[U-Boot-Users] Ramdisk over NFS

[U-Boot-Users] Ramdisk over NFS

[Clint Thomas]

Hey guys,

I am looking to load the Ramdisk image over NFS onto my development
board, instead of using the NFS mount AS the root file system. The
reason for this is that our ethernet is not yet working from within
linux, so it will not hold onto the NFS mount. I want it to load the
linux image over NFS, then load the Ramdisk image into memory so it
works on the dev board. Is this possible? Thank you for your prompt
response

It is possible to load files via NFS from U-Boot. The configuration
parameter CFG_CMD_NFS has to be set. Take a look into the sources
in common/cmd_net.c .

Why can't you use TFTP to load the Linux kernel and ramdisk, like
most other people do?

As I already wrote to you in private mail:  yes,  this  is  possible.
Just use the "nfsboot" command in U-boot (or TFTP).

*BUT*: please read the netiquette, and don't send the same message to
mailing list(s) plus individuals. This is wasting our time, and  thus
kind of impolite.
