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!
>>>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.
