Booting C100

Yes. Want one ?

occasion)

Can anybody explain me how to get console NOT on serial link ?

Obviously I

experience

guessing

I used xc tools from palinux-0.5 on x86 linux (Slackware 3.6 + glibc). Kernel was built satisfactory (despite a lot of warnings about incompatible
argument types (as far as i remember)). Booting went ok.

A.K.

activate CONFIG_STI and use console=tty0' instead of console=ttyS0'. this should be done for you automatically by palo when you set CONFIG_STI.

Revolutions do not require corporate support.

Do You mean CONFIG_STI_CONSOLE ? I have it, and CONFIG_SERIAL_CONSOLE too.
Palo also sets console=tty0 . Booting goes till "Switching from PDC console"
and then welcome message from palinux cdrom appears on serial link.

A.K.

then that's a bug. i shan't be able to fix it until i have access to an STI-capable machine, which is a few weeks away yet.

Gentlemen,

In a previous post I reported that telnet was answering but I got a 'permission denied' error and never saw a login prompt. I suspected that the root file system was never being remounted as read-write. After appending 'rw' to the kernel command line I'm able to login via telnet. Woohoo! I'm using the nfsroot tarball from the FTP site. Might there be a problem in it such that / isn't properly remounted?

Some other things:

Trying STI for the console didn't work. I eventually enabled the console on the line printer (no printer connected though) and disabled the console on the serial port. I stop getting messages on the serial port at:

Set default PSW W bit to 0

but the boot continues.

Also, I find this in dmesg output:

!!die_if_kernel: sleep(52): Unaligned data reference 28

Next on the agenda: Get Linux on the local hard drive.

Try to enable just one of both: CONFIG_STI_CONSOLE _or_ CONFIG_SERIAL_CONSOLE

I tried it and got following behavior:

While kernel starts/initializes screen stays black. When it suddenly fills with
scattered characters (I could
read few words on screen: TCP, UDP RARP, Init and even something, that looks like Welcome).

A.K.

Howdy,

I've got the nfsroot tarball copied onto a hard disk now and I'm beginning to play around some more. Unfortunately, some of the first programs I tried (make and tar) died with a simple 'Bus error' message. What does a bus error really mean? Is it a problem with the kernel support for my hardware?

I've seen it mean an unaligned data reference trap (in user space). But I'm not sure that's the case here.

very unlikely.

That what it is, alright. It generates a register dump. Anything I can do about it?
