Accessories / Simple cubieboard case for 2.5" HDD
October 06, 2014, 04:56:07 am
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 upgrade cubie_config from Cubieez.
I add nand install option from cubian.
It should work fine for all systems from sd card,758.0.html

Hallo base on cubieez(drkbcn) modification of rpi_config and script I have create cubie_config with easy nand install option.
You can get it from:
should work for any sd image uImage nad script.bin is get from /boot dir

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..

found more:

export CFLAGS="-mthumb -march=armv7-a"

& kernel config option
Kernel Features --->
  (*) Compilethe kernel in Thumb-2 mode [CONFIG_THUMB2_KERNEL=y]
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 base description:

---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)
#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
Removing some unnecessary modules eg. strange partition types support

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: - this kernel waight less)

Another step will be CedarX and Xbmc tests with cubian. Already test it with few 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
