What is the trick to get the networking active with the Linaro QEMU
emulating a beaglexm running Linaro Alpha 3? ifconfig -a only shows the
loopback interface.
I am creating the boot image with:
#!/bin/sh

QEMU is being run with the following options:
#!/bin/sh
DISK=beagle_sd.img
qemu-system-arm \
-nographic \
-M beaglexm \
-m 512 \
-net nic \

-sd ${DISK}
The head of my git tree for the Linaro
QEMU (git://git.linaro.org/qemu/qemu-linaro.git) is:
commit c67ccff50fd53723302c47a233f3daec2807cf0d
Author: Peter Maydell <peter.mayd...@linaro.org>
Date: Fri Mar 4 11:56:20 2011 +0000
Changelog.LINARO: add note about prlimit64 emulation
Add entry to Changelog.LINARO about prlimit64 (a fix added
to the 2011.03-0 release at the last minute).
ifconfig -a only shows the following:
