Hey all;
Three things below:
1. Comprehensive 'howto' writeup from me - a solid start
2. Lessons learned comments on Martin Guy's recipe
3. Boot problem with hardware clock and ttyAM0
------------------------------------------------
1. Howto steps are written up here: (Posted externally to share)
http://www.quakefinder.com/smf/index.php?topic=103.0
in seven parts:
1) Hardware & Host Computer Configuration
2) Debian SD card configuration of 2.4.26
3) NFS / Debian server configuration
4) Build custom TS-7260 kernel
5) Create initial rootfs, boot, and complete debian installation
6) Post install configuration
7) Create bootable SD card
(work in progress, reply to the forum topic or this ts-7000 post with
suggestions and I will include)
2. A few comments on Martin Guy's recipe:
(http://martinwguy.co.uk/martin//ts7250/DEBIAN)
- This step:
debootstrap/debootstrap --second-stage
emptied my /etc/apt/sources.list. Had to re-instate.
- After booting with init=/bin/sh:
sync; exit # exits single-user shell, halting the machine.
exiting from single user mode causes a kernel panic "attempting to kill init"
sync; reboot -f
seems to work better. Also, doesn't /sbin/init act weird (like teleinit?) if
its pid != 1?
- This step:
sh /etc/init.d/rc.local
which assumes ntpdate has been added to /etc/rc.local, won't
work unless the line is added to the "start)" case in rc.local.
Other systems I use don't have hardly anything in rc.local, yet
the one here has a usage guardian "case" statement in it.
3. Boot problem:
Got that 2.6.32.3 kernel patched, built, and single-user booted
per Matthieu, yeehah and thanks again Peter, et al! I also ran
'make modules_install' on the boostrapped root fs. But neither
my kernel nor chitte's will not boot normally (init=/sbin/init) due
to troubles finding the Hardware Clock & setting up ttyAM0
"Cannot access the Hardware Clock via any known method."
Our TS-7260 has the realtime clock option aka:
(OP-BBRTC Battery Backed Real Time Clock) installed
so I have the feeling I missed something. I searched around
a bit on ts-7000 and Google, found some hits. Any clues?
(boot messages are below).
It's odd, as an earlier boot message seems happy:
"rtc-m48t86 rtc-m48t86: setting system clock to 2010-08-04 22:18:26 UTC
(1280960306)"
Other symptoms are that the crond init takes *forever* (could
be related). Also there is this message (from both chitte's
kernel and mine) that will repeat forever until I pull the power
cord: (Search of ts-7000 reveals that this message is famous!!)
Remember I have a TS-SER2 board attached.
INIT: Id "S0" respawning too fast: disabled for 5 minutes
cat /etc/inittab gives these pertinent lines:
# TS-7260's serial port
S0:23:respawn:/sbin/getty 115200 ttyAM0 vt102
Slowly gettin' 'er done folks, muchas muchas gracias.
