→Deploying the root file system onto the target
As <code>root</code>, copy the files from <code>/mnt/tmp/</code> to the desired partition into the microSD card.
After the copy operation is finished, unmount the microSD card and move it to the target.
To configure the SBCSPG to mount the root file system from this partition, several options are available. The following example shows how the U-Boot environment variables were set to retrieve the Linux kernel image and the device tree blob (DTB) via Ethernet, while the file system is mounted from the microSD card. In practice, an ad hoc variable—named <code>net_mmc</code> was —was added:
<pre class="board-terminal">
=> print net_mmc
