DFU don't start with nrfutil dfu ble

[Yosi.stx]

Hi, 

I face a problem when trying to perform a DFU firmware update via command line using nrfutil dfu ble. 

I'm using windows 10 and nrfutil.exe version 3.5.0

nrfutil dfu ble -ic NRF52 -pkg app_dfu_package.zip -p COM7 -n "DfuBoot_2018_07_18"

I am using for the PCA10040 EVB as connectivity device

The SoftDevice is: s132_nrf52_5.0.0_softdevice.hex

The SDK is: nRF5_SDK_14.2.0_17b948a

The comport is COM7, since this is the com that I see when using the "nRF Connect" PC application and also with the Device manager.

     

I am sure that I have the connectivity firmware on the connectivity device, since when I try it with option -f it give a feedback: "Board already flashed with connectivity firmware."

When I am using the  "nRF Connect" PC application, the secure DFU process is working, but I want to use the command line DFU since I have the nrfutil python source code and in this way I may try to change some timeouts for our development process.

Thanks,

Yosi.

Hello,

Are you sure that the COM port / the nRF is not used by another application? 

Try to power cycle the board before running the nrfutil command.

I just tested this, with the -f command:

nrfutil dfu ble -ic NRF52 -pkg application\app_dfu_package.zip -p COM20 -f -n "Nordic_Buttonless"

 

I have the following versions of Python and nrfutil:

>python --version
Python 2.7.12

>nrfutil version
nrfutil version 3.5.1

Can you try to update to nrfutil 3.5.1, and python 2.7.12, with the "-f" and try to close anything that may use the nRF connected to COM7.

 

Best regards,

Edvin

Hello,

I have tried a lot of things to make it work, yet with no success.

Regarding your suggestions:

1) The com port is not used by another application. 

2) I did power cycle of the board before running the nrfutil command.

3) My python is 2.7.12 and I have tried several versions of nrfutil (including 3.5.1) on two different PC's .

4) I did several tried with the "-f", always return with: "Board already flashed with connectivity firmware."

Other experiments I have tried:

5) Try with different evaluation boards with NRF51 and NRF52 as the connectivity board.

6) Changing to other version of the nrfutil (3.5.1; 3.4.0; 3.5.0)

7) Try with different PC with windows 7, with new installation of the "pip install nrfutil"

I searched google on: "nrfutil dfu ble error code 13"  and I have found that it is repeated issue for many other users, yet there was no good answer for this problem. 

Maybe it has to do with the fact that my target board is in DFU mode from the bootloader itself and not from "buttonless application"?

Could it be that there is an issue with the "pc_ble_driver_py" ?

Is there any importance to the order of the parameter given to "nrfutil dfu ble ..." command?

for example:

nrfutil dfu ble -ic NRF52 -n "DfuBoot_2018_08_16" -p COM45 -pkg Fake_app.zip
nrfutil dfu ble -ic NRF52 -p COM45 -pkg Fake_app.zip -n "DfuBoot_2018_08_16"

p.s. in the other PC the "Jlink CDC Uart port" was changed to COM45.

Also, your version of nrfutil is probably fine.  But if you want to try building it from source, you can do the following:

mkdir nrfutil
cd nrfutil
git clone https://github.com/NordicSemiconductor/pc-nrfutil.git .
pip2 install -r requirements.txt
pip2 install pyinstaller
pyinstaller nrfutil.spec

This assumes you have Python 2.x and git installed. After this, it will produce an nrfutil.exe file in the 'dist' folder.  You can move it wherever you want.  Just make sure that directory is in your PATH variable before the Python path listing (otherwise it will run the version of nrfutil you installed via pip).  Again, I doubt the nrfutil is the problem, but it's worth a shot.

Also, it would help if you explained a bit more about the setup.  So, you have your nRF connectivity device connected to the COM port with the connectivity firmware flashed to it.  What about the target device?  Is it also a PCA10040?  Does it already have a DFU bootloader flashed to it?  Is it a custom bootloader or did you flash a sample from the SDK to it?  Are you signing the ZIP package with the correct key?  Some more details would be helpful.

[Yosi.stx]

The target device is "our" board (not PCA10040) compiled with our Public key while the ZIP package is appropriate one created with the correct private key. I am sure about it since the whole DFU process is working perfectly fine when I am using exactly the same combination of HW, FW and ZIP package but running the DFU from the nrf Connect application.

I can't use the sample from the SDK since our board has different pin layout from the PCA10040.

I put Device Monitor Studio on the UART communication between the PC and the connectivity device, and got this info, maybe it can help if an expert will look on it?

