Separate board MK20 and MKL02

[rabbit20]

Hi all,
I new in teensy. Now I would like to know I can run MK20 after i program with separate MKL02 board. I finish my project with teensy3.2 but I want to make my board without MKL02. Let me know about that.

Sure, you can do that. There are multiple posts on this forum about this.
But why do you want to do that?
if you build a board without the bootloader chip, then you need other means to program the MK20. That is fine, but such a board is not a teensy, and you do not need a teensy to develop SW, do it directly on your new board, with SWD or JTAG programming.
The teensy is all about the idea that the bootloader is in a separate chip, removing the worries about bootloader SW
