We regret to say that presently it is not possible to use Cypress programmers like Miniprog 3/Miniprog 4/Kitprog with IAR Embedded workbench. You need to use either J-Link/ I-Jet to program the devices through IAR.
Cypress is actively working to add support for PSoC 4 in Modus Toolbox though PDL in the near future. Then you can use cypress programmers to program your applications over Windows, Linux and Mac.
I got it.
I will try using Jlink.
