Accessories / Simple cubieboard case for 2.5" HDD
October 06, 2014, 04:56:07 am
Hallo,
It may be useful for somebody. I have made following case for my cubiaboard.
I send plans as .dxf file to Advertising Company which cut and bend 2mm thick plexiglass.
To combine board with the case i use plastic L shape profile bought in castorama.
Summary costs ~6$
The .dxf file shows top of the case. I decide to leave base open to easy attach shields.

I don't know if you also think about it but it would be nice to provide repo for packages for cubie.. e.g. XBMC binariesor additional libs for IO programming like python-spi tested and
avilable from apt-get..

I have had problems with wifi dongle base on realtek RTL8191SU. It use r8712u module which was missing. Compiling single module (by cross compiler & natively) provide:
ERROR: could not insert 'r8712u': Exec format error

Recompilation whole kernel helps.

---kernel compile in my way  ;):
#apt-get install gcc-arm-linux-gnueabihf build-essential git uboot-mkimage libncurses5-dev
---not need changes history.. (git clone)
#wget https://github.com/mmplayer/linux-sunxi/archive/sunxi-3.4.zip
#cd linux-sunxi-sunxi-3.4
---gets current config  (backup old if exist)
#mv .config .config-old
#scripts/extract-ikconfig /boot/uImage >.config
#make ARCH=arm menuconfig
---modify configuration

What I see (menuconfig) that default sunxi kernel config used in cubian r3 does not fit to our board. I expect that kernel will be better optimized smaller and faster.

I will try to better optimalization on my own (maybe this will be good start point: https://www.miniand.com/forums/forums/development--5/topics/linaro-ubuntu-custom-server-images-armhf - this kernel waight less)

Another step will be CedarX and Xbmc tests with cubian. Already test it with few images http://linux-sunxi.org/More-images and even create own.. unfortunatly mali400 drivers (even CedarX) does not play good - to compare see XBMC on android.

What is nice that we finally get distribution dedicated to our board.

Than you Cubieplayer
