+Arcturus uCP1020 SoM
+====================
+
+This tutorial describes how to use the predefined Buildroot
+configuration for the Arcturus uCP1020 SoM platform.
+
+Additional information about this module can be found at
+<www.arcturusnetworks.com/products/ucp1020>
+
+Building
+--------
+
+  make arcturus_ucp1020_defconfig
+  make
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+    output/images/
+    +-- rootfs.jffs2
+    +-- rootfs.tar
+    +-- u-boot.bin
+    +-- ucp1020.dtb
+    +-- uImage
+
+Flashing
+--------
+
+You'll need to program the files created by buildroot into the NOR flash.
+
+1. Program the new U-Boot binary (optional)
+    If you don't feel confident upgrading your bootloader then don't do it,
+    it's unnecessary most of the time.
+
+    B$ tftp u-boot.bin
+    B$ protect off 0xeff80000 +$filesize
+    B$ erase 0xeff80000 +$filesize
+    B$ cp.b $loadaddr 0xeff80000 $filesize
+    B$ protect on 0xeff80000 +$filesize
+
+2. Program the kernel
+
+    B$ tftp uImage
+    B$ erase 0xec140000 +$filesize
+    B$ cp.b $loadaddr 0xec140000 $filesize
+
+3. Program the DTB
+
+    B$ tftp ucp1020.dtb
+    B$ erase 0xec100000 +$filesize
+    B$ cp.b $loadaddr 0xec100000 $filesize
+
+4. Program the jffs2 root filesystem
+
+    B$ tftp rootfs.jffs2
+    B$ erase 0xec800000 0xee8fffff
+    B$ cp.b $loadaddr 0xec800000 $filesize
+
+5. Booting your new system
+
+    B$ setenv norboot 'setenv bootargs root=/dev/mtdblock1 rootfstype=jffs2 console=$consoledev,$baudrate;bootm 0xec140000 - 0xec100000'
+
+    If you want to set this boot option as default:
+
+    B$ setenv bootcmd 'run norboot'
+    B$ saveenv
+
+    ...or for a single boot:
+
+    B$ run norboot
+
+Good Luck !
