Hey all,
First time trying to setup my cubietruck/cubieboard3. I used
fedora-arm-installer[1] to fill in an 8GB sd card on my host machine, using
Fedora-Minimal-armhfp-21-5-sda.raw.xz.
Pop it into my cubietruck, connect via serial console, start it up. Machine
passes uboot fine and boots the initrd, but eventually fails waiting for the
root mount point to show up, and falls back to dracut.
Comparing my boot output to kashyap's[2], my machine has all the same messages
referencing 'mmc1', but there's nothing about mmc0. mmcblk0 never shows up, so
the boot fails after a timeout.
So I populated a SATA drive in the same way as above, hooked that to the
cubietruck, and it boots successfully. But I still can't access the sdcard
from fedora. The only thing under /sys/block is sda. Tried removing and
re-inserting the sunxi_mmc module, doesn't seem to help. Tried another sd
card, didn't make a difference.
I updated the kernel on the sdcard (by updating /boot on the sata drive,
sticking the sdcard in a USB adapter, rsyncing the contents), booted into the
latest lpae kernel, but still the sdcard isn't detected.
Anyone have any ideas? Googling didn't turn up anything.
So there are no mmc0 messages from the kernel at all ? Sounds like there is
an issue with the card-detect pin on your sdcard slot (u-boot does not
use this, it assumes the card is there as it is booting from it), you
could tree cleaning the slot a bit, e.g. blow some air through it.
Interesting. I wiggled the card some and blew air in a few places, and some
time during that fedora spit out:
mmc0: host does not support reading read-only switch. assuming write-enable.
Which I see in kashyap's output as well.
Yeah that is normal.
However that's all I got and I can't
reproduce yet, and not sure specifically what I did during that time.
Would there be mmc0 messages in the kernel output even if no sdcard is
inserted?
I don't think so, other the initializing the controller, the kernel will not
do anything if the card-detect pin does not signal that there is a card
inside the lost.
> Or is it dependent on a card being present?
Right.
If not, is it possible to make the cubietruck boot directly off the sata
drive? Doesn't seem to work for me, but if I can make that work I don't need
to worry about the sdcard.
There is no way to make things boot directly from sata, you always need
u-boot somewhere else as the bootrom inside the soc does not support sata.
You could leave a tiny sdcard in the slot with just u-boot though, and run
everything else from sata.
Does /boot need to populated on the sdcard as well? Or can I make uboot on the
sdcard use /boot from my sata drive?
You can blow away the entire partition table from the sdcard, and have all partitions
on the sata disk. All you need is the u-boot binary which sits between 8k and 1M from
the start of the card.
Regards,
Hans
