PXE boot / NFS
 
Hi,

I'm crawling slowly to success on booting my linux system (Montavista 4.0.1) to the target hardware.

I've managed now to get a ip address on the target via dhcp server on the hostside: 192.168.0.5.

I have managed to load the kernel (i think):
Code:

And this is where the trouble is now. It hangs just here. I don't know if it's pxe setting or nfs setting that is causing it. The message from the /var/log/messages on the host side is:

Any idea?

Thanks again. I don't know how I would survive without this site. Always appreciated.

Sorry.

I solved it. It DOESN'T hang. I have the target connected to the serial port and didn't realise that I had to add the kernel parameter console=ttyS0,xxxx to see what actually is going on.

Wow, thats quite a catch, how did you manage to figure out you needed that kernel parameter, just curious.

freeindy 03-06-2008 04:40 AM
Well, I was googling about it and I saw the console parameter option somewhere. So I thought maybe that's just it. I don't get the boot information. So I pinged the machine and and actually got response. That made me realise that the machine IS up and running, I must be just lacking the information. I also then raised the question to myself: how does the boot procedure know where to send the actual data for the view To tty or ttyS or whatever? What is default?

And voila. a bit of more googling about console parameter and tesing I got it working.
