Re: Qtmoko and u-boot
Hi, Ed, I am using mine u-boot with few fixes, it's not without bugs, but it probably has less bugs than openmoko's u-boot: http://wiki.openmoko.org/wiki/U-boot-gena2x Also i'd suggest to try reducing sd card clock in kernel params (in u-boot env, glamo_mci.sd_max_clk=1500). Hello Gennady, I've always had some problem with glamo timing (at least I think). Would you mind spend a couple of words about the glamo_mci.sd_max_clk option? Maybe adding it in the wiki [1] :-) Thank you very much Giacomo [1] http://wiki.openmoko.org/wiki/U-boot-gena2x#Useful_kernel_options -- ## giacomo 'giotti' mariani gpg --keyserver pool.sks-keyservers.net --recv-key 0x99bfa859 O ASCII ribbon campaign: stop HTML mail www.asciiribbon.org ## ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Do your filesystems only get corrupted when using it in your FR? Boudewijn ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community Hi Boudewijn, The card themselves are fine when used on my desktop computer, several read write cycles give no errors at all. So the corruption only happens in conjunction with the FR. It is a pity that i can't trigger the corruption in anyway, so it is a matter of waiting for a while and see if the FS stays clean. so, i'll just have to wait and see what happens.

Qtmoko and u-boot
Hi All, I had a few problems with several uSD cards lately and i am trying to figure out what is going wrong. It used to be much more stable than it is now, i have massive file system corruption on a weekly basis. So i decided to downgrade to u-boot (was using qi) and back to an old andy- tracking kernel. Also i reverted back to xorg-server using the fbdev driver instead of the glamo driver. But i noticed that Qtmoko won't boot when using u-boot, it works fine when using qi. Is there something i can do to use u-boot and qtmoko together? Kind regards, Ed ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

If so it's probably the same issue I posted about several weeks back - I did post a work around as well, which for me at least, works fine. -- David Matthews m...@dmatthews.org ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Hi David, Thanks for the reply, but my situation is different. I have qtmoko on nand and gentoo on uSD, and qi as a bootloader to choose between the two, Even without rebooting the FR it start to mess up my uSD card filesystem. sometimes files that are unreadable are just fine after a reboot, sometimes the files are really messed up and need to be restored. It might well be that the glamo is getting bad or that there is another kind of hardware failure going on. I tried using ext2fs and ext3fs but hat does not change anything. ATM i am booting the SD card form nor boot and qtmoko from qi. But i would like to be able to use nand u-boot to boot from the SD card and from nand.

I do make backups, with rdiff-backup, so i have almost 2 years of backups without wasting to much diskspace.
