i have spent such a long time to find a possible solution to debug with linux in eclipse + qemu , but without result .
i find some many tools with gcc :
arm-linux-gcc arm-none-linux-gnueabi-gcc arm-xilinx-linux-gnueabi-gcc
i find some many possible ways to start with qemu :
qemu-system-i386 qemu-system-arm qemu-system-x86_64 qemu-system-arm -s -S qemu-system-x86_64 -s -S -kernel bzImage qemu-system-x86_64 -s -S -kernel bzImage -append "root=/dev/sda" -hda busybox.img -monitor stdio
we can find out many ways to make a ramdisk or root file system
