I did have one set up but it broke. I got a second one and made a
start, but didn't finish it. Edison has a somewhat painful

FWIW here is my tboot flash script for Edison:

    def flash_edison(self, repo):
        vid = 0x8086
        pid = 0xe005
        expect = "%04x:%04x" % (vid, pid)
        self.wait_for_dfu(expect)
        u_boot = os.path.join(repo._local_str(), "u-boot-edison.img")
        bindir = self.usbboot_xfstk_dir
        self.host.exec0(
            "xfstk-dldr-solo", "--gpflags", "0x80000007",
            "--osimage", u_boot,
            "--fwdnx", os.path.join(bindir, "edison_dnx_fwr.bin"),
            "--fwimage", os.path.join(bindir, "edison_ifwi-dbg-00.bin"),
            "--osdnx", os.path.join(bindir, "edison_dnx_osr.bin"))
