U-Boot 2015 http://www.igorpecovnik.com/2015/02/20/udoo-quad-debian-sd-image/
Download the software:
wget http://mirror.igorpecovnik.com/kernel/4.0.8-udoo-next.tar
extract it and only install the u-boot package:
dpkg -i linux-u-boot-4.0.8-udoo_1.8_armhf.deb
Kernel based on https://github.com/patrykk/linux-udoo
Install prerequisites:
apt-get install lzop kernel-package u-boot-tools dblatex docbook-utils \ kernel-common libsgmls-perl libsp1c2 libtinfo-dev sgmlspl sp texlive \ texlive-bibtex-extra texlive-math-extra xmlto xsltproc libncurses5-dev
Getting the kernel:
cd /tmp
mkdir kernel4.0.8
cd kernel4.0.8
wget https://github.com/patrykk/linux-udoo/archive/4.0.8.zip
unzip 4.0.8.zip
now change directory to the kernel folder and configure it:
make menuconfig
compile it – in my case it took approx 2 hours:
make uImage LOADADDR=0x10008000 modulesinstall the modules:
make modules_installcopy the kernel to /boot folder
cp arch/arm/boot/uImage /boot/
cp arch/arm/boot/zImage /boot/
compile the dtb file:
make imx6q-udoo.dtbcopy dtb file
cp arch/arm/boot/dts/imx6q-udoo.dtb /boot/dts/
copy firmware
cp firmware/imx/sdma/sdma-imx6q.bin /lib/firmware/sdma/
configure your uboot
nano /boot/boot.cmd
then copy and paste this
setenv bootargs root=/dev/mmcblk0p1 rootfstype=ext4 rootwait console=ttymxc1,115200
ext2load mmc 0 0x18000000 /boot/dtb/imx6q-udoo.dtb
ext2load mmc 0 0x12000000 /boot/zImage
bootz 0x12000000 - 0x18000000
if you use graphical interface you will probably want to replace the first line with:
setenv bootargs root=/dev/mmcblk0p1 rootfstype=ext4 rootwait console=tty1 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 ahci_imx.hotplug=1 quiet
then convert it to uboot format
mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
Now cross fingers, connect console cable and restart the device
