[1] ST7540 B-FSK - Stripped down Power Line Transceiver
Software
- STM SDK 3.5
- STLinux-2.4
- sh4-linux crosstools from STM
Assumptions
- STM reference software SDK 3.5 is built on Host PC as conveyed in STM's documentation given by STM's Field Application Engineer.
- STM reference software SDK 3.5 is configured for "FUDB_GPD201_7540_LINUX DCP_HOST DDR3"
- Can run STM's "Test-Tool" on reference board to test OenGL ES 2.0 and media playback.
- The "sysroot" is located at "<STLinux-2.4 installation path>/STLinux-2.4/devkit/sh4/target"
Qt 4.8.0 EGLNullWS/QWS

- Create folder named "linux-sh4-ST7540-g+" in "qt-everywhere-opensource-src-4.8.0/mkspecs/qws"
- Get following files in "qt-everywhere-opensource-src-4.8.0/mkspecs/qws/linux-sh4-ST7540-g"
h3. Compiling Qt 4.8.0 development environment variables using following commands
cd /path/to/STM/futk_2boxtv_src_c273/stbsp/stdebug/api_test/testapp
source /path/to/STM/futk_2boxtv_src_c273/stbsp/stmake/bin/setenv.sh FUDB_GPD201_7540_LINUX DCP_HOST DDR3
Configure, build and install Qt 4.8.0 as
$ /path/to/qt-everywhere-opensource-src-4.8.0/configure -opensource -confirm-license -verbose -release -shared -no-rpath -system-zlib -system-libjpeg -system-libpng -qt3support -qt-sql-sqlite -xmlpatterns -exceptions -declarative -script -scripttools -webkit -no-javascript-jit -qt-gfx-linuxfb -qt-gfx-transformed -qt-gfx-vnc -qt-gfx-multiscreen -qt-kbd-linuxinput -qt-mouse-linuxinput -make libs -make tools -make examples -make demos -make docs -make translations -platform qws/linux-x86-g''+ —prefix=/path/to/installation/directory/qt-everywhere-opensource-src-4.8.0-qws/ -xplatform qws/linux-sh4-ST7540-g++ -embedded sh4 -little-endian -opengl es2 -plugin-gfx-eglnullws -qt-gfx-directfb -no-dbus
$ make
$ make install
After the build succeeds set following environment variables before building any Qt Apps,
- QTDIR=/path/to/installation/directory/qt-everywhere-opensource-src-4.8.0-qws/
- PATH=/path/to/installation/directory/qt-everywhere-opensource-src-4.8.0-qws/bin/
h2. Qt 5.0 EGLFS/QPA
Only QtBase module is tested.
h3. Compiling Qt 5.0
One need to pass following "device-option"s
- CROSS_COMPILE=<STLinux-2.4 installation path>/STLinux-2.4/devkit/sh4/bin/sh4-linux-
Configure, build and install Qt 5.0 as
$ configure —prefix=/path/to/installation/directory/qt-gitorious-opensource-src-5.0 -release -opensource -confirm-license -shared -verbose -device linux-sh4-stmicro-ST7540-g++ -sysroot <STLinux-2.4 installation path>/STLinux-2.4/devkit/sh4/target -device-option CROSS_COMPILE=<STLinux-2.4 installation path>/STLinux-2.4/devkit/sh4/bin/sh4-linux-
$ make module-qtbase
$ make module-qtbase-install_subtargets
After the build succeeds set following environment variables before building any Qt Apps,
- QTDIR=/path/to/installation/directory/qt-gitorious-opensource-src-5.0/
- PATH=/path/to/installation/directory/qt-gitorious-opensource-src-5.0/bin/
Before executing any Qt applications on target copy "/path/to/installation/directory/qt-gitorious-opensource-src-5.0" from host on target at "/path/to/installation/directory/qt-gitorious-opensource-src-5.0" on target file system
