I have kc705 board and vivado 2019.1.1 any basic tutorials or codes are there to test the board or practice? please give some simple exercise along with constraints file and dont refer some ugXXX pdf file.
I know you don't want PDFs, but UG882 is the user guide for the KC705 Targeted Reference Design - a project specifically built to test (and demonstrate the features of) the KC705. There's also XTP195, which is for the KC705 Built In Self Test (may not still be built-in if you've put something else in the flash).
I'd start with the BIST, then pull that apart and insert your own code to (for example) read from buttons and drive the LEDs.
