I'm unable to make UART serial communication with FX3. I tried UartLpRegMode example. When I single stepped through my code with a J-link segger debugger, I realized that rxTxByte is always zero and apiRetStatus is 69. I'm not getting anything on the serial terminal when I set to the baud rate I configured in the program. Tried putting some CyU3PDebugPrint statements, but nothing is getting printed. Even, after configuring the UART. Tried shorting TXD and RXD pins to see any loopback, but no improvements. Even manual values are not getting printed. I'm not sure, whether I'm running properly and testing. Any suggestions would be greatly helpful. Thanks for helping !

Hi,
How are you sending the bytes to FX3's rx? Make sure the device that send the bytes configured to the same baud rate?
Also, DebugPrints will not work in this code, as UART is used for serial communication here.
