smp_svr

This sample application implements a simple SMP server with the following transports: * Shell * Bluetooth

smp_svr enables support for the following command groups: * fs_mgmt * img_mgmt * log_mgmt * os_mgmt

Mynewt

The Mynewt port of smp_svr is a regular Mynewt app. The below example uses the nRF52dk as the BSP, so you may need to adjust accordingly if you are using different hardware.

Create a Mynewt project and upload the Apache mynewt boot loader to your board as described here: http://mynewt.apache.org/latest/os/tutorials/nRF52/
Add the mcumgr repo to your project.yml file:

repository.mynewt-mcumgr:
    type: git
    vers: 0-latest
    url: 'git@github.com:apache/mynewt-mcumgr.git'

Create a target that ties the smp_svr app to your BSP of choice (nRF52dk in this example):

$ newt target create smp_svr-nrf52dk
$ newt target set smp_svr-nrf52dk app=@mynewt-mcumgr/samples/smp_svr/apache \
                                  bsp=@apache-mynewt-core/hw/bsp/nrf52dk    \
                                  build_profile=debug

Build, upload, and run the application on your board:

$ newt run smp_svr-nrf52dk

Zephyr

The Zephyr port of smp_svr is configured to run on an nRF52 MCU. The application should build and run for other platforms without modification, but the file system management commands will not work. To enable file system management for a different platform, adjust the CONFIG_FS_NFFS_FLASH_DEV_NAME setting in prj.conf accordingly.

In addition, the MCUboot boot loader (https://github.com/runtimeco/mcuboot) is required for img_mgmt to function properly.

The smp_svr app logs reboots to a flash circular buffer (FCB) backed log. The flash map for the nRF52 only allocates flash for either the NFFS file system or the FCB, but not both. By default, this application uses the FCB log, not the file system. You can enable the NFFS file system and disable the FCB as follows-

In zephyr/prj.conf, uncomment the FILE_SYSTEM settings and comment out the FLASH and FCB settings:

    # Enable the NFFS file system.
    CONFIG_FILE_SYSTEM=y
    CONFIG_FILE_SYSTEM_NFFS=y

     # Enable the flash circular buffer (FCB) for the reboot log.
    #CONFIG_FLASH_PAGE_LAYOUT=y
    #CONFIG_FLASH_MAP=y
    #CONFIG_FCB=y

Link in the NFFS library by uncommenting the NFFS line in zephyr/CMakeLists.txt:

    zephyr_link_libraries(
        MCUMGR
        NFFS
    )

Building

The Zephyr port of smp_svr can be built using the usual procedure:

$ cd samples/smp_svr/zephyr
$ mkdir build && cd build
$ cmake -DBOARD=<board> ..
$ make
