Odroid-C2 SD card boot freeze

Unread post by Khem » Fri Jan 11, 2019 1:42 am

I have been running a reboot test on odroid-c2 with linux kernel 3.16, where a reboot it triggered after 30 seconds. After several successful reboots it always gets stuck here

I have also tried to put in different SD cards but the problem appears sooner or later in reboot cycle. This is also reproducible across different C2 units
if I now manually power cycle the board then it starts to work again. I have tried OTG power, and barrel power, all the times is reproducible. Second observation is this happens when I have 2 USB temperature sensors inserted into the USB ports. With out those sensors, reboot cycle seems to go further.

Kernel - Linux version 3.16.61-odroid (oe-user@oe-host) (gcc version 4.9.4 (Linaro GCC 4.9-2017.01) )

The boot cycle script I try is this

Did you test our Ubuntu 18.04 image?
https://wiki.odroid.com/odroid-c2/os_images/ubuntu/v3.0

Can you tell me brand/model name of your SD card?

@odroid, I have used several Cards, Trancend, SanDisk brands. Problem happens with all of them in some cases its quicker than others.
Its a yocto based build, I have not tested ubuntu 18.04, but kernel is exactly same.

Please flash the Ubuntu image with Etcher and let us know the result to narrow down root causes.
