+# SDT BSP
+
+This section describes the SDT BSP settings which must be added to the generated
+machine configuration file, following [Build Instructions](README.md) step 4, in
+order to use the runqemu command.
+
+## SDT BSP settings
+
+The following board settings need to be added in sdt machine configuration file
+to define which QEMU device trees should be used.
+
+> **Variable usage examples:**
+>
+> QEMU Device tree deploy directory: `QEMU_HW_DTB_PATH = "${DEPLOY_DIR_IMAGE}/qemu-hw-devicetrees/multiarch"`
+> 
+> QEMU PMU Device tree: `QEMU_HW_DTB_PMU = "${QEMU_HW_DTB_PATH}/zynqmp-pmu.dtb"`
+> 
+> QEMU PMC Device tree: `QEMU_HW_DTB_PS = "${QEMU_HW_DTB_PATH}/board-versal-ps-vck190.dtb"`
+>
+> QEMU PS Board Device tree: `QEMU_HW_DTB_PMC = "${QEMU_HW_DTB_PATH}/board-versal-pmc-virt.dtb"`
