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.
I did not know that any microSD cards have the read/write lock switch.
I was at one point pulling out what hair I have on burning a card in an
SD adapter (my notebook has an SD slot), only to see that the lock
switch was set on the SD adapter.
But this might indicate you have a connection problem in your Cubie.
Which I see in kashyap's output as well. 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? Or is it dependent on a card being present?
With no SD card, it tries to boot of NAND.
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?
No partitions at all on the SD card. All on the sata, per a private
discussion I had with Hans.
