not simply from RAM. This takes a little longer.
* ``fmc-model`` to change the FMC Flash model. FW needs support for
the chip model to boot.
* ``fmc-model`` to change the default FMC Flash model. FW needs
support for the chip model to boot.
* ``spi-model`` to change the SPI Flash model.
* ``spi-model`` to change the default SPI Flash model.
* ``bmc-console`` to change the default console device. Most of the
machines use the ``UART5`` device for a boot console, which is
mapped on ``/dev/ttyS4`` under Linux, but it is not always the
case.
For instance, to start the ``ast2500-evb`` machine with a different
FMC chip and a bigger (64M) SPI chip, use :
To use other flash models, for instance a different FMC chip and a
bigger (64M) SPI for the ``ast2500-evb`` machine, run :
.. code-block:: bash
-M ast2500-evb,fmc-model=mx25l25635e,spi-model=mx66u51235f
When more flexibility is needed to define the flash devices, to use
different flash models or define all flash devices (up to 8), the
``-nodefaults`` QEMU option can be used to avoid creating the default
flash devices.
Flash devices should then be created from the command line and attached
to a block device :
.. code-block:: bash
$ qemu-system-arm -M ast2600-evb \
-blockdev node-name=fmc0,driver=file,filename=/path/to/fmc0.img \
-device mx66u51235f,bus=ssi.0,cs=0x0,drive=fmc0 \
-blockdev node-name=fmc1,driver=file,filename=/path/to/fmc1.img \
-device mx66u51235f,bus=ssi.0,cs=0x1,drive=fmc1 \
-blockdev node-name=spi1,driver=file,filename=/path/to/spi1.img \
-device mx66u51235f,cs=0x0,bus=ssi.1,drive=spi1 \
-nographic -nodefaults
In that case, the machine boots fetching instructions from the FMC0
device. It is slower to start but closer to what HW does. Using the
machine option ``execute-in-place`` has a similar effect.
To change the boot console and use device ``UART3`` (``/dev/ttyS2``
under Linux), use :
