Can you explain this in a bit more detail.
if, for whatever reason, the nfsboot env var has been modified/deleted, one can't restore it via the command line because it doesn't fit in the buffer. Currently command-line typing stops 2 chars short of its full definition, i.e,. at the 2nd 'd' in 'fdtaddr':
=> setenv nfsboot 'setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netdev:off console=$consoledev,$baudrate $othbootargs;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr - $ fdtadd
Instead of extending buffer sizes just to be able to enter some incomrephensible looooong variable setting you should try and figure out how to structure environment settings, so they become easier to understand and to manage to the end user.
The manual holds some pretty edicative examples.
Best regards,
