==microSD card==
microSD card on connector <code>J21</code>, if present, will be associated by the Linux kernel to the <code>mmcblk0</code> device:
<pre class="workstation-terminal">
[ 0.740571] mmc0: SDHCI controller on e0100000.mmc [e0100000.mmc] using ADMA
...
[ 0.824174] mmc0: new high speed SDHC card at address aaaa
[ 0.830415] mmcblk0: mmc0:aaaa SA16G 14.8 GiB
[ 0.837970] mmcblk0: p1 p2
</pre>
Once detected, it can be mounted and accessed via usual Linux commands:
<pre class="workstation-terminal">
