I have tested Armbian with mainline kernel on A10-OLinuxino-Lime-4G board. The only one change is :

diff --git a/configuration.sh b/configuration.sh

 REVISION="1.9"
-BOOTCONFIG="A20-OLinuXino-Lime_defconfig"
+BOOTCONFIG="A10-OLinuXino-Lime_defconfig"
 MODULES="hci_uart gpio_sunxi rfcomm hidp bonding spi_sun7i 8021q a20_tp"
 MODULES_NEXT=""
 ;;

After this patch correct version of U-boot (.config file) is build and correct dtb-file is used at boot.

 

It can't be committed "as is" because this patch removes support of A20-OLinuXino-Lime. So some refactoring of $BOARDS in main.sh is needed to support A10-OLinuXino-Lime, A20-OLinuXino-Lime and A20-OLinuXino-Lime2 boards. Dear Igor! Please, add support of this boards to Armbian!

 

Best regards,

    Yuri

1) Lime A10 image with kernel 4.1.2


Boots OK. Serial and HDMI consoles work.

Only one error during first boot: "/etc/init.d/armhwinfo: line 51: echo: write error: Input/output error". I think it is due to only one core in A10.

Do you need dmesg or /var/log/* files?

2) Lime A10 image with kernel 3.4.108 and HW accelerated MATE desktop

It starts boot, but it hangs. Output from serial console is below:

And to you previous question: no, I don't check kernel 3.4.x before.

Thanks.

 

1. I don't need logs. You are right ... I'll fix asap.

2. No ideas at this point. I guess it's not a proper FEX script. I use the one from here.

Access to hardware would be nice to conduct more tests. It would be glad to have this working ... some day ;)

This one initialises DRAM with 480 MHz which according to Olimex (when they released the A20 Lime2 they talked about "much better routing of DDR3 memory" and what's said regarding A20-Lime should apply to the A10-Lime as well) might not work reliable.

 

@Yuri: Can you try to have a look what Olimex sets in the script.bin they use with their own images? Might be 384 MHz instead.

 

BTW: Using A10 together with HW accelerated desktop (or desktop at all) is no good idea: http://linux-sunxi.org/Optimizing_system_performance#Using_a_lower_resolution_graphics_mode

I looked through kernel config files and found than in config for Lime A10 image with kernel 3.4.108 and HW accelerated MATE desktop there are:

# CONFIG_ARCH_SUN4I is not set
# CONFIG_ARCH_SUN5I is not set
CONFIG_ARCH_SUN7I=y

It is not good... Config file is here.

Result is the same.

It seems that in 3.4 kernel it is impossible to have both CONFIG_ARCH_SUN4I=y and CONFIG_ARCH_SUN7I=y. In last image only CONFIG_ARCH_SUN7I is set.

Now I am compiling 3.4 kernel with only CONFIG_ARCH_SUN4I=y.

Hm. Only now I have found than I can't build linux-sunxi-3.4 kernel (with Lime-A20 and Lime2-A20 config file). Something wrong with return_address function, but right now I can't correct it.

init/do_mounts_rd.o: In function `return_address':

I am working on Ubuntu 14.04 with it's defaults.

 

Hmm... I thought installing Linaro's standalone cross-compiler toolchain is recommended? I use

 

http://releases.linaro.org/14.11/components/toolchain/binaries/arm-linux-gnueabihf/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf.tar.xz

 

and unpacked it in /usr/local and define 

export PATH="/usr/local/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf/bin/:$PATH"

@Yuri: Since you're using an A10 I would love to get feedback regarding reading out thermal values from its TP's thermal sensor inside. Please have a look at this thread. Would be great if you could unpack the sunxi-monitor.tar.gz archive and provide the output of

/usr/share/rpimonitor/scripts/sunxi_tp_temp 1447

to get a clue whether this approachs works on A10/A13 as well. Thx (and sorry for thread hijacking)

tkaiser! 

root@lime-a10:~/sunxi-monitor/usr/share/rpimonitor/scripts# ./sunxi_tp_temp 1447
78.8
root@lime-a10:~/sunxi-monitor/usr/share/rpimonitor/scripts# ./sunxi_tp_temp 1447
79.0

P.S. I use mainline (4.1.1) kernel.

Hello

 

I bought Olimex A10Lime two weeks ago. Since I have no prior UNIX/Linux experience I have just booted it with official Olimex's Debian image* with wheezy on it. It has EGLIBC with 2.13 and GCC with 4.6.

 
 
The main reason why I bought this card was to learn embedded Linux while developing some applications over it with Qt Framework.
 
But I am struggling to cross compile Qt for it. Firstly, I have noticed that if I use cross toolchain with different version of C libraries than those on my target OS, it fails linking and stops compilation.
 
But because GCC-4.6 has no C++11 support I wouldn't  like to actually use a crosstoolchain with it. So I have tried to upgrade my EGLIBC and GCC on my target OS. But I found some comments on the internet saying that upgrading EGLIBC wouldn't be the safe way. So I tried to transit from wheezy to jessie using the same image. But it has failed because of a package(which is udev) that is not compatible with the kernel on my target OS. 
 
After those tries I tried to use Debian installer like explained on this link,
 
But because of the u-boot that Debian provides, the system was headless which can not be the case for my purpose. 
 
I researched Ubuntu trusty or Debian jessie is the completely perfect environment for me. those have GCC with 4.8 and EGLIBC with 2.19. And those are also stable as well..
 
My question is; do you have any advice for me to accomplish my purpose on Olimex A10 Lime? I don't mind if there aren't any X desktops on my target OS but I know that I would need OpenGL ES 2 support on it to use EGL on Qt.
 
Thank you,
Sina

Ah!!

 

Finally I have an environment with gcc 4.9!

 

Thanks for your efforts. I have used that image http://mirror.igorpecovnik.com/Lime-a10_Debian_1.0_wheezy_4.1.2.zip and followed Igor's FAQ* about upgrading from wheezy to jessie.. Thats it :)

 

* http://www.igorpecovnik.com/2014/11/18/olimex-lime-debian-sd-image/

 

How to upgrade from Debian Wheezy to Debian Jessie?

dpkg -r ramlog 
cp /etc/apt/sources.list{,.bak}
sed -i -e 's/ \(stable\|wheezy\)/ jessie/ig' /etc/apt/sources.list
apt-get update
apt-get --download-only dist-upgrade

apt-get dist-upgrade

 

After I just checked my release info, lsb_release -a it is jessie :)

 

But now I have another problem with it. I guess that kernel-4.1.2 is linux-kernel, which is not sunxi-kernel. So it does not have the Mali Binary Libraries. So is it possible to install this driver on that kernel? I need Mali for Opengl ES 2 support. Also is it possible to have LCD support on that system?

 

Btw is there any recomendations for cross compiler?

 

Thank you,

Sina
