This page instructs in debugging N900 device in using a USB connection.

Note: For instructions in debugging Qt applications running on a remote MeeGo device, see Debugging in Qt Creator.

Debugging N900 device

To debug your application on your N900 device using a USB connection:

1. Set up an SSH connection to your N900 device:
   1. Start X Terminal and log in as root:

      sudo -i

   2. Open the interfaces file. You can do this, for example, by running vim /etc/network/interfaces.
   3. Add the following text into the file and save the file:

      /opt/meego/qemu-arm/bin/qemu-system-arm -M n900 -mtdblock meego-handset-armv7l-qemu-1.0.90.3.20100921.1.img -sd sd-empty -sd meego-handset-armv7l-qemu-1.0.90.3.20100921.1-mmcblk0p.raw -serial stdio -clock unix -redir tcp:6666:10.0.2.15:22

   4. Connect your N900 device to your computer with the USB cable:
2. To install gdbserver on device, set up usb networking:
   1. Start X Terminal on your N900 device and add the default gateway:

      route add default gw 192.168.2.14 usb0

   2. On your host computer, copy resolv.conf from /etc directory to the corresponding directory on your N900 device:

      scp /etc/resolv.conf root@192.168.2.15:/etc/

   3. Install gdb server:

      zypper in gdb-gdbserver

3. Configure build settings for your application by selecting Projects mode > Build Settings > MeeGo sysroot Debug.
4. Configure run settings for your application by selecting your device configuration.
5. Switch to Edit or Debug mode.
6. Add breakpoints to your code by right-clicking and selecting Set Breakpoint.
7. Click Start Debugging.
