Getting Genode with TrustZone on the i.MX53 Quick Start Board
Posted February 21, 2015 by Peter Teoh in genode, i.MX53SQB. 5 Comments
First download the toolchain for ARM compilation, and then the Genode OS itself, all listed here:
http://sourceforge.net/projects/genode/files/
Details description of Genode and its installation are found here:
http://genode.org/documentation/developer-resources/getting_started
http://genode.org/documentation/release-notes/14.11
https://github.com/genodelabs/genode/blob/master/doc/getting_started.txt
Install all the necessary packages for Ubuntu 14.04 (present host):
apt-get install libSDL-dev
apt-get install libsdl1.2-dev -> shows it is already newest version
apt-get install tk8.5 tcl8.5
apt-get install expect
apt-get install byacc
apt-get install qemu
apt-get install genisoimage
sudo apt-get install expect
sudo apt-get install udisks
After untarring the genode toolchain /usr/local/genode-gcc directory, next is to untar the Genode OS download to “genode-14.11″.
With some assistance as documented here:
http://sourceforge.net/p/genode/mailman/message/33465225/
cd genode-14.11/
cd tool/Listing all the hardware:
./create_builddir
‘linux_x86′
‘linux_arm’
‘fiasco_x86′
‘pistachio_x86′
‘okl4_x86′
‘nova_x86_32′
‘nova_x86_64′
‘codezero_vpb926′
‘hw_panda’
‘hw_vea9x4′
‘hw_vea9x4_tz’
‘hw_pbxa9′
‘hw_imx31′
‘hw_imx53′
‘hw_imx53_tz’
‘hw_arndale’
‘hw_odroid_xu’
‘hw_rpi’
‘foc_x86_32′
‘foc_x86_64′
‘foc_pbxa9′
‘foc_imx53′
‘foc_vea9x4′
‘foc_panda’
‘foc_arndale’
‘lx_hybrid_x86′
Now we set the hardware to be imx53:
./create_builddir hw_imx53_tz BUILD_DIR=build_imx53
cd build_imx53/
Setting up it for uboot as the bootloader:
echo "SPECS += trustzone" >> etc/specs.confecho "RUN_OPT = --target uboot" >> etc/build.confmake run/tz_vmm
After this “uImage” is generated in the build_imx53/var/run.
Now, to download u-boot bootloader (and its ARM gcc compiler):
git clone https://github.com/m-stein/uboot uboot_stein
cd uboot_stein/
wget http://releases.linaro.org/14.09/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.9-2014.09_linux.tar.xz
Extract out the config file:
make ARCH=arm CROSS_COMPILE=/opt/gcc-linaro-arm-none-eabi-4.9-2014.09_linux/bin/arm-none-eabi- usbarmory_config
Now start the make process:
make ARCH=arm CROSS_COMPILE=/opt/gcc-linaro-arm-none-eabi-4.9-2014.09_linux/bin/arm-none-eabi- V=1
Notice a “u-boot.imx” is created. But first we need to format the sdcard.
(from hence onwards my sdcard is detected as /dev/sdg???):
Aim: make a sdcard from uImage, which will require uboot bootloader:
sudo parted /dev/sdg –script mklabel msdos
sudo parted /dev/sdg –script mkpart primary ext4 5M 100%
Upon completion, “dd” the u-boot.imx (which is meant for imx53 as the target) to the sdcard’s 3rd 512-block:
sudo dd if=./u-boot.imx of=/dev/sdg seek=2 bs=512 conv=fsync
Take a look at the partition:
sudo fdisk -l /dev/sdg
sudo mkfs.ext4 /dev/sdg1
Now /dev/sdg1 is ext4-formatted, mount it:
udisks –mount /dev/sdg1
Copy the uImage there to the rootfs:
cp uImage /media/371a8dd7-58c1-4beb-aed3-cb18fb40f7eb/
And umount it:
sudo udisks –umount /dev/sdg1
Now insert the sdcard into i.MX53QSB and connect via serial port, bootup message as follows:
