The microSD card provided with BELK/BXELK is partitioned as shown in the following image:
It is worth remembering that the microSD card is [[System boot and recovery via microSD card (BELK/BXELK)|bootable]] and U-Boot environment is retrieved from (and stored to with <code>saveenv</code>) into the FAT partition as <code>bora.env</code>

=== Updating git repositories ===
In BELK/BXELK, the following source trees are clones of the correspondent '''DAVE Embedded Systems''' git repositories:

<section begin=Synchronizingthegitrepositories/>
=== Synchronizing the repositories ===
When the account is enabled, you can synchronize a source tree entering the repository directory and launching the <code>git fetch</code> command. Please note that <code>git fetch</code> doesn't merge the commits on the current branch. To do that, you should run the <code>git merge</code> command or replace the ''fetch-merge'' process with a single <code>git pull</code> command. Please note that the recommended method is the ''fetch-merge'' process. For further information on Git, please refer to [http://git-scm.com/documentation Git Documentation].
