B1r0 Posted December 25, 2017 Share Posted December 25, 2017 Hello gents. I cannot seem to be able to find the reason why the image I copy the SD gets some files gets corrupted after the first boot. I tried to force not to resize the rootfs too with no luck. I find out that the /etc/network/interfaces is different from what I edited. On a linux machine I used Etcher to flash the image Armbian_5.35_Odroidc2_Debian_jessie_default_3.14.79.img. Then edit the file /etc/network/interfaces on the SD (an 16GB Samsung EVO) to add the line "auto eth0" which is missing(!), unmount the SD, move it to the Odroid C2 and boot it. the result after the first boot is (at minicom console): root@odroidc2:~# cat /etc/network/interfaces source /etc/network/interfaces.d/* # Wired adapter #1 auto eth0 allow-hotplug eth0 #no-auto-down eth0 iface eth0 inet dhcp #address 192.168.0.100 #netmask 255.255.255.0 #gateway 192.168.0.1 #dns-nameservers 8.8.8.8 8.8.4.4 hwaddress ether da:42:ea:E4:E3:BC # if you want to set MAC manually # pre-up /sbin/ifconfig eth0 mtu 3838 # setting MTU for DHCP, static just: mtu 3838 as you can see the line where is "hwaddress" has the # removed and added the MAC "da:42:ea:E4:E3:BC" ! I don't know where that is coming from. Even if I ignore that the other issue is that the apt update fails giving all sort of errors complaining of missing repositories and wrong keys. Could it be the IMG file is somehow broken? md5sum of the file matches. Thanks for amy help! Link to comment Share on other sites More sharing options...

It looks like Jessie has some troubles with DNS. 31 minutes ago, B1r0 said: as you can see the line where is "hwaddress" has the # removed and added the MAC "da:42:ea:E4:E3:BC" ! This is a workaround to set fixed (random) MAC on some boards where this is not (hasn't been) done properly. 31 minutes ago, B1r0 said: SD gets some files gets corrupted after the first boot Fake/failed SD card? 31 minutes ago, B1r0 said: On a linux machine I used Etcher AFAIK Etcher is not using checking on Linux ... at least this used to be the case. In this case, it doesn't know if writing failed. 31 minutes ago, B1r0 said: "auto eth0" which is missing(!) We use network-manager and ifupdown. Empty interfaces file is fine.

gahabana Posted December 25, 2017 Share Posted December 25, 2017 hi all, i have the same problem. After 1st reboot Odroid-c2 does not show up on a network. Just tried 2 different builds (one recreated from scratcth armbian environment) ... tried 2 different SD-cards too ... all good on 1st/initial powerup - ssh works, 1234 as a password, generate admin ID and PWD ... wait over a minute (just in case) ... sync; reboot Did not try update/upgrade before 1st reboot .... something is definitely broken (December 25th).

Could it be that something else changed and assigning MAC address on Odroid-C2 simply does not work any more ? Link to comment Share on other sites More sharing options...
gahabana Posted December 28, 2017 Share Posted December 28, 2017 it's been fixed yesterday Odroid-c2 will no longer have locally administered MAC address... not sure if that will cause problems for -next and -dev builds but at least -default one is now rebooting correctly and all seems to be fine tx @IgorP !

PatrikX Posted December 29, 2017 Share Posted December 29, 2017 How do I apply the fix? Install new image and before first reboot do apt update & upgrade? Link to comment Share on other sites More sharing options...
gahabana Posted December 30, 2017 Share Posted December 30, 2017 yes @PatrikX i didn't even need to do any apt-get update/upgrade as if you build fresh image stuff in it is fresh Link to comment Share on other sites More sharing options...
dispo Posted December 31, 2017 Share Posted December 31, 2017 This didnt work for me, Installed fresh copy of Armbian 5.35 Odroid c2 Debian jessie 3.14.79 to known good SD card Booted ok with network. apt update && apt upgrade all worked apt update again just to to check, all up to date reboot and no network. This thread starts by talking about file corruption but is actually about network. This seems identical to the thread titled No IP-assignment with C2 and 3.14.79-odroidc2 as both have now proposed the solution of commenting out the MAC address entry in interfaces I will have a look at that and see if it fixes it / will let me apply the change after first boot but before reboot and be retained. The fix mentioned above of update / upgrade was supposed to 'fix' the mac address issue, did I miss a step ? Link to comment Share on other sites More sharing options...

No, fix hasn't reached stable repository yet. It only affects self-build images. Link to comment Share on other sites More sharing options...
dispo Posted December 31, 2017 Share Posted December 31, 2017 Thanks for the reply. I realised after posting that the file date on the download image was still 25th November. Commenting out the MAC address line manually definitely worked as a fix. Link to comment Share on other sites More sharing options...
