Aspeed family boards (``*-bmc``, ``ast2500-evb``, ``ast2600-evb``)
|
|
==================================================================
|
|
|
|
The QEMU Aspeed machines model BMCs of various OpenPOWER systems and
|
|
Aspeed evaluation boards. They are based on different releases of the
|
|
Aspeed SoC : the AST2400 integrating an ARM926EJ-S CPU (400MHz), the
|
|
AST2500 with an ARM1176JZS CPU (800MHz) and more recently the AST2600
|
|
with dual cores ARM Cortex A7 CPUs (1.2GHz).
|
|
|
|
The SoC comes with RAM, Gigabit ethernet, USB, SD/MMC, USB, SPI, I2C,
|
|
etc.
|
|
|
|
AST2400 SoC based machines :
|
|
|

|
|
- ``romulus-bmc`` OpenPOWER Romulus POWER9 BMC
|
|
- ``witherspoon-bmc`` OpenPOWER Witherspoon POWER9 BMC
|
|
- ``sonorapass-bmc`` OCP SonoraPass BMC
|
|
- ``swift-bmc`` OpenPOWER Swift BMC POWER9
|
|
|
|
AST2600 SoC based machines :

|
|
|
- ``ast2600-evb`` Aspeed AST2600 Evaluation board (Cortex A7)

Boot options
|
|
------------
|
|
|
|
The Aspeed machines can be started using the -kernel option to load a
|
|
Linux kernel or from a firmware image which can be downloaded from the
|
|
OpenPOWER jenkins :
|
|
|
|
https://openpower.xyz/
|
|
|
|
The image should be attached as an MTD drive. Run :
|
|
|
|
.. code-block:: bash
|
|
|
|
$ qemu-system-arm -M romulus-bmc -nic user \
|
|
-drive file=flash-romulus,format=raw,if=mtd -nographic
|
|
|
|
Options specific to Aspeed machines are :
|
|
|
|
* ``execute-in-place`` which emulates the boot from the CE0 flash
|
|
device by using the FMC controller to load the instructions, and
|
|
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.
|
|
|
|
* ``spi-model`` to change the SPI Flash model.
|
|
|
|
For instance, to start the ``ast2500-evb`` machine with a different
|
|
FMC chip and a bigger (64M) SPI chip, use :
|
|
|
|
.. code-block:: bash
|
|
|
|
-M ast2500-evb,fmc-model=mx25l25635e,spi-model=mx66u51235f
