8. Preparing the images to run on Juno
---------------------------------------
### Preparing Trusted Firmware images
The Juno platform requires a BL3-0 image to boot up. This image contains the
runtime firmware that runs on the SCP (System Control Processor). It can be
downloaded from the [ARM Silver SCP website] (requires registration).
Rebuild the Trusted Firmware specifying the BL3-0 image. Refer to the section
"Building the Trusted Firmware". Alternatively, the FIP image can be updated
manually with the BL3-0 image:
fip_create --dump --bl30 <path-to>/<bl30-binary> <path-to>/<FIP-binary>
### Obtaining the Flattened Device Tree
Juno's device tree blob is built along with the kernel. It is located in:
<path-to-linux>/arch/arm64/boot/dts/juno.dtb
### Deploying a root filesystem on a USB mass storage device
1. Format the partition on the USB mass storage as ext4 filesystem.
A 2GB or larger USB mass storage device is required. If another filesystem
type is preferred then support needs to be enabled in the kernel. For
example, if the USB mass storage corresponds to /dev/sdb device on your
computer, use the following command to format partition 1 as ext4:
sudo mkfs.ext4 /dev/sdb1
Note: Please be cautious with this command as it could format your hard
drive instead if you specify the wrong device.
2. Mount the USB mass storage on the computer (if not done automatically):
sudo mount /dev/sdb1 /media/usb_storage
where '/media/usb_storage' corresponds to the mount point (the directory
must exist prior to using the mount command).
3. Download the rootfs specified in section "Prepare RAM-disk" and extract the
files as root user onto the formatted partition:
sudo tar zxf <linaro-image>.tar.gz -C /media/usb_storage/
Note: It is not necessary to modify the Linaro image as described in that
section since we are not using a RAM-disk.
5. Unmount the USB mass storage:
sudo umount /media/usb_storage
9. Running the software on Juno
--------------------------------
The steps to install and run the binaries on Juno are as follows:
1. Connect a serial cable to the UART0 port (the top UART port on the back
panel). The UART settings are 115200 bauds, 8 bits data, no parity, 1 stop
bit.
2. Mount the Juno board storage via the CONFIG USB port
This is the only USB type B port on the board, labelled DBG_USB and located
on the back panel next to the ON/OFF and HW RESET buttons. Plug a type B USB
cable into this port on the Juno board and plug the other end into a host
PC, and then issue the following command in the UART0 session:
Cmd> usb_on
If the board doesn't show the Cmd> prompt then press the black HW RESET
button once. Once the Juno board storage is detected by your PC, mount it
(if not automatically done by your operating system).
mount /dev/sdbX /media/JUNO
For the rest of the installation instructions, we will assume that the Juno
board storage has been mounted under the /media/JUNO directory.
3. Copy the files obtained from the build process into /media/JUNO/SOFTWARE:
bl1.bin
fip.bin
Image
juno.dtb
4. Umount the Juno board storage
umount /media/JUNO
5. Reboot the board. In the UART0 session, type:
Cmd> reboot
