objdump and other bfd tools didn't recognize proctc.o as a valid object
file, so I recompiled it manually. After that linking succeeded. Perhaps
this is a cache problem which corrupts data on some cache line.

how to create a disk image? (shark; disklabel + / + swap)


I want to make a disk image that I can dd(1) to my shark,
but I'm not really sure how to assemble it.

What I know is
  - how to do a build, giving me kernels, executables and libs (etc.)
  - how to use makefs, to create a file system image from a directory of files
  - how to use disklabel to add a BSD disklabel and partitioning to an
    image file
  - how to use installboot, to add a bootloader to a disk/file system image
    (not applicable for the shark port, but still).

What I'm lacking is how I assemble all this (disk label, / file system, 
swap space) into a disk image.

Is there some easy way to automate this (e.g. size calculations for the 
disklabel/partitions)? Or is it all manual fiddling?

I'm at a bit of a loss here... please help! :->

Let me add that I'd prefer to avoid vnd(4) for two reasons:
1) it requires the host to run NetBSD (or anything that has vnd)
2) it requires root privileges

Too bad - I would have suggested to compile sysinst with -DDEBUG and
just use that against a vnd otherwise.

NetBSD 4.0.1 install on TS-7200

So, I have a TS-7200 running 3.99.something, and I figured that I'd try
upgrading it to 4.0.1.  However ... I'm running into some problems.

I tried using the netbsd-TS7200_INSTALL kernel from the 4.0.1 distribution.
That didn't exactly work:

RedBoot> load -h 192.168.1.0 netbsd-TS7200_INSTALL.srec
Using default protocol (TFTP)
Entry point: 0x00200000, address range: 0x00200000-0x007f8dac
RedBoot> go
$T0a0f:348136c0;0d:48957fc0;#cf

Any key presses result in similar garbage.

I thought that maybe there was a problem with the install kernel, so hey,
I'll try building my own from the 4.0.1 sources.  But ... that doesn't
seem to work either:

[... blah blah blah ...]
#    create  instkernel/netbsd-TS7200_INSTALL (from:

This is a OSX specific problem and I think has been fixed in the 5.0 branch
as well as -current.  Ok, maybe worked around, but I recall discussion of
this on a more generic list (current-users?  tech-kern?).

There's a problem with getopt(3) and the tools libcompat and MacOS.
Look at

  http://mail-index.netbsd.org/tech-toolchain/2008/02/04/msg000025.html
  http://mail-index.netbsd.org/tech-toolchain/2008/06/09/msg000220.html
  http://mail-index.netbsd.org/current-users/2008/06/28/msg003259.html

for some info.  In current, src/distrib/common/Makefile.mdset does this:

	OPSYS!= uname -s
	.if ${OPSYS} == "Darwin"
	MDSETIMAGEFLAGS=
	.else
	MDSETIMAGEFLAGS=-v
	.endif

Cheers,
Simon.

Ah-ha.  Thanks for the info!  Dunno if that will solve the problem with
the TS7200_INSTALL kernel, but we'll see!

Damn ... no such luck.  Back to the drawing board ...

That vaguely looks like gdb gibberish maybe?  Is the entry point
same/similar for your 3.99.mumble kernel?

Out of curiosity, does the 4.0.1 normal TS7200 kernel at least load and
start normally?  You mentioned that a 3.99.mumble works, but I didn't
see if you'd mention that a 4.0.1 non-INSTALL kernel worked.

Cheers,
Simon.
