I'm trying to do a network boot from uboot of linux, where the boot image is on machines that are nfs mounted. I'm looking for the documentation for the definitions of the environment variables required to perform this task.
The environment variables used by U-Boot are documented in the manual. Please RTFM.
For now, I've got the following definitions, which are close but are not quite there:
...
ethaddr=00:C0:E5:10:00:71 dnsip=137.78.160.9
Not used anywhere.
netmask=255.255.255.0 dnsip2=137.78.160.19
Not used anywhere.
ipaddr=137.78.79.142 gatewayip=137.78.79.1 hostname=ophir serverip=137.78.79.133 bootfile=/afs/jpl/group/claraty/tools/linux/2.4.18/pImage-NEW
Not used anywhere.
All you really need is ethaddr, ipaddr, serverip and eventually netmask and gatewayip (not needed when the server is in the same subnet as the target).
Best regards,
