Hi Bruce, I noticed that you've committed the changes for qemuarma9 KMACHINE configuration to the linux-yocto kernel.http://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto-3.8/tree/meta/cfg/kernel-cache/bsp?h=meta I adapted the qemuarm.conf configuration and booted it up, but nothing shows up in the QEMU window, I just get a black screen. Has qemu with the qemuarma9 configuration been successfully built and tested before?
It has been, but not with a machine definition that is part of oe-core or Yocto. It was contributed as the output from some cortexA9 testing, and I've been carrying the kernel parts ever since.
This is how my qemuarm.conf looks like, locally at the moment: #@TYPE: Machine #@NAME: qemuarmhf #@DESCRIPTION: Machine configuration for QEMU ARM Cortex A9 hard float. # Specify the default tune. DEFAULTTUNE = "armv7a-neon" require conf/machine/include/qemu.inc require conf/machine/include/tune-cortexa9.inc # Specify the machine name used by the kernel. KMACHINE_qemuarm = "qemuarma9"
This is a default, so you don't need to set it.
# Specify the kernel image type. KERNEL_IMAGETYPE = "zImage"
I recall booting it with a uImage, but maybe my memory is failing.
# Specify the serial console parameters. SERIAL_CONSOLE = "115200 ttyAMA0"
All of the above looks reasonably sane, but it's more about how you launch qemu than the kernel build that is probably resulting in your issues. What machine subtype did you use ? Bruce
