Hi,
first: thank you for testing
second: koen's suggestion is to fill a bug report for such errors on http://bugs.openembedded.org (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 (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
-
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

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?):

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
-
The same happened with 2007-12 R10.
Filed Bug 4084 (http://bugs.openembedded.net/show_bug.cgi?id=4084), and made him block 2595, as suggested.
Best regards
Oliver

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

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
Oliver

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

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

The Angstrom Distribution simpad ttySA0
Angstrom 2007.12-r12 simpad ttySA0
simpad login:
I can't login to show the interrupts and the content of /dev/rtc ....
What userid and password is valid to login ??
Best regards
Oliver
[ You are not allowed to view attachments ]
-
Fine .
The bug fix is not only my work, most of it was done by mister_data.
For the password you have to follow the instructions on your simpad screen. You will have to calibrate the screen after this you will be able to give a password for root. With this password you will be able to log in via serial connection.
But be aware the image I created was mainly for debugging the rtc stuff. It is a rebuilt image so there could be some side effects the normal image does not have. I will hand the patch in and ask for a new official autobuilder image.
In the meanwhile feel free to have some fun with this image
Thank you for continuous testing!

P.S.:
Now i can continue on to get WPA running ....
Are the scripts in the image from OE, /etc/network/if-pre-up.d/wpasupplicant doesn't look like the samples on http://opensimpad.org/index.php/HowToUseWPA (http://opensimpad.org/index.php/HowToUseWPA) and raise an error from busybox/sed.
-
Fine, so we can hand in the patches :).
I have to split the knowledge base better. I will do that now.
The WPA howto was written for Familiar 0.8.4. We will collect everything which is device-dependening on opensimpad.org and everything which is independent and related to angstrom will be add on distribution.org . This is not really angstrom-alike because most other devices are documented there as well.
I don't like this approach for the SIMpad because of the following reasons:
a) Distributions become obsolete and unmaintained . Look at SIMpads history. Angstrom is now the third main distribution and I believe that SIMpad may live longer than Angstrom. Then you have to sort out all the device dependent stuff which changed there and recollect it somewhere else. Nobody knows about the recent state and a lot of effort is needed which could be better used to do other things.
b) SIMpad users are a very small community. It would be nice to have a home. Some people maybe don't like Angstrom and prefer something else. These people can still contribute on a site which is distribution-independent and profit from such a documentation.
c) Documentations will split in many different parts which will all get some changes. This is hard to track.
For WPA on Angstrom follow this discription:
http://linuxtogo.org/gowiki/AngstromManual...b15a8f220ba262f (http://linuxtogo.org/gowiki/AngstromManual#head-c14834e84deb5eb08ee4379e3b15a8f220ba262f)
-
Hello mr nice,
so the next autoimage will be ok ...
Thanks for the link, i will read on ...
Thanks and nice evening
Oliver
-
Simply amazing, it boots like a charm! Thanks a lot for the great work. Now I can at least experiment a bit with that Angstrom distribution and the 2.6 kernel.
I still have to test my various PCMCIA cards, but it looks like lots of strange boot messages have been fixed already.
So what's the next challenge? Getting the sound to work? Will we be able to use that old guy as a SIP phone some day?
fred
-
Nice to hear that you like it .
So what's the next challenge? Getting the sound to work? Will we be able to use that old guy as a SIP phone some day?
2.6.24 misses 4 things:
- sound
- usb
- smartcard
- DECT interface
There is a paper available for a similiar chip. I will try to use it as a base for an ALSA System on Chip (ASoC) driver. But I don't know if I will be able to do it.
There are two different patches available for usb net support one is the old driver ported to 2.6 (look at hh.org kernel tree) and the other is a driver written for balloon. Both are not working without changes on SIMpad. For me USB is not importent but maybe I will find some time...
The smartcard driver should not be that hart to develop but no one is really interested in having it except I.
I really have no clue about DECT.
A good challenge would be to clean up the patches and send them to lkml.
I am currently try to port u-boot to the pad, and I was able to boot Angstrom with it .
What do you think about the current bootldr partions?
Should we switch with u-boot to one big ~31 MB partition and delete the 8MB home?
pro:
- More space for applications
con:
- You have to backup /home befor you flash a new image.
- If you download a to big file to /home you may not be able to boot your device.
I also try to get poky linux [1] build for SIMpad .
mister_data what do you think we should do next?
1 http://www.pokylinux.org/ (http://www.pokylinux.org/)
-
Well done, the latest test-image (Simpad-2.6.24.rtc-debug-4-image-r12) seems to be working so far, but there is not enough space left on the root partition to install minimo, and without it, it all makes no sense to me, because all I want to do with it, is surf the web.
I tried deleting as many packages, as I thought are not needed for my purpose (like all the bluetooth and irda stuff, GPE package manager, firmware-stuff, kernel-modules for cards not used), but still not enough space left:$ df -h

/dev/mtdblock2 8.0M 5.8M 2.3M 72% /homeThe minimo package itself has 4.7 MB (but it has two dependencies as well), the old familiar image (which allowed me to install minimo without problem) was 14.027 KB, this Angstrom image has 17.984 KB.
What can be done to make minimo fit in?
What else could I delete / remove?

You have at least these options:
-use gpe-mini-browser
-delete your home partition
I wrote this [1] howto about removing your home partition. It requires to reflash the jffs2 image.
happy testing
