Check the value of serverip, nfsserver, and netmask to make sure it conforms to your network.
You can use setenv to change anything that needs to be modified.
(m)
Set boot mode to NFS/TFTP
DM365 EVM:> run set-nfs
DM365 EVM:> run set-tftp
(4) Connect the Ethernet connection on the DM368-ZDVR and make sure the DM368-ZDVR is connected to
the same network as the computer serving as the TFTP and NFS Server.
(
5) From the u-boot prompt, type “boot”
DM365 EVM:> boot
You should see the Z3-DM368-RPS boot the kernel obtained via TFTP, mount a file system using NFS,
and then go straight to the serial menu. Appendix A shows an example of a successful boot. If you are
running into issues, see the “Troubleshooting” section in Appendix C.
