Configuring and performing DFU over Mesh

[Kunny]

I have a question about how to perform DFU over Mesh.

I'm using nRF52840 device.

Following the steps at the URL below (Configuring and performing DFU over Mesh), I'm trying Mesh DFU which is a combination of Mesh5.0 s140_7.2.0.

 

[URL]

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v4.0.0%2Fmd_doc_libraries_dfu_dfu_quick_start.html

 

But, I could not generate a DFU file on Step 1(Generate a DFU archive with nrfutil).

At that time, I got some errors.

Could you please tell me why I could not generate the DFU file ?

I explain details of the problem at the follows.

 

[the problem]

When I tried to generate a DFU file with "blinky_nrf52840_xxAA_s140_7.2.0.hex"

in the located of "nrf5_SDK_for_Mesh_v5.0.0_src\bin\blinky",

I got the following error:

 

"pc-nrfutil\nordicsemi\intelhex\__init__.py", line 342, in _tobinarray_really raise ValueError("tobinarray: wrong value for size")

ValueError: tobinarray: wrong value for size

 

In order to analyze the above problem,

I tried to perform which is a combination of Mesh4.2,following the steps at the URL.

And then, it worked fine.

So, I compared "blinky_nrf52840_xxAA_s140_7.2.0.hex" with "blinky_nrf52840_xxAA_s140_7.0.1.hex"

that has used as the update application of Mesh 4.2.

The file structure and the mapped address look very different.

I guess that "blinky_nrf52840_xxAA_s140_7.2.0.hex" has some problem.

That's why I could not generate the DFU file.

Please tell me your opinion.

 

Thanks in advance.

Hi Kunny, 

Please describe to me what exactly you are trying to do ? 
Are you trying to do DFU over Mesh as described here?
Or are you trying to do DFU over BLE (non mesh) as described here ? 

Please include all  the scripts you used to generate the .zip package and to perform DFU update.

Hi Hung Bui,

I'm trying to do DFU over Mesh as described here.

Please see "mesh_dfu_command_20210407.txt" in the attached file.

You can find several commands that I have executed for mesh DFU.

Please let me know if the procedure is wrong.

DevZone_0407.zip

Is it possible to operate mesh DFU with the DFU file that is generated using "device_page_nrf52840_xxAA_s140_7.2.0.hex" ?

Thanks in advance,

Kunny

Hi Kunny, 

Thanks for the detailed info. What you did seems to be good. I am not sure what could be wrong, but I suspect that there was not enough time for the DUT to erase flash pages to prepare for new image. 
Could you please try to test with the blinky firmware as showed in the documentation ? The blinky firmware is much smaller than the image you are trying to update so it would requires much less time. 

Please try to test updating the blinky without any private or public key generated (open DFU) so we know if it's the issue with the keys or not. 

If the blinky image works ,but not your image, you can try to increase SEND_START_DFU_WAIT_TIME and SEND_DATA_PACKET_WAIT_TIME , please have a look at a similar case here: https://devzone.nordicsemi.com/f/nordic-q-a/39777/dfu-mesh-nrf_error_invalid_data-when-changing-application

Hi Hung Bui,

Thank you for your co-operation.

> Could you please try to test with the blinky firmware as showed in the documentation ?

I already did the above test.

Please see the top of this topic. 

The result is as follows:

###

I could performed Mesh DFU which is a combination of Mesh5.0 and s140_7.2.0 

using sample hex file > "1832.blinky_pca10056.hex".

###

> If the blinky image works ,but not your image, you can try to increase 

> SEND_START_DFU_WAIT_TIME and SEND_DATA_PACKET_WAIT_TIME.

I tried the following combinations.

But because of the error that described in the top of this topic,

Serial communication doesn't work for all tests.

[test1]

　　SEND_START_DFU_WAIT_TIME = 2.0 (default)

　　SEND_DATA_PACKET_WAIT_TIME = 1.0 (modified)

[test2]

　　SEND_START_DFU_WAIT_TIME = 2.0 (default)

　　SEND_DATA_PACKET_WAIT_TIME = 2.0 (modified)

[test3]

　　SEND_START_DFU_WAIT_TIME = 2.0 (default)

　　SEND_DATA_PACKET_WAIT_TIME = 3.0 (modified)

[test4]

　　SEND_START_DFU_WAIT_TIME = 5.0 (modified)

　　SEND_DATA_PACKET_WAIT_TIME = 3.0 (modified)

Do you have any idea to solve this issue?

Thanks in advance,

Kunny

Hi Kunny, 
I'm sorry that I forgot about that you have successfully tested with blinky firmware. 

I tried to test with your files and it worked fine for me. 

You can find the log here, i used the same .zip file that you sent.

 I attached here the files I used, including the nrfutil.exe file that I used, could you please try the same scripts (my script.txt) and test on your machine ? 
Comparing the 2 logs from you and from me, it seems that the first packet send after "waiting for 4.4 seconds" was stuck in your case.

I suspect that 4.4 s might not be enough in your case (because of your chip might be slow for example) 

Could you try to edit send_init_packet function inside dfu_transport_mesh.py to add extra sleeping time ? For example instead of *1.5 , you can try *3 :

Please try to also test on other DK board.
