Appendix B: Troubleshooting

Problem: Web interface does not come up

-Is the Ethernet cable plugged in to the Z3-DM816X-VI-RPS solidly (do you see the link light)?
-Does the Z3-DM816X-VI-RPS IP address and the PC IP address have the same first 2 values (or, if

netmask is set to 255.255.255.0, the same first 3 values)?

-Do the Z3-DM816X-VI-RPS and the PC running VLC have the same netmask? (Default value is

255.255.0.0)

-You can check the netmask of the PC by typing ifconfig in Linux.

-Are all firewalls on the network turned off?

-Try connecting the PC directly to the board without any routers etc.

-Can the Linux PC and target board see each other on the network?

-Try pinging the Z3-DM816X-VI-RPS IP address from the Linux PC.

-Try pinging the Linux PC from the Z3-DM816X-VI-RPS.

Problem: Do not see video in VLC (UDP)

-Does the IP address set in “Dest Address” equal the IP address of the PC running VLC?

-Does the port number in “Dest Port” equal the value entered in the URL for VLC?

-Does the video coming out of the source match the resolution in the encoder settings?

-Is the PC fast enough for 1080p decode on VLC?

-Does the PC have enough DDR to handle 1080p decode on VLC?

-Is VLC version 1.1x or later?

Problem: Do not see video in VLC (RTP)

-Is “Dest Port” set to 5004?

Problem: Get an error message while building

-Were all modules for Linux installed? (See 3.1 Preparing the Linux Environment, on page 9).

Problem: TFTP does not work

-(Please see the items in “Web interface does not come up”)

-Does the file “uImage” exist in z3-netra-rdk/images?

-Is the link to images properly set up (see step (3) on page 27)?
-If you take serverargs in

/etc/xinetd.d/tftp

and combine that with tftp_root in u-boot, does it point

to the images directory?

-Did you start the TFTP server?
-Is there another PC on the network conflicting with the IP address of the TFTP server?
