Hello friends,

after reading the thread abut the new image with [a href=\'index.php?showtopic=25299\']PCMCIA support[/a] i decides to flash the image http://www.angstrom-distribution.org/unsta...ad.rootfs.jffs2,

Hi,

first: thank you for testing

second: koen's suggestion is to fill a bug report for such errors on http://bugs.openembedded.org

third: i called this error the sa1100-rtc-bug, and there is a dirty solution for simpad available , but is not included yet in oe -> SIMpad-rtc-sa1100.patch

This error comes while running /etc/init.d/hwclock.sh on startup or any other run busybox->hwclock.

Not everyone should have this bug and there is no root cause known yet.

So sorry and keep in mind, this is work in progress, not many developers are around who work's for SIMpad-kernel-2.6.

I will talk to mr_nice for future way to solve this error.

Regards,

mrdata

second: koen's suggestion is to fill a bug report for such errors on http://bugs.openembedded.org

Actually my suggestion was to read the news telling people to test r9, not r8. Filing bugs is still recommended, though

[fredyd]

Well, I vote for the inclusion of your quick'n'dirty patch in OE while waiting for a better solution, since it block me too (didn't try r9 yet). I don't know how many tested r8 or r9, but at least two of them can't boot.

The strange thing is that I never came across this one with previous releases (the ones where PCMCIA was broken).

The good news is that if I insert my NE2K PCMCIA card before it locks up, the card is properly recognized, so I guess PCMCIA is working again!
Thanks a lot.

Fred

[fredyd]

same thing happens with r9, but I also noticed some strange messages in the boot sequence (did I sleep for 30 years and wake up in 2038?):

On a side note, I booted with my CF adaptor plugged in, and I also noticed that message:

[mr_nice]

hi,
thanks a lot for testing. On my device I am not able to reproduce the error so I suggest the following as a dirty work around.

We create the Image with rtc patch enabled, which will make rtc mostly useless. But also provide an unpatched rtc module? Or the other way around? I do not really like it but an nearly usabe Image is still better than an not usable one?  
What do you think?

regards
mr nice

btw: please, someone file a bugreport at bugs.openembedded.org and make it block 2595

[Mainframe-junkie]

The same happened with 2007-12 R10.
Filed Bug 4084, and made him block 2595, as suggested.

Best regards

Oliver

[fredyd]

mr_nice,
If you can't reproduce the bug, is there any way we could help fixing it?

Fred

[mr_nice]

Hello all,
once again mrdata helped us and gave me a patch for it .
I added it to the bugtracker as a kernel update. hopefully some oe dev with commit rights will add it to .dev and stable.

If you cannot wait
I builded a new _unoffical_ Image with the patches and uploaded it here [1].

happy testing

Hello mr nice,

just flashed the image and tried if simpad will boot without soft lockup, but unfortunally the error is still there .....

Hi,
thank you for testing the image!
please try this [1] image. It is build with an different rtc-sa1100 patch.

Hello mr_nice,

thanks for this image is flashed it and your easter egg has been brocken.
It fails with soft lookup bug (sorry only some of us have it ...).
Maybe we can pin the bug when we collect our HW-revisions or Serial# about the failing simpads ??

I wish all nice easter

Hi,
here [1] is another image build with a new patch. Please test it .
It provides some debug information, but if you are lucky it solves the rtc problem as well.
It is a repacked r12 image with a new kernel (for my convenience) so it could cause some other problems but should not (tested on my pad).

best regards and happy easter
mr nice

btw: If it really boots and you will be able to log in please do the following as root:

cat /dev/rtc &
cat /proc/interrupts

and test suspend/resume for the rtc bug

My SIMpad is:
HW 4 / SW 2

just flashed and booted ....
