Unpack the compressed image file.
For FVP copy the image to the root directory of your workspace.
For Juno or TC2 insert a USB stick (minimum 4GB) into your system and run:
bc. sudo dd if=<downloaded file>.img of=/dev/sd<x>
(where @<x>@ is the letter corresponding to the USB stick)
For Juno Android, download "ramdisk.img":https://releases.linaro.org/15.06/android/reference-lcr/juno/ramdisk.img or
for FVP Android, download "ramdisk.img":https://releases.linaro.org/15.06/android/reference-lcr/fvp/ramdisk.img or
for TC2 Android, download "ramdisk.img":https://releases.linaro.org/15.06/android/reference-lcr/vexpress-tc2/ramdisk.img
and copy to the root directory of your workspace.
h3(#build). 2.4 Building the software
* First decide how you wish to specify your cross compiler:
** Add the @CROSS_COMPILE=<path-and-prefix>@ prefix to all build script invocations.
** Edit @<workspace>/build-scripts/variants@ files to make CROSS_COMPILE point at the path and prefix to where you installed Linaro GCC.
** note: you may specify the prefix without a path if the compiler is on your path.
* Next, choose the setup from the tables below and copy the variables into your shell before executing the "Commands to run":
h4. Choose your platform
| *Platform* | *Variable* |
| Juno ARM Development Platform | @PLATFORM=juno@ |
| FVP Foundation or AEMv8 models | @PLATFORM=fvp@ |
| Versatile Express TC2 | @PLATFORM=tc2@ |
h4. Choose your manifest
| *Kernel Version* | *Variable* |
| LSK | @MANIFEST=lsk@ |
| Latest Tracking Kernel | @MANIFEST=latest@ |
h4. Choose your environment type
| *Environment* | *Variable* |
| Android | @TYPE=android@ |
| BusyBox | @TYPE=busybox@ |
| OpenEmbedded | @TYPE=oe@ |
h4. Commands to run
Once you have configured the variables in your shell, run these commands from the root directory of your workspace to build the software components and package them into an output folder:
bc. repo init -u https://git.linaro.org/landing-teams/working/arm/manifest -b 15.08 -m pinned-${MANIFEST}.xml
repo sync -j8
./build-scripts/build-all.sh ${PLATFORM}-${TYPE}
./build-scripts/build-all.sh ${PLATFORM}-${TYPE} package
The build will create binaries for ARM Trusted Firmware, UEFI, U-Boot, Linux, ramdisk and a DTB where appropriate. For Aarch64 platforms, the Firmware components will then be packaged into a FIP. All the binaries copied under the "output" folder.
Running a different build will overwrite derived objects in the source tree, but will not overwrite the output folder created by the package step.
h3(#install). 2.5 Installing on your Juno or TC2
* Mount the board's flash device
Connect up the USB configuration port to your build system whereby the MMC which populates the NOR flash at boot will be mounted as a new drive.
* Ensure your system binaries are up to date
For Juno, take the system binaries from the recovery folder from your workspace
For TC2, take the system binaries from the vexpress-firmware folder from your workspace
For both Juno and TC2, delete all the files on the mounted drive and copy over all of @SOFTWARE@, @SITE1@, @MB@ and @config.txt@.
* Copy the binaries you have built to your board
For UEFI copy the contents of @output/<variant>/uefi@ to the SOFTWARE folder
For U-Boot copy the contents of @output/<variant>/uboot@ to the SOFTWARE folder
Where @<variant>@ is the argument to build-all.sh above - eg: juno-android or tc2-android
* For Android or OpenEmbedded Insert the USB stick created above into your board (not needed for BusyBox)
Power cycle your board and it will copy and run the new software images.
h3(#fvp). 2.6 Running the FVP
To run the FVP models, you must first set the following variables:
| *Variable* | *Usage* | *Example* |
| $MODEL | This sets the path and filename of the model executable | /usr/local/FVP_Base_AEMv8A-AEMv8A |
| $DISK | This sets the path and filename of the disk image. Busybox variants don't need to set DISK, however both OE and Android variants will fail to boot without it. You should download and unzip the disk image before running the model. | $USER/Downloads/fvp.img |
Then, from your workspace root directory, you launch the model, telling it the path of the variant you wish to boot.
First set the model variable
bc. export MODEL=/usr/local/FVP_Base_AEMv8A-AEMv8A
Example 1: Running a busybox uboot variant:
bc. ./model-scripts/run_model.sh output/fvp-busybox/uboot
Example 2: Running an Android uboot variant:
bc. export DISK=fvp.img
./model-scripts/run_model.sh output/fvp-android/uboot
Example 3: Running an OpenEmbedded UEFI variant:
bc. export DISK=lt-vexpress64-openembedded_minimal-armv8-gcc-4.9_20150620-722.img
./model-scripts/run_model.sh output/fvp-oe/uefi
h3(#prebuilt). 2.7 Using prebuilt binaries
If you want to use prebuilt firmware and kernel binaries rather than download and build the software as described above, first, you should follow the instructions in "section 2.3":#down-bins and then download the prebuilt firmware images for the platform you wish to use.
The pre-built ZIPs contain the files for each supported configuration. For Juno the contents should be copied to the
root of the mounted drive as per the recovery image in section 2.5. For FVP the contents should be copied to your workspace output folder (which you will need to create if you have not run a build). For TC2, the files should be copied to the SOFTWARE folder of the mounted drive as per the vexpress-firmware image in section 2.7.
Other variants are only available when built from source. The current prebuilt binaries are targeted at Mobile, Enterprise and developer segments.
h4. Juno Prebuilt Binaries
Prebuilt binaries are available by following the links in the table below. These binaries contain the Juno recovery images and so can be used to restore a broken system.
