Booting the ast2700fc machine
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AST2700 features four Cortex-A35 primary processors and two Cortex-M4 coprocessors.
**ast2700-evb** machine focuses on emulating the four Cortex-A35 primary processors,
**ast2700fc** machine extends **ast2700-evb** by adding support for the two Cortex-M4 coprocessors.
Steps to boot the AST2700fc machine:
1. Ensure you have the following AST2700A1 binaries available in a directory
* u-boot-nodtb.bin
* u-boot.dtb
* bl31.bin
* optee/tee-raw.bin
* image-bmc
* zephyr-aspeed-ssp.elf (for SSP firmware, CPU 5)
* zephyr-aspeed-tsp.elf (for TSP firmware, CPU 6)
2. Execute the following command to start ``ast2700fc`` machine:
.. code-block:: bash
IMGDIR=ast2700-default
UBOOT_SIZE=$(stat --format=%s -L ${IMGDIR}/u-boot-nodtb.bin)
$ qemu-system-aarch64 -M ast2700fc \
-device loader,force-raw=on,addr=0x400000000,file=${IMGDIR}/u-boot-nodtb.bin \
-device loader,force-raw=on,addr=$((0x400000000 + ${UBOOT_SIZE})),file=${IMGDIR}/u-boot.dtb \
-device loader,force-raw=on,addr=0x430000000,file=${IMGDIR}/bl31.bin \
-device loader,force-raw=on,addr=0x430080000,file=${IMGDIR}/optee/tee-raw.bin \
-device loader,cpu-num=0,addr=0x430000000 \

After launching QEMU, serial devices will be automatically redirected.
Example output:
.. code-block:: bash
char device redirected to /dev/pts/55 (label serial0)
char device redirected to /dev/pts/56 (label serial1)
char device redirected to /dev/pts/57 (label serial2)
- serial0: Console for the four Cortex-A35 primary processors.
- serial1 and serial2: Consoles for the two Cortex-M4 coprocessors.
Use ``tio`` or another terminal emulator to connect to the consoles:
.. code-block:: bash
$ tio /dev/pts/55
$ tio /dev/pts/56
$ tio /dev/pts/57
