dfu MESH NRF_ERROR_INVALID_DATA when changing application

Chaabane

Hello,

I have prepared an nRF52840 with DFU example (dfu_nrf52840_xxAA_s140_6_0_0).

When making the DFU package for the blinky example (bin/blinky/blinky_nrf52840_xxAA_s140_6.0.0.hex) the DFU process works correctly

When I prepare again the board and make a DFU package with my application, the DFU process failed and it says NRF_ERROR_INVALID_DATA

Failed to upgrade target. Error is: Device returned status code ERROR_INVALID_DATA (135) on a DFU data packet.

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.
Closing serial port...

This error is returned by nrf_mesh_dfu_rx() in serial_handler_openmesh_rx(). 

Do I have to make any changes to my application in ordre to be able to flash it using mesh DFU ?

I have read the related posts to this problem but so far, nothing really works

    Update:

    I integrated the DFU mesh into my application.

    Making the dfu pakcage with blinky example (bin/blinky/blinky_nrf52840_xxAA_s140_6.0.0.hex), everything works correctly.

    When making the pakage with my application (new version), I get the following

    1- Without defining -i

    nrfutil --verbose dfu serial -pkg dfu_test.zip  -p COM26 -b 115200 -fc --mesh

    It always crashes

Failed to upgrade target. Error is: Crashed on start packet

    I beleive the board is busy erasing the memory that's why nrfutil gets no response from the board as showed in the log above, I might be wrong but if it's the case, how can this be fixed ?

    2 - defining -i to 500

    nrfutil --verbose dfu serial -pkg dfu_test.zip -i 500  -p COM26 -b 115200 -fc --mesh

    If doesn't always work, sometimes I get 0x86 (SERIAL_STATUS_ERROR_BUSY) error but after few tries it work but the process take about 2 hours!

    3-defining -i  to 1000 : process always work (didn't continue to the end)

    what might cause this issue ? Have you tested this using a large application (hex file is 685 Kb) ?

    If you are using the dual banked version, will the application fit ? (edited)

    I assume that you will need to store the entire application via DFU and also allow the currently running application to run so space needs will be at the maximum.

    Can you verify the space available.
