Appendix B: Troubleshooting
Problem: Get an error message while building
-Were all modules for Linux installed? (See
3.1 Preparing the Linux Environment
, on page 8).
Problem: TFTP does not work
-Is the Ethernet cable plugged in to the Z3-DM368-ZDVR board solidly (do you see the link light)?
-Does the Z3-DM368-ZDVR 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-DM368-ZDVR and the PC with the TFTP server 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-DM368-ZDVR IP address from the Linux PC.
-Try pinging the Linux PC from the Z3-DM368-ZDVR.
-Does the file “uImage” exist in z3-dm368/images?
-Is the link to images properly set up (see step 2e)?
-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?
Problem: NFS does not work
-(Please see the first 5 items in “TFTP does not work”)
-Is the link to filesys properly set up (see step 2e)?
-Does the IP address in the line added in /etc/exports match the IP address set in nfsserver in u-boot?
-Does the value of nfs_root in u-boot point to z3-dm368/filesys/fs?
-Did you start the NFS server?
-If you modified the exports file, did you remember to restart the NFS server after that?
When contacting Z3 Support for additional support, please capture and include a log file with the
