DFU distributor for Network core firmware

[a.da]

Hello.

I am developing using nRF5340DK and nRF Connect SDK v2.8.0.
I want to create a DFU distributor that updates both Application core firmware and Network core firmware.
But I think this sample program is not supported Network core firmware.
I checked Application core firmware update with this sample.
samples/bluetooth/mesh/mesh_dfu/distributor

I have some questions.

• Are there any existing tickets related to this? I have not been found.
• I think the following changes are needed. What else is needed?
  • main.c
    • Add a "struct bt_mesh_blob_io_flash" instance for Network core firmware.
  • dfu_dist.c
    • Add a "struct bt_mesh_blob_io_flash" instance pointer for Network core firmware.
    • Switch a response pointer from "fw_core_type".
      dfd_srv_recv(), dfd_srv_send().
  • dfu_target.c
    
    • Add "struct bt_mesh_blob_io_flash" instance pointer for Network core firmware.
    • Switch a response pointer from "fw_core_type".
      dfu_start(), dfu_recover().
    • Add a check logic for Network core firmware.
      dfu_meta_check().
  • mesh_dfu_metadata.py
    
    • Generate a metadata for Network core firmware.

Thanks for reading.

Hi a.da,

The DFU over Mesh solution unfortunately isn't fully supported on the nRF5340 yet, as of nRF Connect SDK v2.8.0.

May I ask what stage your project is at, and if there is any particular reason you want the nRF5340? Perhaps the nRF52840 or the new nRF54L15 can suit your need as well.
