Re: [EXTERNAL] Re: running pc686 samples on QEMU on RTEMS 5.1?
Hi Karel,
Your suggested options fixed it! Our next release should be compatible with
RTEMS 5.1.
The documentation is great too.. As a long time RTEMS user, I often fail to
check the docs first!
Thanks,
Alan

^ this looks fine, you can also try -append "--video=off
--console=/dev/com1" -- which would basically mean what you used to use
in 4.x with those BSP compile time options above. E.g. console on COM1.
But to have it working, you need to IIRC! remove disabling of VGA.

running pc686 samples on QEMU on RTEMS 5.1?
NASA’s Core Flight System open source bundle has support for the RTEMS 4.11
pc686 BSP.
RTEMS is built with the following options:
../rtems/configure --target=i386-rtems4.11 \
--enable-rtemsbsp=pc686 \
--prefix=${HOME}/rtems-4.11 \
--enable-networking \
--enable-cxx \
--disable-posix \
--disable-deprecated \
BSP_ENABLE_VGA=0 \
CLOCK_DRIVER_USE_TSC=1 \
USE_COM1_AS_CONSOLE=1 \
BSP_PRESS_KEY_FOR_RESET=0 \
BSP_RESET_BOARD_AT_EXIT=1
And the code (or samples such as ticker) are run with the following QEMU
command:
qemu-system-i386 -m 128 \
-kernel core-cpu1.exe \
-drive file=fat:rw:${INSTALL_DIR}/cpu1,format=raw \
-nographic \
-no-reboot
(Where core-cpu1.exe is the cross compiled application. I can also run
ticker.exe and other samples with this command )
When I build the pc686 BSP with the same examples and try running on QEMU with
the same options, QEMU returns immediately.
Is there a different set of options I should use for the pc686 BSP on RTEMS 5.1?
Thanks,
Alan
