Debian Wheezy Debootstrap

A VERY ROUGH SET OF INSTRUCTIONS, RUN WITH CARE

See https://github.com/qbcode/novena-baseimage

This set of instructions assumes you have a functioning Novena board with Debian Wheezy. These instructions are primarily for people who want to re-create the firmware/base image. It relies on various bits and pieces of information on this wiki.

Prerequisites

  • An existing Novena board running Debian Wheezy .
  • Root access on your board, ideally have sudo access with no password.
  • A 4gb microsd card.
  • A reasonably fast network connection.
  • Approximately 10gigs of free diskspace (more is probably better so you can cache things during testing/dev) - ideally get a SSD plugged into the board.
  • Assumes 'you as a user' has tried building a linux kernel, u-boot etc...
    • i.e. we assume you have generated the kernel debian packages, uImage, uImage.dtb, the relevant boot loader and boot scripts.

Summary

Steps

Be logged in as yourself.

Install at least these things... 

sudo apt-get install -y qemu-utils apt-cacher-ng build-essential less rsync lzop u-boot-tools git debhelper bc device-tree-compiler parted

Generate a new boot script... 

mkimage -A arm -O linux -a 0 -e 0 -T script -C none -n "Boot script" -d boot.script boot.scr

Where boot.script contains this... 

mmc dev 1
if fatload mmc 1 0x12000000 uImage
then
	fatload mmc 1 0x11ff0000 uImage.dtb
	setenv bootargs console=${console},${baudrate} root=${mmcroot}
	setenv bootargs console=ttymxc1,115200 earlyprintk root=/dev/mmcblk1p2 rootwait rootfstype=ext4 splash consoleblank=0
else
	mmc dev 0
	fatload mmc 0 0x12000000 uImage
	fatload mmc 0 0x11ff0000 uImage.dtb
	setenv bootargs console=ttymxc1,115200 earlyprintk root=/dev/mmcblk0p2 rootwait rootfstype=ext4 splash consoleblank=0
fi

fdt addr 0x11ff0000; run prep_gbit; run prep_pcie; run prep_senoko; run prep_es8328; run prep_retina; run prep_pixelqi; run prep_hdmi

bootm 0x12000000 - 0x11ff0000

Generate the boot loader 

git clone https://github.com/sutajiokousagi/u-boot-imx6.git
cd u-boot-imx6 && make novena_config && make

Generate the kernel image 

git clone https://github.com/xobs/novena-linux.git
cd novena-linux && git checkout v3.16-rc2-novena && make novena_defconfig && make uImage LOADADDR=10008000 -j 4 && make ARCH=arm imx6q-novena.dtb

Generate the kernel debian packages with this shell script (run this in the novena-linux repo on the right branch) 

#!/bin/sh
make -j4 \
	LOADADDR=0x10008000 \
	LD=gold \

	KBUILD_IMAGE=uImage \
	KBUILD_DTB=imx6q-novena.dtb \
	KDEB_PKGVERSION=1.2 \
