OK, some quick tips:

v3.7 jessie image is broken due to some systemd changes. I saw too late. 3.8 is boots ok - at least with network attached. I haven't tested without for a while. On new kernel there is no output to serial console by default.

loading with

bcmdhd op_mode=2

works with wheezy and trusty but not jessie

4.0.4 different module

brcmfmac. It should work ... I haven't tested with 4.0.4 but with 3.19.x and it was working w/o problems.

If you want a proven configuration, stick to Wheezy with kernel 3.4.x

Video resolution. I'll go down with default one or made some other solution.

Waiting for 3min might not be enough. I am doing apt-get update at first boot.

My images are not designed to be installed directly to NAND because in this case they must be prepared in some Allwinner specific / nonstandard way. A complete waste of time from my perspective.

Yes, there is another way. Create a SD card, plug it into Cubie, power on and wait for one automatic restart. Login as root and run my "Sata NAND install tool" which resist in /root directory. Simply follow the guide.

Use image with kernel 3.4.10x which is the only one that supports NAND. At the moment.

Cubieboard 4 / Allwinner A80 is in general poorly supported. By manufacturer and community. There is only one old development kernel source (from Android?) to work with and some basic support in mainline kernel.

My progress with CB4 is minor so can't support.

For now.

The best what I saw on CB4 is this image:

Nice. I'll take a look later on .. .but if you succeed in compilation just push up to Github the working compilation.

BTW: you can now switch to kernel 4.0.4, patches are fixed, kernel boots fine.

KERNELTAG="v4.0.4" # kernel TAG - valid only for mainline

On console or via SSH?

If it's enabled than you can do with:

cat /proc/config.gz | gunzip > running.config

And if I want to build an image that uses a different default password, where would I change the default 1234?

Main call /configuration script ?

ROOTPWD="1234"                              # forced to change @first login

For the headers I need this is an example output of success on Minibian (uses Raspbian kernel AFAIK)

Dump it's kernel configuration if possible.

This works for both kernels or only on new one?

I have to get one. Any better option than this:

May 25, 2015

Oh, true. Thanks!

:beer:

H3 should perform better than A20 when it get's a decent kernel support.

May 25, 2015

Yes. Jessie & systemd are causing some additional troubles and this is one of them.

It started in latest build - the build before Jessie was anyway completely broken.

You simply need to wait that it reboots than it works just fine.

I know it's not noted under bugs. I'll add. Thanks for bringing up.

This will keep the password which you set at first login.

If you want to force users to change (root) password in next login use:

chage -d 0 root

There is also an option to use my script for generating a custom distribution.

I am using one parameter for this:

AFTERINSTALL=""                             # command before closing image

So if you put everything in one script you run this script here or just download additional packages with apt-get ...

In this case you will have the same startup procedure as mine - same root pwd, shrunk install image, auto expand, ...

Script firstrun /etc/inid.d/firstrun

To re-enable it:

 update-rc.d firstrun defaults

PMP is not enabled by default in any image and there is no modular solution yet. I was not working anything in this field yet.

You need to hack and recompile kernel - a quick summary for those who don't know how:

nano drivers/ata/sw_ahci_platform.c

Change from:

.private_data = (void*)(AHCI_HFLAG_32BIT_ONLY | AHCI_HFLAG_NO_MSI
             | AHCI_HFLAG_NO_PMP | AHCI_HFLAG_YES_NCQ),
};

to:

.private_data = (void*)(AHCI_HFLAG_32BIT_ONLY | AHCI_HFLAG_NO_MSI
             | AHCI_HFLAG_YES_NCQ),
};

Recompile kernel.

Do any of your images have dvb header support like Raspbian?

There is a lot of stuff in both kernels and I keep adding. What exactly do you miss?

Aha, that's U-boot patch which helps if you boot from SATA.

No, it's not in older images. Install this Uboot:

http://mirror.igorpecovnik.com/u-boot/linux-u-boot-3.4.107-lamobo-r1_3.0_armhf.deb

May 25, 2015

You mean this?

https://github.com/igorpecovnik/lib/blob/next/config/lamobo-r1.fex#L697

[sata_para]
sata_used = 1
sata_power_en = port:PB03<1><default><default><0>

I haven't notice such problems. All I know regarding SATA is it's proper powering - that's patch about. Is there any other solution? Once it's powered it works. I am having a rotating hard drive on it and it's working fine ... if I don't use HDMI and/or USB :huh:

Powering is in general problem with this board but thanks to poor board design. There is little we can do with software.

I hope adding this is enough?

https://github.com/igorpecovnik/lib/commit/3fb1e9f94b0366f77366dc4bc310978395e6eee2

Try to re-compile kernel by yourself, I won't be rebuilding soon.

Wheezy:

deb http://repo.jm0.eu/BSP:/Cubox-i/Debian_Wheezy/ ./

Repository is online but installations is untested by me.

May 23, 2015

Not now. There was a recent discussion among comments that it actually doesn't bring any significant improvement. Yet.

May 23, 2015

:huh: Not sure.

What I am sure is that "testing" / "beta" or similar is to avoid.

May 23, 2015

Thanks! :rolleyes:

I'll add the SSL in the next forum enhancement streak

BTW. I also added Tapatalk so the board is more tablet / mobile friendly.

May 23, 2015

From testing repository ... which was there by mistake. I used to focus mostly on Wheezy and nobody else noticed for a while as well

Tagging problem become and issue when Jessie becomes stable. I fixed this about two weeks ago & images compiled two days ago (v3.8) are o.k. regarding this.

Wheezy = "oldstable" and Jessie = "stable"

I changed tagging to names now.

Cubietruck has one exception and only with kernel 3.4.x - wifi module must be loaded (/etc/modules) this way to enable AP mode:

bcmdhd op_mode=2

I suggest you to use this predefined configuration - which you probably already set.

/etc/network/interfaces.hostapd

You need to have some DHCP server running on the network - which usually is.

Thanks

I open an H3 thread in forum Development and add how far I got. Not much.

The idea is that H3 goes to the general Allwinner section when it looses development status. I only booted manufacturer Debian server and it's horrible, unusable.
