segmentation logic in mcumngr image management

[Omid]

Hi there,

I am trying to find the logic implemented in a source code which performs the following steps:


1) reading from a binary file that represents the firmware image that needs to be sent over to the destination for the firmware update.
2) this should include segmentation as the firmware images are large which cannot be sent in one go.
3) I cannot find where and how this segmentation happens.

Any help or suggestion is appreciated.

Hi,

I'll leave this post open to the Devzone forum to chime in, but I assume you've spent some time here already? https://github.com/nrfconnect/sdk-mcumgr This is the downstream fork that we keep in NCS from MCUmgr and should contain what you're asking for. You can also always investigate the upstream https://github.com/zephyrproject-rtos/mcumgr or investigate if other users have spent time on this in the Zephyr discord discussion forums.

Kind regards,
Andreas
