===== Building a custom U-Boot =====

Requirements:
  * gmake
  * gsed

First build the xdev target:

<code>
$ cd freebsd
$ make xdev XDEV=arm XDEV_ARCH=arm
</code>

Then build U-Boot:

<code>
$ git clone https://github.com/rpaulo/uboot-ccwmx53-digi.git
$ cd uboot-ccwmx53-digi
$ gmake ccwmx51js_config
$ gmake CROSS_COMPILE=armv6-freebsd-
</code>

===== Replacing the U-Boot in flash =====

  * Setup DHCP and a TFTP server serving %%%%''%%u-boot-ccwmx53js.bin%%''%%%%.
  * Type %%%%''%%update uboot%%''%%%%
  * Answer the questions and U-Boot will update itself

If you end up installing a broken U-Boot, you can still boot off SD card. See the next section.

===== U-Boot from SD card =====

To boot U-Boot from the SD card slot, change S8 (near Camera 1) to this configuration:

| BOOT | down, up |
| CONF | up, up |

You need to ''%%dd%%'' ''%%u-boot-ccwmx53js.bin%%'' to the first sectors of the SD card to be able to boot.

===== U-Boot setup for network booting (ubldr) =====

<code>
setenv loadbootsc 0
setenv bootcmd 'dhcp; go 0x70800054'
saveenv
reset
</code>

===== U-Boot setup for network booting (kernel booting) =====

<code>
setenv loadbootsc 0
setenv bootcmd 'dhcp; tftpboot 0x70800000 kernel.ccwmx53; go 0x70800100'
saveenv
reset
</code>
