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!

Did you  apply 

"nrfjprog --reset" on step 9?

[Bjørn Kvaale]

Hi Shubhangi, could you please open a new devzone case regarding this issue? Kind Regards, Bjorn

[shubhangir]

Hi, yes, unfortunately still see the issue. I will open another case to follow up. thank you.

[shubhangir]

Opened a new case at https://devzone.nordicsemi.com/f/nordic-q-a/35341/issue-doing-dfu-over-ble-mesh-setup-1-target-board-nrf52840-dev-kit-s140-mesh-2-0-1-nrf-sdk-15-0-0

I followed the DFU quick start guide using 2 development kits, where one (682630616) is interfaced over the COM port, which is the one we have been using to check out from Step 1 to Step 10.  Now I am using the other development kits (682686733) receives the DFU from the first device (682630616) over the mesh.  According to the DFU quick start guide, I specified which device to use in which context, add the -s 682686733 option for each call to the nrfjprog command.  Therefore, we started to communicate with 682686733 starting Step 5 to Step 9 as below:

Step 5 Erase all chip memory (including UICR) on all devices
nrfjprog --eraseall -s 682686733

Step 6 Flash the SoftDevice on all devices
nrfjprog --program bin/softdevice/s132_nrf52_6.0.0_softdevice.hex --chiperase -s 682686733

Step 7 Flash the serial bootloader on all devices
nrfjprog --program bin/bootloader/gccarmemb/mesh_bootloader_serial_gccarmemb_nrf52832_xxAA.hex -s 682686733

Step 8 Flash the first application on all devices
nrfjprog --program examples\dfu\build\dfu_nrf52832_xxAA_s132_6.0.0_Release\dfu_nrf52832_xxAA_s132_6.0.0.hex -s 682686733

Step 9 Flash the device page on all devices
nrfjprog --program tools/dfu/bin/device_page_nrf52832_xxAA_s132_6.0.0.hex -s 682686733

nrfjprog --reset -s 682686733

Every Step, I got an error:
ERROR: There is no debugger connected to the PC with the given serial number.

Please see below attached screen shoot.

 

Do we need to connect the other development kit 682686733 to the PC?  How can we do it over the mesh or over the air?

According to the DFU quick start guide, I also downloaded the mesh_dfu branch as shown at below screen shoot, but I don't know how to use it. 

Please advise.  Thanks.

iotlight Like I mentioned in the comment above, I would use nrfjprog --reset -s without the Segger ID. That way, if you have multiple dev kits attached to your pc, you will get a popup where you can select the correct ID.

Another tip: make a script to automate all of the steps. I should have done this from the beginning too, but did not.

In general, it is a good idea to connect all of the dev kits to your computer via usb. That way, you can program & power the DKs via USB. You will need to attach both DKs to the computer via USB. That is the reason you are getting the error.

You will need to program both kits via USB with the softdevice, bootloader & application before you can do a DFU over the mesh network.

There is documentation which shows how to install the nrfutil mesh branch. What happens when you enter the command "nrfutil version" in a command prompt?
