The Make Target for programming CYBT-343026-01 module should be-
<name of app with path>-CYBT_343026_EVAL download UART=COM36
where COM36 is HCI UART.
For ex. demo.hello_sensor-CYBT_343026_EVAL download UART=COM36
You can use following methods to program the module:

Thank you for your response. I switched the Make Target name as you advised, and was able to use the CyBluetool to send the reset command to the chip (as recommended at the bottom of your second link), and that appeared to do the trick. From there I was able to re-program the device without having to physically pull any pins to reset the device.
