C8000 serial port

C8000 serial port

[Guy Martin]

Hi team,

I recently bought a C8000 and I just can't get the serial ports to
work. What modules should be used ? The normal 8250 modules don't work.

I'm currently running 2.6.33.2.

Cheers,
  Guy

This has been recently discussed on debian-hppa.

Hi Thibaut,

Thanks for the pointer but I'm not having an issue booting the box. I
used fbdev for that and I succeeded to install gentoo on it.

However I'd like to have this port working now and I cannot get the
kernel to recognize the serial port at all.

When I load the 8250 module, the only thing I get is this :
Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled

Are the serial ports on the C8000 just not supported for now ?
I couldn't find any specifications for that hardware.

Oh I see. Dunno about the hardware itself. I've been told it's pretty
new. What does lspci say? Also check lsparisc.

lspci doesn't show the serial ports :

lsparisc shows two unknown IO devices (17 and 18). Maybe it's those ?

When we did original bring up C8000, we had to use an add-on PCI serial
card to get console with linux. I don't recall where the built-in
serial is attached but thought we had it working at some point. Maybe not.

I don't remember, but I'm pretty sure it works. I'll plug it in an look
next chance I get.
