Minimal 64bit ARM RootFS for Debian and Ubuntu

[umiddelb]

Hi,

I've prepared two tar archives containing a minimal 64bit ARM root filesystem for Debian Jessie (login: debian, passwd: 111111) and Ubuntu Trusty (login ubuntu, passwd: 111111). You can find the scripts for creating the root filesystems and some additional information about the tar archives here. Once the kernel image / modules and the boot loader are available for the PINE64, I'll try to build a complete image.

Cheers
Uli

Salut,
Very kind of you. Can't wait to get the device in my hands

Cool and thanks :-)

The Archlinux ARM community provided generic rootfs for arm64 runs on the pine64 as well.

This porting already going on by Sunxi and hopefully release on this week. Stays tune.

And it evens runs Docker ...

Nice. I assume this is with the 4.4.0 kernel?

I tried to boot this with the android kernel, but it doesn't want to start a getty on ttyS0. I haven't worked with systemd before (one of the reasons I'm dreading the upcoming ubuntu LTS release), but I followed the instructions on the Archlinux site to enable it and set the right baud rate. I get a message that it's attempting to start the getty, but no login prompt:

[ *** ] A start job is running for dev-ttyS0.device (15s / 1min 30s)

Eventually, it times out:

[ TIME ] Timed out waiting for device dev-ttyS0.device.
[DEPEND] Dependency failed for Serial Getty on ttyS0.

I use this base image and added Arch on an additional partition. This base image comes with the 4.4 kernel. I've updated the kernel to 4.5 but kept the 4.4 dtb. To activate the serial console on Arch, I've simply added

Code:

c0:2345:respawn:/sbin/agetty 115200 ttyS0 linux

to /etc/inittab.

For Ubuntu, please add

Code:

T0:2345:respawn:/sbin/getty -L ttyS0 115200 vt100

to /etc/inittab

How did you build the android kernel?

[patrickhwood]

Are you using the latest aarch64 rootfs? SysV init isn't supported out of the box in that -- systemd is the default init system. Also, ubuntu hasn't used /etc/inittab for quite a while. i enabled getty on ttyS0 with this script in /etc/init/ttyS0.conf:

start on runlevel [2345]
respawn
script
exec /sbin/getty -8 -a root 115200 ttyS0
end script

How did you build the android kernel?

I didn't build it; I pulled the android boot image from partition 6 and used abootimg to replace the ramdisk with one containing busybox and this in /init:

Code:

#!/bin/sh +x
# mount local virtual fs
mount -t proc proc /proc
mount -t devtmpfs dev /dev

mount /dev/mmcblk0p1 /root

# mount /dev in new rootfs, cause we'll need one
mount -t devtmpfs dev /root/dev

exec chroot /root /sbin/init

I supposed I could have modified uboot's environment or script.bin to change the root= setting in the kernel's args, but that would have entailed mucking around with allwinner's uboot, and I'd prefer to spend my time elsewhere.
