This page is a collection of notes on the Red Pitaya platform

The chip used is a xc7z010clg400-1

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: 

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

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:

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