6 These instructions apply to all models of the ARM Juno:
7 - Juno r0 (does not support PCIe)
8 - Juno r1 (supports PCIe)
9 - Juno r2 (Big Cluster with A72)
11 Buildroot will generate the kernel image, device tree blob, bootloader binaries
12 and a minimal root filesystem.
20 Configuring Buildroot is pretty simple, just execute:
22 $ make arm_juno_defconfig
24 Build the rootfs, kernel and DTB
25 --------------------------------
27 Note: you will need to have access to the network, since Buildroot will
28 download the packages' sources.
30 You may now build your rootfs with:
34 (This may take a while)
39 After building, you should obtain this tree:
43 +-- juno.dtb (if Juno r0 is used)
44 +-- juno-r1.dtb (if Juno r1 is used)
45 +-- juno-r2.dtb (if Juno r2 is used)
56 ======================
58 Format your pen drive as a ext3 filesystem by executing:
60 $ mkfs.ext3 /dev/<your device>
63 ======================
65 Format your pen drive as a ext3 filesystem by executing:
67 $ mkfs.ext3 /dev/<your device>
69 Installing your rootfs
70 ======================
72 After mounting the pen drive please execute the following:
74 $ sudo tar -xvf output/images/rootfs.tar -C <pen drive mount path>
76 When completed make sure to unmount the device:
78 $ umount <pen drive mount path>
80 Insert the pen drive in one of the ARM Juno' USB type A connectors.
82 Configure *.dtb in the boot configuration for Juno r0

121 Installing kernel image and DTB
122 ===============================
124 1. Connect to the ARM Juno UART0 and execute USB_ON in the terminal
125 2. Connect a USB cable between your PC and ARM Juno USB type B connector
126 A mass storage device should appear in your desktop.
127 3. Open the software/ folder
128 4. Copy the 'Image' file to software/
129 5. Copy the 'juno-r1.dtb' (r1), 'juno.dtb' (r0) or juno-r2.dtb (r2) file to software/
130 6. Copy the bootloader binaries (bl1.bin and fip.bin) to software/
131 7. Press the red button in the front pannel of ARM Juno
133 At this time, the board will erase the Flash entry for each new item and
134 replace it with the lastest ones.
