[OE-core] [oe-core] QEMU with ARM Cortex A9 with hard float configuration - Kernel panic

[Elvis Dowson]

Hi,
       I have modified the default qemuarm.conf file, to switch it over to using ARM Cortex A9, with hard float, vfp and neon support, by applying the following patch (which basically includes the tune-cortexa9.inc file).

diff --git a/meta/conf/machine/qemuarm.conf b/meta/conf/machine/qemuarm.conf
index d07084b..2ec57d8 100644

 KERNEL_IMAGETYPE = "zImage"

I find that the kernel panics upon boot. 

Is it possible to have a QEMU build with support for hard float? 

I need this, so that I can bootstrap a Ubuntu build from scratch, using a QEMU arm hard float machine, using a oe-core generated QEMU and toolchain. I don't want to use the default armel or armhf emulator and toolchain provided by debian, and want to build my own version of the emulator and toolchain, specifically optimized for a particular target machine.

I've attached a screenshot below.



Best regards,

Elvis Dowson
