Run in QEMU
-----------
Download and compile Linaro version of qemu which contains ``n900`` qemu
machine. Source code is available in qemu-linaro git repository and the
last working version is at commit 8f8d8e0796efe1a6f34cdd83fb798f3c41217ec1.
Use following commands to compile ``qemu-system-arm`` binary with ``n900``
qemu machine support:
.. code-block:: bash
git clone https://git.linaro.org/qemu/qemu-linaro.git
cd qemu-linaro
git checkout 8f8d8e0796efe1a6f34cdd83fb798f3c41217ec1
./configure --enable-system --target-list=arm-softmmu --disable-werror
make -j4
cd ..
ln -s qemu-linaro/arm-softmmu/qemu-system-arm .
Using ``n900`` qemu machine requires proprietary Nokia qemu ``qflasher`` tool
(in reality it is just generator of qemu MTD images) with first stage images
(``xloader-qemu.bin`` and ``secondary-qemu.bin``), similar what is required
on the real HW. License of flasher and images allows non-commercial
redistribution and it is available at maemo.org website:
.. code-block:: bash
wget -c http://repository.maemo.org/qemu-n900/qemu-n900.tar.gz
tar -xf qemu-n900.tar.gz
To generate qemu bootable MTD image ``mtd.img`` from U-Boot binary
``u-boot.bin`` and unpacked first stage images, run following command:
.. code-block:: bash
./qflasher -v -x xloader-qemu.bin -s secondary-qemu.bin -k u-boot.bin -m rx51 -o mtd.img
Instead of ``u-boot.bin`` binary it is possible to also used combined
U-Boot + kernel binary ``combined.bin``.
Finally, to boot ``mtd.img`` with graphics display and keyboard with optional
serial console on current terminal, run:
.. code-block:: bash
./qemu-system-arm -M n900 -mtdblock mtd.img -serial /dev/tty
Additionally it is possible to emulate also eMMC and uSD card by appending
qemu ``-sd`` arguments:
.. code-block:: bash
./qemu-system-arm -M n900 -mtdblock mtd.img -sd emmc.img -sd sd.img -serial /dev/tty
For more examples, look into the ``test/nokia_rx51_test.sh`` CI testing script.
