Help testing arora,qt5 and sdl examples on RaspberryPI

[Reinier Millo Sánchez]

Hi
I'm testing some examples of Genode on RaspberryPI, but i got some 
troubles. I'm trying to test arora, qt5 and sdl examples. I'm using 
Genode 14.05. I have configured the following ports:

    ./tool/ports/prepare_port arora
    ./tool/ports/prepare_port dde-linux
    ./tool/ports/prepare_port libc
    ./tool/ports/prepare_port stdcxx
    ./tool/ports/prepare_port mesa
    ./tool/ports/prepare_port zlib
    ./tool/ports/prepare_port icu
    ./tool/ports/prepare_port jpeg
    ./tool/ports/prepare_port libpng
    ./tool/ports/prepare_port openssl
    ./tool/ports/prepare_port freetype
    ./tool/ports/prepare_port lwip
    ./tool/ports/prepare_port qoost
    ./tool/ports/prepare_port bintuils
    ./tool/ports/prepare_port sdl
    make prepare PKG=qt5 (on libports)

On etc/build.conf have activated the following repositories:

    REPOSITORIES += $(GENODE_DIR)/repos/base-hw
    REPOSITORIES += $(GENODE_DIR)/repos/base
    REPOSITORIES += $(GENODE_DIR)/repos/os
    REPOSITORIES += $(GENODE_DIR)/repos/demo
    REPOSITORIES += $(GENODE_DIR)/repos/libports
    REPOSITORIES += $(GENODE_DIR)/repos/ports
    REPOSITORIES += $(GENODE_DIR)/repos/dde_linux
    REPOSITORIES += $(GENODE_DIR)/repos/gems

To compile the example have used the following command lines:

    make run/arora
    make run/qt5
    make run/sdl

During the compilation process of the examples, get this line, but 
finally the elf image is generated:

    /usr/local/genode-gcc/bin/genode-arm-ld: BFD (GNU Binutils) 2.22
    assertion fail ../../../../contrib/binutils-2.22/bfd/elf32-arm.c:12049

To generate the img file from the elf image have used:

    /usr/local/genode-gcc/bin/genode-arm-objcopy -Obinary
    var/run/arora/image.elf genode_arora.img
    /usr/local/genode-gcc/bin/genode-arm-objcopy -Obinary
    var/run/qt5/image.elf genode_qt5.img
    /usr/local/genode-gcc/bin/genode-arm-objcopy -Obinary
    var/run/sdl/image.elf genode_sdl.img

To test this img on the RPI have created the config.txt file with:

    kernel=<file>.img
    kernel_address=0x00800000

To test the examples i'm using a RPI model B and a version of QEMU with 
functional support for RPI:

    https://github.com/Torlus/qemu/

When test the elf images with QEMU get the output on serial console, but 
this version of QEMU seems like don't support framebuffer emulation. 
After that have tried to run examples on the real PI but only get the 
coloured screen.
I have compiled and tested on th RPI the Demo and Hello examples.
If somebody can help me?
Best regards
