→Storing the images onto the raw partitions of the NAND memory
===Storing the images onto the raw partitions of the NAND memory===
Before storing the images onto into the NAND flash, the bitstrem bitstream must be converted. For more details, please refer to [[BELK-AN-008:_Programming_FPGA_Bitstream_with_U-Boot|this page]]:
<pre class="board-terminal">
$ python /devel/dave/bora-DBRx/fpga/fpga-bit-to-bin.py -f bitstream.bit bitstream.bin
</pre>
Once the U-Boot console is available, the binary files to be stored onto into the NAND flash can be downloaded via TFTP. The size of the partitions illustrated in the previous image determine the offsets to be used use with the <code>nand erase/write</code> commands. The following box shows the full procedure:.
The first file to be stored is <code>uImage</code>:
15280 bytes written: OK

===Setting up the U-Boot environment===
In order to boot the system as desired, the U-Boot environment must be configured properly. The most important variable is <code>nandboot2</code> that can be created as follows:
