Generate .dcf file

$ dlet -f <input .hwh file>
$ mkdir arch/<platform name>
$ mv <generated file> arch/<platform name>/<platform name>.dcf

• For example:

$ dlet -f ultra96v2.hwh
$ mkdir arch/ultra96v2
$ mv dpu-03-26-2020-13-30.dcf arch/ultra96v2/ultra96v2.dcf

Edit arch/arch.json

• Add path the .dcf file path (relative to the model directory of your choice) to "dcf" section of arch/arch.json

• For example, arch/arch.json will look like:

{
    "target"   : "dpuv2",
    "dcf"      : "../arch/ultra96v2/ultra96v2.dcf",
    "cpu_arch" : "arm64"
}

• Copy edited arch.json into arch/<platform name>

$ mv arch/arch.json arch/<platform name>
