The hardware has a pre-installed environment based on OpenWrt and the hardware platform "Freeescale i.MX23/28". OpenWrt there is accessible by SSH "root:root" and allows to install packages in format IPKG.

To build a package of OpenSCADA of IPKG there was used a ready SDK of the platform "Freeescale i.MX23/28" for OpenWrt version "Chaos Calmer (15.05.1)", BuildRoot rules of OpenSCADA and the generic description of OpenWrt.

OpenSCADA was built with the modules:

• DB: {SQLite, DBF};
• Transport: {Sockets, Serial}, SSL;
• Protocol: {SelfSystem, UserProtocol, HTTP};
• DAQ: {JavaLikeCalc, LogicLev, BlockCalc, DAQGate, ModBus, DCON}, System, OPC_UA;
• Archive: {FSArch, DBArch};
• UI: WebCfg, WebCfgD, WebUser;
• Special: {FLibSYS}, SystemTests, FLibMath, FLibComplex1.

OpenSCADA also was built with the internationalization support by libraries "libiconv" and "libintl" but the initial environment of OpenWrt doesn't support the internationalization in whole!

To install the OpenSCADA package to the device we also needed for some extra depend packages: libstdcpp, libintl-full, fftw3, sqlite3. Then we must download all the packages to the device by SSH, for example to folder "/root" and next to connect remotely to the console interface by SSH and call here:

opkg install /root/libstdcpp_4.8-linaro-1_mxs.ipk
opkg install /root/libintl-full_0.19.6-2_mxs.ipk
opkg install /root/fftw3_3.3.4-1_mxs.ipk
opkg install /root/sqlite3-cli_3081101-1_mxs.ipk
opkg install /root/openscada_0.9+r2517-1_mxs.ipk
