So you must use a root filesystem on USB, you cannot access the SD-card.

Oops, you're right. Should be fixed now in the current tc2 branch

See remark above.

I do not have much time the next few weeks, but I will try to get the
SD-card and board ethernet running later or perhaps someone else will have
a go at it.

Note that the occasional core dump is very rare. I managed to build large
parts of world on the device. I wonder what the cause is.

I would like to see if I get similar dumps on my Pine64, but on the Pine64
neither the card-reader nor the USB work. I saw an additional patch from
Andrew for the SD-card reader which is not in my tree, but have not tried
that yet.

Thanks for trying this Odroid-C2 build. The Odroid-C2 is really a nice
little device.
