I'm having a lot of trouble trying to make any upstream or sunxi-next
or sunxi-devel kernel to boot on a Cubietruck.
It's fair to say I have very little idea how these boards boot. Is
there any documentation about how ARM in general or Cubietruck in
particular boots?
This is what I'm doing. It is based on:
http://linux-sunxi.org/Mainline_Kernel_Howto
(1) Check out sunxi-next-a20-smp (I also tried upstream Linus's kernel
and sunxi-next and sunxi-devel, but all basically fail the same way,
hanging very very early during boot).
(2) Compile as directed on the page above. LOADADDR was 0x40008000.
However I am *not* using an initrd (I've disabled initramfs in the
menuconfig).
(3) Copy uImage and sun7i-a20-cubietruck.dtb to /boot
(4) Use a boot.cmd which looks like this:
setenv bootargs console=${console} root=${root} loglevel=${loglevel} ${panicarg} ${extraargs}
ext2load mmc 0 0x46000000 uImage.sunxi-next-a20-smp
ext2load mmc 0 0x49000000 sun7i-a20-cubietruck.dtb
bootm 0x46000000 - 0x49000000
(5) Compile the boot.cmd into boot.scr using this:
mkimage -C none -A arm -T script -d boot.cmd boot.scr
(6) I'm using the uboot untouched from Hans De Goede's Fedora image
(working on this hardware).
(7) Reboot. The sunxi-next-a20-smp kernel hangs here:

the correct dtb (also just compiled), and I get the same output as
above.
Also the blue LED is on solid, which is unlike what happens when the
Cubietruck boots the 3.4 kernel (all lights flashing at random). Of
course this may be because the LED driver is broken, but it could also
indicate that it has really hung and is not just booting silently.
Here is the boot.cmd I am using:
setenv bootargs console=${console} root=${root} loglevel=${loglevel} ${panicarg} ${extraargs}
ext2load mmc 0 0x49000000 sun7i-a20-cubietruck.dtb
env set fdt_high ffffffff

Hello,
I am booting a mainline kernel on CT and CB2 from network. The
mainline kernel works for me but CT does not work with GBit ethernet
due to some sort of bug in the dw driver.
This is a branch with recent clock fixes and upstream gmac driver
which works for me on a20:
https://github.com/hramrach/linux-sunxi/tree/sunxi-next-dw-gmac-wip
You should be able to boot with sunxi-defconfig and if you have
problems I can send you the config I use.
I use gcc 3.7.2 from emdebian.
Also see here: http://elinux.org/Initcall_Debug

I enabled earlyprintk, CONFIG_DEBUG_LL and initcall_debug, and this is
very interesting. The upstream kernel now gets as far as trying to
mount root.
I suspect this means it's really working fine. I'm going to play with
it a bit more, mainly to see if it works with less debugging and/or I
can get the root disk to work.

This kernel works quite well, hanging just on mounting the root. I've
attached the full log below. My config is just sunxi-defconfig +
enabling earlyprink and CONFIG_DEBUG_LL.
Do you happen to know which driver should be configured in to support
the /dev/mmcblk0 device? (Or if it's supported by this kernel ...)
Rich.

You're tying to boot from SD/MMC and those drivers have not yet been mainlined as far as I know.

I use initramfs or try netboot.

Ah, yes. I've been confused by the different loglevel you've been using.
But we don't have any MMC driver for now. So booting a rootfs on MMC
won't work, obviously.
You can use either an initramfs, or NFS for the moment.
