is not the right file, please specify which step and file name that need to be used.

 Please ask your Mesh developer continue working on this until a solution.  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.

A new issue is open in GitHub

[Bjørn Kvaale]

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

[Bjørn Kvaale]

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.

[Bjørn Kvaale]

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!!!
