Hello,
I am currently working on the CY8CKIT-059 to interface with an external PSoC 4 MCU (CY8C4014SXI-421; 16-pin SOIC). But since the external PSoC 4 doesn't have an external reset pin (XRES) like other PSoC 4 packages but only has an internal Reset Pin on port P1_6, whereas the SWD interface from the Kit Prog board of the CY8CKIT-059 has a reset, I thought of checking whether using the SWDIO, SWDCLK and GND pins to interface the external PSoC 4 from Kit Prog can provide a complete interface to program the device. I am also using an external power supply to the PSoC 4 as it uses a 3.3 V and is not using the VTARG (5 V) pin on the Kit Prog board.
Please kindly advise me regarding this concern.
Thanks & Regards,

See the following for info to use Kitprog to program any PSoC without external reset pin.
Solution: Use Kitprog to Program PSoC 4000 without XRES pin
It also mentions programming at 3.3V and the simple mod to Kitprog to make it compatible at this voltage.

Hello !
Thank you very much for guiding me to the right source. From reading the post I could see that I would have to include extra logic aprt from using CY8CKIT-059 to program the chips as the WLCSP package doesn't have XRES pin to establish an SWD interface between the KitProg and the PSoC 4 device. But since I have to preprogram more than 50 PSoC 4 16 - pin WLCSP chips (CY8C4014FNI-421AT) before soldering it onto the target PCB, and also, i am not going to include the SWD option on the target prototype board, I looked up for additional resources online to see whether there is a header for the Ball Grid Array, that I can use to preprogram using the Kit Prog and then permanently solder it on to the target PCB. I also learnt from the support community that Cypress doesn't preprogram chips upon request from a customer.
It will be great if you will be able to advise me on possible options to preprogram a WLCSP PSoC 4 device (CY8C4014FNI-421AT) before soldering it onto a target device.
Wish you have a great day!
Thanks and Regards,

Cypress has a list of companies who sell programmers for their devices. Maybe one of them offers a pre-program service.

Good luck with your product.
