| ARM Juno r1/r0 |
| |
| Intro |
| ===== |
| |
| These instructions apply to all models of the ARM Juno: |
| - Juno r0 (does not support PCIe) |
| - Juno r1 (supports PCIe) |
| - Juno r2 (Big Cluster with A72) |
| |
| Buildroot will generate the kernel image, device tree blob, bootloader binaries |
| and a minimal root filesystem. |
| |
| How to build it |
| =============== |
| |
| Configure Buildroot |
| ------------------- |
| |
| Configuring Buildroot is pretty simple, just execute: |
| |
| $ make arm_juno_defconfig |
| |
| Build the rootfs, kernel and DTB |
| -------------------------------- |
| |
| Note: you will need to have access to the network, since Buildroot will |
| download the packages' sources. |
| |
| You may now build your rootfs with: |
| |
| $ make |
| |
| (This may take a while) |
| |
| Result of the build |
| ------------------- |
| |
| After building, you should obtain this tree: |
| |
| output/images/ |
| +-- rootfs.tar |
| +-- juno.dtb (if Juno r0 is used) |
| +-- juno-r1.dtb (if Juno r1 is used) |
| +-- juno-r2.dtb (if Juno r2 is used) |
| +-- Image |
| +-- bl1.bin |
| +-- bl2.bin |
| +-- bl2u.bin |
| +-- bl31.bin |
| +-- fip.bin |
| +-- scp-fw.bin |
| +-- u-boot.bin |
| |
| Preparing your rootfs |
| ====================== |
| |
| Format your pen drive as a ext3 filesystem by executing: |
| |
| $ mkfs.ext3 /dev/<your device> |
| |
| Preparing your rootfs |
| ====================== |
| |
| Format your pen drive as a ext3 filesystem by executing: |
| |
| $ mkfs.ext3 /dev/<your device> |
| |
| Installing your rootfs |
| ====================== |
| |
| After mounting the pen drive please execute the following: |
| |
| $ sudo tar -xvf output/images/rootfs.tar -C <pen drive mount path> |
| |
| When completed make sure to unmount the device: |
| |
| $ umount <pen drive mount path> |
| |
| Insert the pen drive in one of the ARM Juno' USB type A connectors. |
| |
| Configure *.dtb in the boot configuration for Juno r0 |

| |
| Installing kernel image and DTB |
| =============================== |
| |
| 1. Connect to the ARM Juno UART0 and execute USB_ON in the terminal |
| 2. Connect a USB cable between your PC and ARM Juno USB type B connector |
| A mass storage device should appear in your desktop. |
| 3. Open the software/ folder |
| 4. Copy the 'Image' file to software/ |
| 5. Copy the 'juno-r1.dtb' (r1), 'juno.dtb' (r0) or juno-r2.dtb (r2) file to software/ |
| 6. Copy the bootloader binaries (bl1.bin and fip.bin) to software/ |
| 7. Press the red button in the front pannel of ARM Juno |
| |
| At this time, the board will erase the Flash entry for each new item and |
| replace it with the lastest ones. |
