# 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 PS Device tree: `QEMU_HW_DTB_PS = "${QEMU_HW_DTB_PATH}/board-versal-ps-vck190.dtb"`
>
> QEMU PMC Board Device tree: `QEMU_HW_DTB_PMC = "${QEMU_HW_DTB_PATH}/board-versal-pmc-virt.dtb"`
>
> QEMU Memory: Some boards for example VEK280 and VH158 memory configurations are
> different, Hence we need to adjust the same in QB_MEM to match board dtsi files.
> Below are some examples.
> * ZynqMP `QB_MEM = "-m 4096"`
> * Versal VEK280 `QB_MEM = "-m 12G"`
