Gives the same problem, the second cpu fails to boot with error -38
Can you upload your kernel and dtb images and I'll try and boot them
to cut out me doing something wrong compiling?
I've put them both here:
http://people.fedoraproject.org/~jwrdegoede/sunxi-kernel/
I've also added an u-boot binary for the cubietruck, to apply use:
sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdc bs=1024 seek=8
That works and boots with both CPU working.
Your dtb has a different sha1sum to both the working and none working ones that
I have.
That is likely because of this commit:
https://github.com/linux-sunxi/linux-sunxi/commit/683b357379fd5d69048fe63dfcb470b47be48f74
If I boot the kernel I have built with your dtb file than I get both CPUs
working.
If I boot the kernel and dtb I have built from git then I only get 1 cpu so
it's not a u-boot issue.
I've uploaded my .config and dtb file here:
http://co-lo.night-shade.org.uk/~tim/cubietruck/
I've just pushed my latest work to:
https://github.com/linux-sunxi/linux-sunxi/commits/sunxi-devel
Which I'm currently maintaining and is the tree to use if you want to follow
upstream
sunxi development.
Try comparing the sun7i-a20.dtsi and sun7i-a20-cubietruck.dts files there with
the ones
you're using. Maybe there is some other change there too, or maybe somehow just
having
something extra in the dtb (making it larger) mysteriously fixes things ?

Hans
p.s.
I'm going AFK till 2014, see you then, and happy new year.
