what exactly is netconsole
Hi,
A recent post mentions that U-Boot now has netconsole features, at least on the ocotea PPC440 board. What type of functionality does this provide? I did find, on the web, that netconsole is UDP based at is typically used as a networked console for kernel debugging.
Does this imply a "one-way" output connection only or does it allow a remote connection into the target - similar to telnet.
Our project requires remote network access to U-Boot because the deployed the system will not include a serial port.

netconsole pipes stdin or stdout (or both) to a network device

Pretty much...

The other end is netcat (see u-boot/doc/README.NetConsole for the appropriate script)
http://netcat.sourceforge.net/
It sounds like this is what you need for your project.

In general it is a good idea to read the available documentation. Ideally, you do this BEFORE posting to the mailing list.
May I bother you to have a look at the doc/README.NetConsole file?

U-Boot has bidirectional communication over the network, i. e. both
stdin and stdout can be redirected (indepoendently!) to the
netconsole device.

Our work is currently based on the 1.1.1 release. Any plans for an upcoming release that would include this document, along with netconsole?
In the mean time, I'll try to grab the README from the CVS tree.
