playing around with my udoo quad on my sick weekend

ala http://kencochrane.net/blog/2013/05/running-docker-on-a-raspberrypi/

   apt-get install git

darn;

grabbing source on another computer and scping it over.

$ apt-get install ncurses-dev

mmm, ok, so thats a 3.0.35 ancient thing

lets go get 

root@imx6-qsdl:/data# git clone --depth 1 git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stab
le.git

and see what happens

#probably just brings in things that are not needed
apt-get install kernel-package

#3.11 needs 'bc'
apt-get install bc

mmm, apt-get install kexec didn't help, trying the bleed version from
 git://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git 

mmm, need
apt-get install u-boot-tools

mmm, need

so i can
make uImage

aha, there's a dtbs commited recently to the arm tree, so I'll have to go clone a whole new kernel tree
http://permalink.gmane.org/gmane.linux.ports.arm.kernel/269270
http://u-boot.10912.n7.nabble.com/PATCH-udoo-Add-initial-support-for-mx6q-udoo-board-td164161.html

so trying 
git clone https://git.linaro.org/gitweb?p=people/shawnguo/linux-2.6.git;a=summary

AAAARGH
I need the dtc compiler - see http://xillybus.com/tutorials/device-tree-zynq-1
git clone git://www.jdl.com/software/dtc.git dtc

for which i need flex&bison

apt-get install flex bison

make dtc
ln -s /data/dtc/dtc scripts/dtc/dtc (in the linux kernel dir...)

root@imx6-qsdl:/data/linaro-shawnguo (for-next)# make imx6q-udoo.dtb
  DTC     arch/arm/boot/dts/imx6q-udoo.dtb


AAARGH again!

(for-next)# /usr/local/sbin/kexec --dtb arch/arm/boot/dts/imx6q-udoo.dt  -l arch/arm/boot/uImage -append="root=/dev/mmcblk0p1  mem=768M arm_freq=996"
imx6q-udoo.dtb  imx6q-udoo.dts  
root@imx6-qsdl:/data/linaro-shawnguo (for-next)# /usr/local/sbin/kexec --dtb arch/arm/boot/dts/imx6q-udoo.dtb  -l arch/arm/boot/uImage -append="root=/dev/mmcb
lk0p1  mem=768M arm_freq=996"
DTB too large!
Cannot load arch/arm/boot/uImage


ok, so maybe i have to work out how to build the dtc in the kernel source?

oooo, http://www.cadence.com/Community/blogs/sd/archive/2013/10/09/combining-the-linux-device-tree-and-kernel-image-for-arm.aspx?utm_source=feedburner&utm_med
ium=feed&utm_campaign=Feed:+cadence/community/blogs/sd+%28Cadence+System+Design+and+Verification+Blogs%29&sf18256790=1
maybe i can just use that to append the dts?


---------------------
TODO:

1. set up a PXE boot docker image (mmm, so dhcp, dns, tftp, just need to cfg and go?)
2. or not - build something similar that uses kexec.. http://www.ibm.com/developerworks/linux/library/l-kexec/index.html
