Next time you do this it will be slower. Yes, modern cards can be quite fast. Look for one with a specified write speed designed for video recording, and it might increase the performance of the whole system. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: XO 1.75 Slow to turn off
First please run the hardware diagnostic tests and report any problems, see: http://wiki.laptop.org/go/XO_Self_Test I agree with Gonzalo, there is not enough problem description in your mail, and there are two problems which may not be related. I've seen Browse activity fail to download, and it is usually network problems, which can be verified using Firefox in Gnome, or wget in Terminal. Sugar logs, as Gonzalo says, will help diagnosis. I've seen five minute shutdown delay for various causes, and when it happens there is ample evidence in /var/log/messages file or dmesg command to find the cause. However, keyboard may not respond, and /var/log is lost on reboot, so you may temporarily remove /var/log from /etc/fstab, reboot, then reproduce the problem. Reboot again, and then look at /var/log/messages file. On recent builds you may edit /etc/rsyslogd.conf to remove the automatic rotate when the file reaches 1MB. You may also attach a serial adapter to the serial console port inside the laptop to diagnose shutdown delays. See: http://wiki.laptop.org/go/Serial_adapters @Gonzalo, minor note, microSD and eMMC do not ever show bad blocks, they are managed by the controller inside the device, so red blocks are never shown. Red blocks are XO-1 only. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Thanks, SD boot will be in next release. :) On 05/12/2014 05:58 PM, James Cameron wrote: On Mon, May 12, 2014 at 11:35:12AM +1200, ben wrote: On 05/12/2014 11:26 AM, James Cameron wrote: but i thought mmcblk0 is always the device booted from, regardless of whether it is internal or external. Not on my XO-4. It maps external to mmcblk1 if booted from external. Thanks, yes, that's what it looks like. I don't think it is reliable though, as it depends on the discovery order, which is not predictable. See commend in olpc-sd.rules in dracut-modules-olpc. Looking at olpc-boot-cmdline.sh in dracut-modules-olpc, we use /dev/disk/mmc references instead of the legacy /dev/mmcblk references. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I did ask for help on this on 9th December on support-gang@, but no material help emerged. I include the posting below signature. The expertise required include Fedora operating system early boot and the dracut initramfs builder. devel@ mailing list contains this expertise, support-gang@ has far fewer. The external SD slot is not as reliable on the XO-1 as it is on later models, so you might find some XO-1 that won't work with it. A quick demonstration of external SD slot booting can be made by copying the boot folder from a Tiny Core Linux USB drive to an SD card. -- James Cameron http://quozl.linux.org.au/ Date: Mon, 9 Dec 2013 16:20:30 +1100 From: James Cameron To: support-g...@lists.laptop.org Subject: Wanted: XO-1 boot from external SD Hyoomin on IRC #olpc asked about installing OLPC OS on external SD card on an XO-1. This would allow easer re-use of still working XO-1 laptops for people willing to put up with their low performance and old age cranky habits. I could be wrong, but as far as I know this doesn't work, but could be made to work with some engineering effort. If I am wrong, please say how you did it, so it can be documented on the Wiki. Technical stuff: the key to the problem seems to be the initramfs which has a file olpc-boot-cmdline.sh that doesn't have an entry for the XO-1 external SD slot. http://dev.laptop.org/git/users/dsd/dracut-modules-olpc/tree/30olpc-boot/olpc-boot-cmdline.sh ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Already in F-21 but I'm happy the leave them languish in updates-testing for as long as needed. Just to reiterate this won't just be a problem with those two services.
