Mesh FDU : bootloader_verify.py failed

[Chaabane]

Hello,

I'm trying to use the mesh DFU on 2 nRF52840 DK by following the quick start guide and it didn't work.

Using the mesh sdk 2.0.1 I made the below batch file as described on the quick guide

When trying to verify the bootloader with bootloader_verify.py it get halt on "resetting device..." (see picture below)

I have used device_page_generator.py and bootloader_verify.phy from mesh sdk v2.2.0 since the original scripts have some bugs.

Timed out waiting for acknowledgement from device.

Failed to upgrade target. Error is: No data received on serial port. Not able to proceed.

Possible causes:
- bootloader, SoftDevice or application on target does not match the requirements 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.

Please, advice me if I'm missing something here ?

Thank you

Hi Chaabane,

Why did you not include the company id or application id in the nrfutil command in step 3? That might be the reason that the dfu is not working.

Kind Regards,

Bjørn

[Chaabane]

Hi Bjorn,

the dfu genpkg don't have the options for company id nor application ID in its options ?

I'm using nrfutil version 0.3.0 that comes with nRFgo Studio as you can see in the screenshot below

I tried also the laster I could found (3.5.1) but still these options are not available in the nrfutil pkg generate command

Does the release version in git (exe file) has the mesh dfu fucntionalities  ?

[Bjørn Kvaale]

You need to download the nrfutil tool shown in the dfu getting started guide. There is a special branch of the file that works for mesh dfu.

[Chaabane]

I have installed nrfutil from the mesh_dfu branch using python setup.py install and I got the following message in the end 

Using c:\python27\lib\site-packages
Finished processing dependencies for nrfutil==3.5.1

so I assume the installation is successful, but when I  check the options in the pkg generate command I don't find company-id and applicaiton-id ?

running nrfutil from source code "ython nordicsemi/__main__.py" gives the same result

Any idea where this is coming from ?

[Bjørn Kvaale]

As you can see from the screenshot below, you should be able to find both the company id & application id:

[Chaabane]

I found the problem, I didn't check the mesh_dfu branch in the first place
Now I have another error when verifying the booloader

bootloader_verify.py 683954026 COM26
Reading UICR.. OK.
Reading Device page.. OK.
Resetting device.. ERROR: Invalid start sequence from bootloader: 81020863
Checkpoints:
Have you flashed the bootloader with nrfjprog?
Does your bootloader have serial communication enabled?

I flashed the bootloader with nrfjprog and when using the bootloader I used have serial comm in it ?

Below is the script i'm using. for sd 6.0.0 the --sd-seq is 0xA9, right ?

Would be helpful if you can take a look at it

Hi,

You forgot to include the private key in step 3 (i.e. --key-file private_key.txt). It is correct to use 0xA9 for the S140 v 6.0.0 softdevice. If you are unsure in the future, you can program the softdevice on a board that has been erased & open up the nrf programmer app in nrf connect for desktop. Then, when you read the memory, you should be able to see the softdevice code in the log.

Another option is to use the command: nrfutil pkg generate --help. There, you should see a list of most of the softdevice codes. You will need to use the regular nrfutil, not the mesh nrfutil.

In step 4, you need to run python before device_page_generator. Otherwise, everything else looks good.

Kind Regards,

Bjørn

Hi Bjorn,

-I don't use any key in the bootlaoder config file, those lines are just there for the final script

-I'm using sdk 2.0.1 which I have used to built my application. when I run the device page script from this sdk It doesn't seem to give me the right output file ? see below:

python device_page_generator.py -d nrf52840_xxAA -sd "s140_6.0.0"

Wrote device page for nrf52840_xxAA with the s140_6.0.0 SoftDevice to bin/device_page_nrf52832_xxAA_s132_5.0.0.hex.

It always outputs a device page for nRF52840 ?

But when using device_page_generator.py from sdk mesh 2.2.0 I get the right output file (at least the name). I compared both scripts and it seems only text formating and small things hat have changed, so I believe it is safe o use it !

In step.8  the application I flash in the Soc is built using Segger. It should work aswell or do you think it's better to built it with CMake ?

[Bjørn Kvaale]

There was an issue with the device page generator python script in mesh sdk v2.0.1. The output name is always based on the nrf52832 device, but the output itself should work fine for the 52840. Yes, you are correct. The device page is safe to use for mesh sdk v2.0.1. It should be fine to build the example using segger instead of cmake.
