Hello Andrew,
You don't need an OpenSDA on your custom board. Will you want to debug the program in your custom board or just download the image? If you want to do both things, then you can use an external debugger, you just need to have either an SWD or JTAG interface in your custom board.
If you don't care about the debug part, then you need neither the OpenSDA nor an external debugger, you can download your application using the NXP-MCUBootUtility. This tool supports UART as well as USB to communicate with the RT, are you interested only in the UART interface? If you want to test the UART in the RT1020-EVK, the first thing is to consider is that you can only use the pins specified in Table 8-1 of the RM.
As you can see in the schematic of the board, these two pins are accessible through the Arduino Interface in the J17.
You will need a USB to serial converter so you can try the NXP-MCUBootUtility with the UART.
Have a great day,
Victor
