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

Thank you very much for the provided information. I really appreciate the degree of detailing in your post, so one can reproduce all steps.

Unfortunately, the Rasperry Pi support was broken in release 14.05. We got aware of that fact at the end of July by a post on this list. Now, we nightly test the Rasperry Pi platform, and things should work properly. Please, switch to Genode's release 14.08. I'm afraid you'll have to do some of the prepare steps again, but the build system will warn you if this is the case. Also, please assure to do a 'make cleanall' in your build directory after the upgrade, before you proceed again.

Regards Stefan

PS: I'm sorry, I've missed your previous mails about building for Rasperry Pi, otherwise I would have warned you earlier
