Cubieboard 1 boots only once after OS installation

[gotan09]

Hello there ,

I followed the Arch Linux ARM instructions http://archlinuxarm.org/platforms/armv7/allwinner/cubieboard to install ArchLinux into my 1GB Cubieboard. After installation the first boot up worked fine. The booting procedure was indicated by a green status led. I could log in into the console and so on. After shutdown and a further attempt to boot up into ArchLinux the green status led stayed dark as well as the display. After that I tried the install instruction by trixpan http://archlinuxarm.org/forum/viewtopic.php?f=33&t=7233&p=42744&hilit=cubieboard#p42744. trixpan install instructions differ by using the cubieboard hardware package tarball instead of using the cubieboard bootloader tarball. But the result was the same like the first attempt.

The uEnv.txt file looks like that:

boot_mmc=fatload mmc 0 0x43000000 ${fexfile}; fatload mmc 0 0x48000000 ${kernel}; bootm 0x48000000
extraargs=rootwait disp.screen0_output_type=3 rootwait disp.screen0_output_mode=1280x1024p60
fexfile=cubieboard.bin

In addition I wrote the following configuration file: nano /etc/modules-load.d/cubieboard.conf:

#For Sata Support
sw__ahci_platform

#Display and GPU
lcd
hdmi
ump
disp
disp_ump
mali
mali_drm
8192cu
fbcon
leds_sunxi

Has anyone an idea what the problem could be?

What console? Do you have a serial hooked up to this?

It'd be good to see what is actually happening vs "it is not booting, cause I can't tell whats going on"

[gotan09]

Hello Warhead,
thank you for your reply . I don not have a serial hook up to the device.

After first boot up the following start console appears:

ARCH LINUX 3.3.90-2-ARCH (tty1)
alarm login:

Then, it does not matter wether I login in with username/passwd root/root and then do something and shutdown or logout and power down with PowerKey or after first boot up I immediatley power down the cubieboard with the PowerKey again, the result is always the same: after the next boot up the display stays black and no information is displayed and only the red power on LED glows. That's why I can not give any further information to you.

I partitioned the sd-card with fdisk /dev/sda . The first partition is a 32MB FAT32 and starts with 2048, the second partition is ext4.
I formatted the FAT32 with mkfs.vfat -F 32 /dev/sda1 and it was answerd with WARNING: Not enough clusters for a 32 bit FAT! . After that, I tried a 50MB FAT32 and it worked. I formatted the ext4 with mkfs.ext /dev/sda .

The fdisk menu point v brings out the messages:

Partition 1: previous sectors 104447 disagrees withe total 105684
Partitions 2: cylinder 1018 greater than maximum 1017
Partition 2: previous sectors 7882751 disagrees with total 7882891
Remaining 2047 unallocated 512-byte sectors

[gotan09]

Hello WarheadsSE,

I'm sorry, I did a mistake. The correct tarball identifier is: 3.4.90-2-ARCH.

[WarheadsSE]

I would suggest just not using 32bit fat.

[gotan09]

Hello WarheadsSE,

now, I used for the first partition a 32MB FAT16, but the result is the same.

[gotan09]

Hello WarheadsSE,

I connected my Cubieboard to a serial link and saved the system messages in a text-file with extension .txt. But files with this extension are not allowed for uploading. What extensions are allowed for uploading?

[gotan09]

Hello WarheadsSE,

I would rather send you the complete system message file but at least for now an excerpt of the system messages during the second booting: Inside the system messages I found the subsequent message:

Hello WarheadsSE,

I tried the following command from the hypertermal:

$this->bbcode_second_pass_code('', '[root@alarm ~]# systemctl status systemd-modules-load.service
* systemd-modules-load.service - Load Kernel Modules
Loaded: loaded (/usr/lib/systemd/system/systemd-modules-load.service; static)
Active: failed (Result: signal) since Fri 2010-01-01 01:23:20 UTC; 4 years 7 months ago
Docs: man:systemd-modules-load.service(8)
man:modules-load.d(5)
Process: 75 ExecStart=/usr/lib/systemd/systemd-modules-load (code=killed, signal=SEGV)

[root@alarm ~]#
')

Then fired this command:

$this->bbcode_second_pass_code('', '[root@alarm ~]# systemctl start systemd-modules-load.service
[ 274.879111] Console: switching to colour frame buffer device 160x64

[ 274.919578] Registered led device: green:ph20:led1
[ 274.925796] Registered led device: blue:ph21:led2
[root@alarm ~]#
')

After that the the dispaly which is attached to my cubieboard showed the expected console with the request to login and the green led was glowing. Then I shutdown the cubieboard again and booted up again with the already descripted behaviour: the display stays dark as well as the green led.

Then I tried the following command:

$this->bbcode_second_pass_code('', '[root@alarm ~]# systemctl enable systemd-modules-load.service
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
[root@alarm ~]#
')

What is the problem of all?
