When we were trying download code to device through the Tag3, the UART_RX, UART_TX, and GND pins from Tag3 are connected to this external device. we experienced the code download fail because the device is not detected.  that means the RX, TX voltage are not correct.

Hello Ellen,

What are the Tx and Rx voltages that you see now on the external device?
