Has anybody sucessfully enabled SMP (software management protocol) over SHELL using a UART ?

[Nick74]

I'm fairly new to Zephyr and initially I'm hoping someone can point me to an example where SMP over UART can be used to update a firmware image slot.  Google seems to have a lot of information relating to KConfig options that no longer seem to exist with regards to using the SMP protocol via Zephyr shell - and browsing through KConfig I cant quite seem to find something that works or a document that explains things nicely.   The typical Google response would be 'do this' (below) but it seems the KConfig options are renamed or missing

# Enable the Zephyr shell subsystem

CONFIG_SHELL=y

CONFIG_SHELL_BACKEND_SERIAL=y

# Enable the Simple Management Protocol (SMP)

CONFIG_MCUMGR=y

CONFIG_MCUMGR_TRANSPORT_SHELL=y

# You may also need general SMP support

CONFIG_MCUMGR_SMP=y

# Enable specific command groups as needed (examples)

CONFIG_MCUMGR_CMD_IMG_MGMT=y    # Image management (for DFU)

CONFIG_MCUMGR_CMD_OS_MGMT=y     # OS management commands (e.g., reset, tasks)

CONFIG_MCUMGR_CMD_FS_MGMT=y     # File system management

Hi,

Yes, I can get compile errors. But I would like to backtrack a bit to your previous post, it looks like you may be off on a slightly wrong path. Normally, MCUboot is built by sysbuild when you build your application and I am having problems understanding your project layout and how you configure things. I suggest you do as demonstrated in the SMP server sample. You should also have a look at Enabling a bootloader chain using sysbuild. Lastly, as bootloader and DFU can be complex, I suggest having a look at lesson 9 in nRF Connect SDK Intermediate.

If you still have problems, please share the project along with build logs and description so that I can get a better understanding of what you are doing.
