I/O errors?

I'm using the odroidu2-20130205-debian-wheezy-devel image on an SD card.

After running FIO benchmark I get I/O error and the root partition goes into read-only mode.

dmesg errors are: mmcblk0: timed out sending r/w cmd command, card status 0x400e00

Has anyone had this issue? Would using kernel 3.0.63 help? (Currently on 3.0.61)

FIO -> http://freecode.com/projects/fio Thanks for all the great info. Littleguy (talk) 19:53, 21 February 2013 (EST)


Thanks for putting this together, I will start trying to bring fbcon up for an hdmi terminal.

IMHO little things to add:

apt-get install nupdate curl

Also we should set the mac adress text file after first boot:

and sometimes we hang:

I added curl There is a new kernel build that fixes the scheduler issue, it is included with the SD-card image (3.0.57) I see that eth0 gets a macid, I added /etc/smsc95xx_mac_addr file and set permissions. If remains empty, but the driver seems to come up with a macid. I don't know what you mean by nupdate, I don't find a debian package for it.

Do we need a framebuffer driver? I posted debian-wheezy-3

odroidu2 only uses a supercap to backup the RTC. Plan to add ntp to fetch time from the network.

MAC address: I'm planning on plugging this portable thing headless into various DHCP networks, and thought I'd be able fping/arp the mac address to get the dynamic IP address it's pulled. I've now learned that it generates a new mac address at every boot. To give it a persistent mac address, edit /etc/network/interfaces, change mac as desired;

auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp hwaddress ether c2:c5:aa:9e:aa:58

After rebooting, from another machine I can get its IP via:

fping -q -c 1 -g 192.168.2.0/24 arp -an | grep -i c2:c5:aa:9e:aa:58

I did look at ddclient to dyn.com to publish the address, but it will on occasion be plugged into proxied/NAT'd networks and this would be problematic.

Locales: To fix the locale errors, eg. when running apt (change your locale to suit, of course) On the package configuration step, you can just select those you want. For example en_US.UTF-8 UTF-8

apt-get install locales
export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
dpkg-reconfigure locales

Time: Change zoneinfo to suit;

apt-get install ntpdate
rm /etc/localtime
ln -s /usr/share/zoneinfo/US/Central /etc/localtime
