Some problem on QEMU of Petalinux

chenzhenyuch

Hi
Linux is booting up ok

I have test my app on QEMU simulation system.

I have got the warning belows when running the CMD:  "petalinux-boot --qemu --kernel".

 

INFO: The image provided is a zImage
WARNING: The QEMU subnet settings is 192.168.10.1/255.255.255.0. It is different from the one configured in PetaLinux /

Another problem is that eth0  have no response and forking to background.  

I have highlighted these two logs. Could you please help to resolve it. 

Thanks very much.

    Hello JFoster,

    I have used the  QEMU system Emulator to run the GDB. However it failed to launch the QEMU.

    I have copied the cmd and error logs as follows:

    1. petalinux-create -t project -s

    /opt/pkg/Avnet-Digilent-ZedBoard-v2015.4-final.bsp
     
    2. petalinux-create -t apps --name myapp --template c
     
    3.petalinux-config -c rootfs
     
    I have selected: apps->myapp & Debugging->build debugable applications. Then save the process.
     
    4.  petalinux-build.  Successfully build the image and kernel.
     
    5,Please see the logs:
