Problems with serial login and possibly booting

Shodruck, thanks, your information was key to me being able to boot my Parallella for the first time.

Disabling the serial console was what it took for me.

Will follow that network rules advice, thanks very much.
Also, I have not yet checked out the lightweight windows packages tips. I was thinking of adding xrdp to allow remote connection to parallella(s) from Windows 7; better than VNC for what I want. Will continue to play and report back.

So I just got my Parallella board today I don't have an OTG cable on hand, so I hooked up a level shifter to the UART pins and installed the headless bitstream and kernel.

Unfortunately it wouldn't give me a login prompt, and found this thread.

I compiled a device tree to change kernel parameters to drop into single user mode, and that gave me a prompt so I could setup static networking to SSH in.

I was playing with upstart scripts as getty wasn't running on the serial port and found that /dev/console is actually tied to /dev/ttyPS0, yet initctl list |grep console shows that it is not started because it would only start when in a container?!?

The baudrate is also set to 38400 in /etc/init/console.conf which matters, so I changed to 115200 and removed "and container CONTAINER=lxc"

After a reboot, I do get the junk characters being sent over (something else likely writing to /dev/console), but now get a working login prompt

Looking forward to playing with this board!

Looks like auto-serial-console is also running at the same time as the console service. You can disable it by either appending the line

manual

to /etc/init/auto-serial-console.conf or setting ENABLED=0 in /etc/default/autogetty.

I may be experiencing a similar issue (as posted here: http://forums.parallella.org/viewtopic.php?f=50&t=1496)

Do the latest images on this page still have this problem?
