= Barebox =

Barebox uses the same build (Kbuild) and configuration (Kconfig) tools as the Linux kernel.

1) First you need to clone the tree

git clone git://git.pengutronix.de/git/barebox.git

Most probably you want to use a released Barebox version, by running 'git checkout <version>'. Check which versions are available with 'git tag -l' and use the latest one.

2) Then you need to configure it:

make mini2440_defconfig

3) Compile it

make

4) Now you need to flash the nand for this you can use OpenOCD

= OpenOCD =

now you need so start OpenOCD. For this you need to specify the interface (First) and then the board

for this I just a Jlink

openocd -f interface/jlink.cfg -f target/samsung_s3c2440.cfg -c "adapter_khz 12000"

Flashing barebox
And then the following steps:
*connect a terminal application to the mini2440's serial connector
*connect the mini2440 to a working network
*switch S2 to boot from NOR to boot into 'supervivi'
*switch on your mini2440
*run the OpenOCD daemon configured with the file shown above
*connect to the OpenOCD daemon via 'telnet'.
*run the following commands to download @a barebox into your target

> halt
> load_image \<path to the 'barebox.bin'\> 0x31000000 bin
> resume 0x31000000

Now a barebox is starting from an already initialized CPU and SDRAM (done by
'supervivi').

Change to your terminal console and configure the network first. Adapt the
following settings to your network:

eth0.ipaddr=192.168.1.240
eth0.netmask=255.255.255.0
eth0.gateway=192.168.23.2
eth0.serverip=192.168.1.7

A 'ping' to your TFTP server should bring a "...is alive" message now.

We are ready now to program @a barebox into the NAND flash:

erase /dev/nand0.barebox.bb
tftp barebox.bin /dev/nand0.barebox.bb
