swupdate provides a reliable way to update the software on an embedded system.
Note that swupdates has a reworked Kbuild/Kconfig system. It has now support
for the 'option' and 'env' symbols as well for the 'savedefconfig' target.
This makes dependency handling much easier. We're now able to pass which
dependencies are available through the environment, as suggested by Arnout
Vandecappelle [1].
In previous version of this patch we had a configuration setting where all
package dependencies except Lua were selected by default. This has changed with
v7 as we are now able to pass dependencies to the swupdate build system through
the environment. For useful operation swupdate requires a parser which depends
by default on libconfig, but can be replaced by a json-c or Lua parser.
To provide a reasonable firmware update system we enable the embedded webserver
based on mongoose (also see notes about mongoose below), a parser as stated
above and a handler for raw NAND or NOR flash.
The user can modify this configuration by selecting the appropriate dependencies
before running `make swupdate-menuconfig`. The help text contains information
about which packages may be of interest for the user.
The embedded web server requires a website for proper operation. We install the
included website by default, however the user may choose to install a custom
website on the post-build scripts.
Note, swupdate includes some old versions of mongoose and lsqlite3:
- mongoose is version 3.8 from year 2013
- lsqlite3 is version 0.8 from year 2011
Currently, swupdate does not provide a way to replace these with external
packages.
This patch is based on a WIP version submitted by Romain Naour, commented by
Arnout Vandecappelle [2].

+ swupdate provides a reliable way to update the software on an
+ embedded system.
+
+ swupdate is highly configurable to fit the targets requirements and
+ to minimize the footprint. The provided default configuration file
+ BR2_PACKAGE_SWUPDATE_CONFIG will enable swupdate with an embedded
+ webserver, a parser and a handler for raw NAND or NOR flash.
+
+ The default configuration file builds a reasonable firmware update
+ system with minimal external dependencies in my mind. If you like to
+ use your own modified configuration, you have to select the
+ necessary packages manually:
+
+ * Select BR2_PACKAGE_LUA_5_2 if you want to have Lua support.
+ * Select BR2_LIBCURL if you want to use the download feature.
+ * Select BR2_PACKAGE_OPENSSL is you want to add encryptions support
+ to the webserver.
+ * Select BR2_PACKAGE_MTD if you want to use swupdate with UBI
+ partitions.
+ * Select BR2_PACKAGE_ZLIB if you want to deal with zip compressed
+ archives.
