Building

--------

Return to the top directory <buildrootdir> and execute the following commands.

  make arcturus_ucls1012a_defconfig

  make

Result of the build

-------------------

After building, you should obtain this tree:

    output/images/

    +-- arc-ucls1012a.dtb

    +-- Image

    +-- part0-000000.itb

    +-- rootfs.cpio

    +-- rootfs.cpio.gz

    +-- rootfs.tar

    +-- u-boot.bin

    +-- ucls1012a.its

Flashing

--------

You'll need to program the image created by buildroot into the SPI NOR flash.

1. Reboot your module and via the serial console press <escape> to enter the B$

u-boot shell.

   From the shell you will need to update four environment variables replacing the

   IPv4 IP Address with ones that will work with your network and tftp server.

   B$ setenv ipaddr 192.168.1.81

   B$ setenv serverip 192.168.1.80

   B$ setenv gatewayip 192.168.1.1

   B$ setenv netmask 255.255.255.0

   B$ saveenv

2. Enable tftp server to serve the <buildrootdir>/output/images/ folder.

3. 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$ run program_uboot

4. Program the ITB image (includes Kernel, DTB and Ramdisk)

    B$ tftp part0-000000.itb

    B$ run iprogram
