** Description changed: - Please add a build-dep on libfdt-dev, which will add flat device tree - support to qemu. This will let users pass the '-dtb' command line - option, allowing us to specify a device tree file. Though it is - supposedly possible to pass a dtb file to the instance by appending it - to the zImage, I've been unable to get this to work (even with - CONFIG_ARM_APPENDED_DTB=y). The -dtb method is more straightforward and - I've been able to boot a highbank target with it (and the patch - referenced in #1030588): + [Impact] - ubuntu@server-1343577662-az-3-region-a-geo-1:~$ sudo qemu-system-arm -nographic -M highbank -m 4089 -kernel ~/vmlinuz-3.2.0-2000-highbank -append console=ttyAMA0 -dtb ~/highbank.dtb + [Fix] + + [Test Case] + + [Regression Potential] + + [Original Report] + Please add a build-dep on libfdt-dev, which will add flat device tree support to qemu.
