    lab-data: bbb-recovery: Roll back to v2021.01 which is more stable
    
    The following thread summarizes the problem. Somewhere when there is a
    network related command which is handled over USB (ethernet gadget),
    there is an environment variable that gets set and a malloc that is
    being done which (sometimes) leads to a data abort.
    
    Running "fastboot usb 0; Ctrl-C" makes it magically work.
    
    Let's switch back to a more stable U-Boot version while the
    investigations are ongoing.
