I have the right one. Following the documentation, I was able to boot a kernel with qemu for the linux-xlnx and qemu-xilinx. But this kernel is outdated regarding the upstream one, so I tried to boot a 3.11-rc4 kernel without success, I did the following: I used the default config file from linux-xlnx for the upstream kernel. I compiled the kernel with: make -j 5 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- UIMAGE_LOADADDR=0x8000 uImage I generated the dtb with: make -j 5 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- dtbs For qemu, I started qemu with: ./arm-softmmu/qemu-system-arm -M arm-generic-fdt -nographic -smp 2 -machine linux=on -serial mon:stdio -dtb zynq-zed.dtb -kernel kernel/zImage -initrd filesystem/ramdisk.img I tried with the dtb available for the upstream kernel: zynq-zc706.dtb, zynq-zc702.dtb and zynq-zed.dtb Did I miss something ?
