Hi:

     I use the Code Example "USBBulkLoopAuto",and use the CyU3PDebugPrint  api to add some debug message,

eventhough   i have change the CY_U3P_IO_MATRIX_LPP_UART_ONLY to CY_U3P_IO_MATRIX_LPP_DEFAULT for CX3

but i also can't get the message output from the CX3 uart.

    can you help me,thank you very much!

Hi,

>>>Are you using CX3 RDK or custom hardware? Please attach the schematic of the board.

>>>Where is the UART line of CX3 connected to? Is it to another UART-USB chip/cable?

>>>Can you please probe the UART TX signal and check if there signal is toggling as expected? Please add the screenshot here.
