+\section{Creating the SDcard}
+
+Because Android has permissions issues when using an NFS volume as
+\code{/data}, we have to use an Android SDcard that we'll let in the
+slot. Android will mount it and use it for \code{/data}.

+sudo ./external/ti_android_utilities/am335x/mk-mmc/mkmmc-android.sh \
+  /dev/sdX u-boot/MLO u-boot/u-boot.img kernel/arch/arm/boot/uImage \
+  ./external/ti_android_utilities/am335x/u-boot-env/uEnv_beagleboneblack.txt \
