i'm perusing the openwrt QEMU page here: http://wiki.openwrt.org/doc/howto/qemu
so i thought i'd test a couple of the architectures with images downloaded from the 14.07-rc3 directory. all this is being done on a 64-bit fedora rawhide system with the appropriate qemu-system-* packages installed. so here's where i'm getting the images from: https://downloads.openwrt.org/barrier_breaker/14.07-rc3/... first, MIPS, where i tried to boot just the kernel image: $ qemu-system-mipsel -kernel openwrt-malta-le-vmlinux.elf -nographic -m 256 [ 0.000000] Linux version 3.10.49 (bb@builder1) (gcc version 4.8.3 (OpenWrt/Linaro GCC 4.8-2014.04 r41989) ) #1 SMP Fri Aug 8 02:50:38 CEST 2014 [ 0.000000] Config serial console: console=ttyS0,38400n8r [ 0.000000] bootconsole [early0] enabled [ 0.000000] CPU revision is: 00019300 (MIPS 24Kc) [ 0.000000] FPU revision is: 00739300 ... snip ...
