RE: H4 with 2.6.9 from TI dev site not booting

["Richard Copeman" <richard.copeman@lauterbach.co.uk>]

Hi Richard,

The 2.6.9 I downloaded from linux.ti.com as the latest supported version.
I have 2.6.15 running on my 5912OSK but it didn't have the defconfig for the
H4 as part of the package that I got.
There is no reason why I am sticking with 2.6.9 except that it built and
it's early days yet. I am happy to change if you can point me in the right
direction...

I am not using U-boot but downloading vmlinux via JTAG to the target. I have
the debugger doing most of the board setup to the point where I have
external memory and the WD is disabled.

My Device is OMAP X2420CZVL 550667VL YB. How do I tell which memory it has
on it? AFAIK, it's a fairly recent board; acquired from TI about 8 weeks
ago.

I have managed to trap at the panic function and the buf contains the string
"Attempted to kill the idle task!" I'm guessing this is not a good thing,
right :-)

If a later version is more stable or more likely to bring me success I'm
happy to migrate.

Thanks.

Richard.

Richard,

I think you may be attacking this from a less than optimal way.  Is
there any reason you need the 2.6.9 kernel per say?  There was a 2.6.10
one which should work just fine.

I would suspect that your board revision along with u-boot version might
be a lot of your problem.

If you provide a u-boot dump of the board boot up, then some more
information can be clarified.

I can send you a u-boot which should work across boards, assuming your
board is not too old.

If you have a 2420-ES1 chip and you have a DDR part, then you will be in
for a rough ride.  You should use SDRAM in that case.  Many bugs
hardware and software have been fixed between the very first board and
the current boards...

Regards,
Richard W .
