1. Connect a keyboard via USB 2.0 (15), a monitor via HDMI (31) and a network cable (9).

2. Provide power to the main power plug in GOOSE board (8).

   • Connector: Floppy drive power cable on a standard PC power supply
   • Voltage: 12V DC
   • To use a standard PC power supply without mainboard, connect the ATX pin PC_ON (power on) to ground (see https://en.wikipedia.org/wiki/ATX)

3. After boot, a prompt is shown on the connected monitor:

   (goose-arm-rootfs-build)root@goose:~# _
   

4. If you want to modify the keyboard layout type dpkg-reconfigure keyboard-configuration and select the desired layout. The default layout is German.

5. Network configuration:

   • Get the MAC address with ifconfig.
   • Add the MAC address and hostname to your DNS server configuration (not on the SBC).
   • Set the desired hostname in the /etc/hostname file. The default hostname is goose. Available editors are vim and nano
   • Reboot the SBC: reboot

6. Now, you can connect from another PC to the SBC via SSH: ssh root@HOSTNAME. The default password is root. It can be changed with the command passwd.

7. Check if the FPGA PCIe device is detected. If not reboot.

   (goose-arm-rootfs-build)root@goose:~# lspci
   00:00.0 PCI bridge: Device 16c3:abcd (rev 01)
   01:00.0 Non-VGA unclassified device: Xilinx Corporation Device 7024
   

8. Check if the symlink to the registers is created. If not call initctl start fhgpcie

   (goose-arm-rootfs-build)root@goose:~# ls -l /dev | grep fhgpcie
   lrwxrwxrwx 1 root dialout       43 Jan  1  1970 fhgpcie -> /sys/bus/pci/devices/0000:01:00.0/resource0
   

9. Informations about the FPGA design can be shown with print_hw_version

   (goose-arm-rootfs-build)root@goose:~# print_hw_version
   timestamp: 2015-11-29 14:55:04
   git revision: FACCB604
   proj id: 46EB
   jenkins build: 337
   

10. Check if the lock LED on the front-end board (V400) is on. If not press the reset button on the front-end board (S400).

11. Enable/disable antenna power (4.5V DC, max. 80mA). It is disabled by default. Overcurrent is indicated by the LED on the front-end board (V603). An external antenna can be connected to the MMCX connector on the front-end board (X602).

    antenna_power_on
    antenna_power_off
    

12. Check the gain of the front-end with read_sample_rec. If it shows no Gaussian distribution, press the reset button on the front-end board (S400). With the -s option the signal can be selected.

    (goose-arm-rootfs-build)root@goose:~# read_sample_rec -s E1
    sh: 1: /usr/bin/lsof: not found

13. Test the acquisition with tst_fft_acq. GPS 1-32, SBAS 120, 124, 126, Galileo 1-50.

    (goose-arm-rootfs-build)root@goose:~# tst_fft_acq 
    sh: 1: /usr/bin/lsof: not found

14. The receiver program is called ogre_console. CPU core 1 is reserved for GNSS applications. To bind a process to this core, use taskset.

    taskset -c 1 ogre_console --gps-l1
    

15. The default data output is STDOUT, but can be changes with the option "--ogrp-output".

16. For more options use ogre_console --help.

17. The output format of the receiver is OGRP. See https://github.com/Fraunhofer-IIS/ogrp.

18. Serial connection

19. The SBC has one CAN connector (X1006):
