[U-Boot-Users] How to use tftp to book kernel image and mount remote root fs

[Steven Woody]

Dear Denk,

Q1:

Both 5.9.5.1 ( http://www.denx.de/wiki/view/DULG/UBootCmdGroupDownload#Section_5.9.5.1.
) and 5.9.5.6 (
http://www.denx.de/wiki/view/DULG/UBootCmdGroupDownload#Section_5.9.5.6.
) talk about booting image via network, but there are only few lines
of description about these commands.  I don't know which one I should
use, tftpboot or bootp? And, for each one, what's the requirement on
server side?  I've done works described in 4.6, 4.7, 4.8 to setup the
server, but I don't sure which one ( tftp, dhcp, nfs ) will really be
used.


Q2:

in 9.6.3 ( Root File System on a cramfs File System ), the manual
taught how to make a root filesystem image (cramfs), but in the
installation ISO, i dont find necessary files rootfs.tar.gz and
devices.tar.gz mentioned in the instructions.  Where should I get
them?  On the other hand, after installed the eldk, I've already got a
root filesystem in /installation/path/arm, so i think it will be very
good building a root filesystem image from this directory, but in the
manual, I dont find instructios telling me how.


Thank you very much.

across the current.
