Their solution only works straight from the .tcl command line.  My solution:

create a file named 'rp_post.tcl' and set it to run after bitstream generation via settings -> bitstream -> tcl.post

you could use the tcl command ''set_property STEPS.WRITE_BITSTREAM.TCL.POST ''??? (still figuring out syntax)

Got info from [[https://leiblog.wang/static/FPGA/books/Vivado%E4%BB%8E%E6%AD%A4%E5%BC%80%E5%A7%8B/Video_37_TCL_Vivado_One_World_3.pdf]]

File contents are:
<code>
set biffile [open "system_wrapper.bif" w+]
put $biffile "all:{ system_wrapper.bit }"
close $biffile
exec bootgen -image system_wrapper.bif -arch zynq -process_bitstream bin -o system_wrapper.bit.bin -w
</code>

This creates the ''system_wrapper.bif'' file and then does its magic to create a bootable bitstream

====  Other Info ====

To set up a file grab from another machine:

  - Grab https://gitforwindows.org/
  - Run it, use the command ''ssh-keygen'' to make a key pair
    - This is assuming we're calling it ''id_rsa''
  - copy the public key with something like ''ssh-copy-id -f -i id_rsa.pub root@red_pitaya_address''
  - log in via ''ssh -i id_rsa root@red_pitaya_address''
    - If the key isn't working, chmod 600 the ''.ssh'' directory and ''.ssh/authorized_keys'' file
