The short answer is no, because of inherent differences in the two MiniProg vs. KitProg. As shown in the schematics for the CY8CKIT-042-BLE main board, the KitProg interface is actually a PSoC 5LP which connects to the target's debug interface as well as one UART pin set (P1.4/P1.5) and one I2C pin set (P3.4/P3.5 if memory serves). This allows the single 5LP-based KitProg programmer to provide a USB-to-UART bridge in addition to the debugging capabilities.
On the other hand, the MiniProg 5-pin header connects to the debug interface alone (GND, VDDIO, XRES, SWCLK, SWDIO), but no other pins. (The 10-pin header adds some JTAG pins, but not UART.)
However, with this in mind, you can replicate the KitProg's virtual serial interface on your second device by connecting a USB-to-UART adapter (e.g. CYUSBS232, FTDI adapter, etc.) to the P1.4 and P1.5 pins on the module--or, if you only need output, all you need is the P1.5 pin.
Ok. I see what you mean. Thank you for the help. I can spare the extra pin(s) and have an FTDI, so I'll give that a try.
