Simpad_boot.txt ( 22.72K ) Number of downloads: 7 Thanks for any suggestions and help Oliver 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

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

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
