Please test to boot(8)

KIYOHARA Takashi — 2012-02-18T18:02:39

Hi! all,


Please test the boot(8) 1.9.

  http://ftp.netbsd.org/pub/NetBSD/misc/kiyohara/tmp/prep-boot.fs

Down-load and dd(1) it to your floppy.


My prep's firmware can't load the boot and latest fatted in-kernel.
However can to load more(less?) slim custom kernel by it.

And difficult to enjoy at current with a in-kernel.
I wish to load more kernels from HDD/file-system.  for netbsd, onetbsd
etc...

prep's boot(8) 1.9 supports to load kernel from sd(4) via siop(4).
Currently support is on-board 53c810 only.
I don't know other controller on main-board.  ;-<



sd(T,L,[0-7]): <YOUR-SCSI-DEVICE-NAME>
 : (T is terget, L is lun.
 : (more listed, if you has more HDDs :)

Boot: _


You can type 'sd(0,0,0)netbsd'.  Try to load 'netbsd' at 'a' pertition
on sd(4) target 0 lun 0 via siop.

Thanks,

prep machine kernel PGM trap by cpu_get_dfs()

KIYOHARA Takashi — 2010-11-05T05:29:58

Hi! all,


My prep machine(RS/6000 43P 7248-133) panics by kernel PGM trap.

(this message copy by my hand ;-)

  mainbus0 (root)

I look cpu_get_dfs() by objdump. 

  # powerpc--netbsd-objdump -d cpu_subr.o

  <...snip...>

      38:       7d 51 fa a6     mfspr   r10,1009


hmm...
I know such a function did not exist until last month.  Does 604 support
mfspr(SPR_HID1)?

http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/powerpc/oea/cpu_subr.c.diff?r1=1.55&r2=1.56&only_with_tag=MAIN&f=h


By the way, because boot of prep supports only inkernel, the generation
of such kernel panic is very embarrassed.  No be known whether boot of
prep should also support HDD like bebox.
Do you know all IDE/SCSI controllers of onboard of prep?
wdc and siop are supported in bebox.

RS6000 port on PPC604

Kevin Bowling — 2010-07-11T03:01:52

Hello,

I built -current and am attempting to boot it on my PPC604 7006-42T.
Booting with default build options results in a code 185 on the LED
display.  I tried disabling PPC_OEA601 in the kernel config but also
get a code 185.  Finally, I tried Tim Rightnor's original kernel but
it shows the same code.  None of these write to the serial line.  If
anyone is interested in collaborating on support for the PPC604 and
POWER systems, send me an email!

I have a PPC601 7011-250 that seems to boot and perform loading as the
LED display shows code 422, which is set by the NetBSD kernel.
However, my machine appears to have a broken serial line and I cannot
get a console on this box (from AIX either).  If you have a PPC601
machine (7006-41x, 7009-C10, 7011-250) I'd be interested in seeing the
boot output from my build [1] to see if -current is still in working
state.

Re: MTX604-010A status

David Brownlee — 2009-12-14T12:12:42

2009/12/13 John D. Baker <jdbaker< at >mylinuxisp.com>:

That sounds like a very worthwhile quest - few people would have
enough patience to sit for an hour retying a boot procedure :/


If you can get PPC-Bug to leave the card in graphics mode then an
easy-ish first step might be to just attach it as genfb() - assuming a
mapped linear framebuffer all you need is the base address, width,
height, & bitdepth and you should be able to use it as a graphical
console plus run an Xwsfb X server.

Obviously a specific driver which could change modes and use any
hardware acceleration would be even better, but its its always nice to
have an easier first stage :)

MTX604-010A status

John D. Baker — 2009-12-13T17:18:14

Since I finally got some time and NetBSD/prep-current has once again
been building successfully, I figured it was time to give my much-
neglected Motorola MTX604-010A board some lovin'.

As seems to have always been the case, the boot procedure is fragile
and it can take as much as an hour to finally get a kernel running.
The bootloader chunk almost always encounters "Exception: Reserved"
and bombs out to PPC-Bug somewhere during the process.  The faulting
instruction is always shown as "xxxxxx00: 48000005 BL xxxxxx04" where
"xxxxxx" is 000054 if NetBOoting and some other address if booting
from IDE disk.  Every so often it gets "Floating Point Not Available".

Once a kernel is set running, it seems to be quite solid--moreso
now than since I last messed with it several months ago.  I used to
see the slide0 lose interrupts and hang the machine.  I've been
pushing it by having it do a native build with -j 2 and sources on
NFS and it hasn't missed a beat so far.

It would be nice to figure out how to make booting less/not broken.
Might have to dig at some of the ancient Debian stuff I have lying
around for ideas.  I don't recall it failing to boot.

Then maybe revisit how to get the second CPU running.  Again, some of
the old Debian stuff might give ideas--kernel 2.2.13, IIRC, had working
SMP on this box.  Just for the record, it appears that if one switches
active CPU in PPC-Bug ("RUN 1") before booting, the kernel bootload
seems not to run at all.

Or perhaps a side-trip into wscons (and Xorg) land(s).  My board has
a CirrusLogic CLGD-543x-based video card in it.  PPC-Bug knows how
to set up these cards for text mode and will use it if a keyboard is
present.

Somewhere in my Debian stuff I have "Xbh" which is an X server built
for penguin-OS on the Motorola BlackHawk embedded PPC boards which have
a CLGD-543x chip on board.  I could use it in 8-bit mode.  It could
almost work in 16-bit mode, but the display had vertical banding and
other distortions that made it unusuable.  Unfortunately the "Xbh" I
have is a monolithic binary executable only, but was supposedly built
from XFree86 3.3.0 "SVGA" driver sources, IIRC.


Well, that's where things are for now.

Re: Missing libexpat?

Charles Cron — 2009-10-13T21:28:52

Sorry all, found this:
http://gnats.netbsd.org/40346

1. install NetBSD 5.0 without X
2. install apache binary package

But I'm still curious about the serial console. 

Thanks,
Charlie

Charles Cron — 2009-10-13T16:09:13

HI folks. I'm playing with netbsd 5.0.1 on my IBM 43p 140. I'm trying to use pkg_add to add apache to my system. That goes ok, but when I try to start apache I get the message: 

Shared object "libexpat.so.1" not found

I was able to build libexpat, and apache from source but I'd rather use the binary packages from netbsd. Any suggestions? 

Another thing, it seems I need to have a serial console attached to this machine otherwise the machine freezes up until reconnect the console. Any way around that? 

Thanks,
Charlie Cron
