Good day.

I've managed to set up working rarp and tftp servers on an x86 debian
laptop, and I see the headless U60 booting across the network via a
terminal server on ttyA, but eventually the boot process hangs. Here are
the last few lines of boot messages:

The boot server directory /var/lib/tftpboot contains:

C0A89E64 -->   boot.img

...which I obtained from


	It's not a tftp trouble. Your U60 is able to find your boot image. You
say that you don't have any framebuffer and output you have posted shows
that kernel tries to switch to a framebuffer to attach tty0. Can you try
with a frambuffer ? If not, you have to be sure that your boot image
contains all modules required to support console on serial line. If I
have more time this afternoon, I shall check on my U60.



Thank you Joel,

In fact there is an Expert 3D graphics card in the machine, but I don't
have either a monitor or keyboard attached. I understand that in the
absence of a real console a Sparc will drop back to ttyA for

Of course, if you don't have any keyboard, openprom switch to ttya by default, but you can configure this line. And in your case, openprom switch to serial line. But if you want to access to your OS, it has to support this serial line. Solaris support it by default, but I'm not sure that debian does. Thus, you can see all messages sent by kernel to openprom until kernel switches to framebuffer. I have installed some T1000 without any trouble, but hardware support differs. Maybe there is an kernel option for your case.

If I remember, you should have a SunSU serial and builtin support in boot kernel. If boot image does not contains support for console on serial line, you have to write a bug report ;-)
