I am using several CY8CKIT-059 's in my project. On one (my Master) I use the UART on the KitProg end. On the other 8 (Slaves), I do not need the UART. I removed the KitProg from the target boards and installed 5 pin m/f headers so I can program them. That works. But I cannot use the UART. Should I be able to use it if I reconnect the KitProg with the 5 pins inthe header?
On the slaves I had used the UART for debugging but I do not need it. When I removed the KitProg, I found they would not operate correctly until I removed references to the UART from my code. Is that normal?
I noticed that when I snapped the KitProg from the board, there appeared to several PCB traces in addition to the obvious 5 pins. I cannot find an accurate schematic of the boards. Are ther more than the five connections between the target an dprogrammer?

Please note that Kitprog acts as a USB-UART bridge to the target device as shown below:
So, on the slaves if you snap off the Kitprog and want UART for debugging purposes, then follow these steps:
#1: You can program the target using the 5 pin M/F headers
#2: You must unpopulate R22, R23 to isolate UART_TX and UART_RX lines of the Kitprog from the target
#3: Connect the FTDI (USB to Serial converter) on these pins to observe the serial output
Using the Kitprog on the slaves for UART seems like a better option. So, you could consider connecting it back.
The signals coming in to the target from the Kitprog are shown below:
