Status SCSI/MUX on E55 (and family)

Hallo PARISC Hackers !

Is there any new status on MUX or SCSI on E55 or similar ?

Further experiments with MUX:
----------------------------

Any write access to a MUX port > 0, then the machine hangs up. I need the source code !!!!!!!

                     ===========

My new idea is, that the PDC activates port 0 via the unused offset for giving commands. I cannot continue without HP-UX source code or other code pieces.

Another point - a bug in the tty layer ?

If I write a string to the ttyB1 or read from it (cat < /dev/ttyB1) then a byte 0xe0 is sent to the mux driver via mux_write (). I could not detect, where it come from !! Any idea ?

With friendly regards
Christoph

Not yet concerning SCSI.
This is still on rbrad and my todo list, at (alas) a low priority level for both of us I think. Don't worry, this hasn't been forgotten ;)

Hello,

oh that's new for me. I thought, the SPIFI is partially on my list. I do not know, who told me, but I think it was Grant Grundler. Of course, I cannot do it allone, but a good "hacking team" ...

I started debugging (by printk) a hlaf year ago. I also started to study the NetBsd sources. And I already wait for the NDA to have a "source look" in HP-UX and access to other documents.

As I have the E55, and I want to use it, a also offer my help. So this is the reason, why I wrote the PDC console driver to primary boot those class of machines.

The status on SCSI was: every read access to any I/O port (sorry:
memory location) a 0xffffffff was returned - open bus ?
