I set up the VM and downloaded dwm1001_on-board_package_v1p0.tar. I connected to the DWM1001 using minicom and did the si command:

I went through the process of updating the flash. In the dwm_simple directory I ran make recover (after installing openocd). I got the following:

Now the DWM1001 is unusable. It does not respond to minicom.
