You can program the device using Kitprog and external power supply. For that you have to use RESET programming mode. Connect GND, XRES, SWD_IO and SWD_CLK of the Kitprog to your board (do not connect power supply), power the board using external power supply and program the device.
Please update if you have any queries.
Thanks and regards
thanks for your answer. I didn't try this method yet, but I solved my problem with Cypress MiniProg3. This device doesn't power the entire cypress board, only KitProg section. And it can be flashed if I use external power supply for the target board. That's exactly what I need.