[Yosi.stx]

I even tried to change to connectivity FW to:

connectivity_1.0.1_115k2_with_s132_3.0.hex

according to this recommendation: here

It also did not help, I still get the following feedback:

C:\Python27\Lib\site-packages\nordicsemi>__main__.py dfu ble -ic NRF52 -p COM7 -n "DfuBoot_2018_08_16" -pkg app_128FF.zip -f
Board already flashed with connectivity firmware.

Hello,

I see that you have tried many different solutions, from the list.

1: Are you sure you have added the nrfutil tool to your environment path on the computer?

2: You do have two devices, right? One for the connectivity board, and one for your target board (the DFU target)?

3: Is the connectivity board an nRF development kit, or is this also a custom board?

 

Regarding the different versions of the different tools. You can stick to the latest version of nrfutil, v 3.5.1 and Python 2.7.12 (which is what I use). I also tend to use "-f", since it ensures that the correct version of pc-ble-driver is flashed to the board (which depends on what version of nrfutil you use).

 

Best regards,

Edvin

Hello Edvin.

Thank you for the answer.

1) usually, for create zip packages, I worked with the nrfutil.exe that is in "c:\util\" folder which is on my PC environment path. And from there I began trying to do the DFU with nrfutil.

Only after I become desperate I started to use  __main__.py from:

"C:\Python27\Lib\site-packages\nordicsemi>" which obviously is not in the environment path. have to say that in both cases the result was: Error code: 13

2+3) the connectivity board:  PCA10040;  

target board: Our board (based on nRF52832), 

The combination of those boards can perform DFU when using the nrf Connect.

[Edvin]

Hello,

Do you use the debug bootloader projects? I don't see that it should cause any problems with opening the com-port, so it is a shot in the dark, but still worth a shot.

 

I have a  zip-folder which I used to test the nrfutil DFU operation once.

 

can you unzip it and test it? All you should have to do is to open flash_bootloader.bat in notepad, and change all the references to --snr 682654319 with --snr <SeggerID of your DFU chip>, and change COM20 with the corresponding COM port of your connectivity DK (Keep the brackets ").

Then you can just run the flash_bootloader.bat in CMD, and it should flash the bootloader, and do the DFU transfer using nrfutil.

DFU_test.zip

 

You probably need 2x DK to test this. If that doesn't work. What Segger JLink version do you have on your computer?

 

Best regards,

Edvin

[Yosi.stx]

Hello,

I do have 2 EVBs, but one is PCA10040 (nrf52) and the other is PCA10028 (nrf51).

For trying your files, can I use the PCA10028 as the connectivity board and the PCA10040 as the target board?

My Segger JLink version is "JLink_V620i".

The Segger JLink version is OK, since both of the EVBs work fine as connectivity boards when I work with the "nRF Connect v2.3.0" running on my PC (see attached figures).

PCA10040  as connectivity board:

PCA10028 as connectivity board:

In both cases I can perform successful secure DFU with many ZIP packages that I have created.

The only problem is with the nrfutil when used as DFU controller.

[Edvin]

You need to change the bottom nrfutil line in the .bat-file.

Attached the modified .bat file. Make sure to replace the original file (It has to have the same path as the one included in the zip folder)

nrfutil dfu ble -pkg dfu_packages\app_dfu_package2.zip -ic NRF51 -p "COM20" -n "Nordic_Buttonless" -f

 

Try it, and let me know whether it works or not.

 

EDIT:

You still need to remember to change COM20 to whatever COM port that the nRF51DK is connected to.

Also change the --snr <serial_number> with the serial number of your dfu target DK.

 

Best regards,

Edvin

Hello,

Thank you for your help and for the files.

I have changed all the required changes in the batch file. 

I have downloaded the SoftDevice, buttonless, bootloader and settings to my nrf52 target board and used the nrf51 as the controller board.

I used the command prompt window in administrator mode and it failed as usual.

Here are the results:

C:\Projects\Dalton\DFU_test>nrfutil dfu ble -pkg dfu_packages\app_dfu_package2.zip -ic NRF51 -p "COM8" -n "Nordic_Buttonless" -f

I really start to believe that this failure has to do with the drivers that connect Python to Windows.

Could anyone suggest any clue in that direction?

As usual the same combination of boards and packages worked fine with my PC nRF connect program.

Here are some screenshots:

[Yosi.stx]

At last the issue has been solved.

In the bottom line: the problem is due to the fact the nRF connect and nfrutil do not use the same connectivity FW.

When ever I used the EVB with nrfutil, even with the parameter "-f ", it found a connectivity FW, but is was the connectivity FW that suites the nRF connect. Only after I start the session of nrfutil from something else (not connectivity FW), the "-f " parameter took place and the appropriate connectivity FW for nrfutil was downloaded to the EVB and afterwards nrfutil worked as expected.

Thanks for all the support.
