+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)
|
|
|
+
|
|
|
+Buildroot will generate the kernel image, device tree blob 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)
|
|
|
+ +-- Image
|
|
|
+
|
|
|
+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) or the 'juno.dtb' (r0) file to software/
|
|
|
+6. 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.
