Part Number: AM5706
Dear Team,
I am using AM5706 in my project and using UART3 and UART9 for serial communication. So made 2 Boards and I am facing the following issues. The UARTs are converted to RS422 to connect to the PC.
- Board 1
- UART9 is working fine
- UART3 Transmit is working, same signal is probed and observed as expected
- UART3 Recieve is not working. The UART is probed after the RS422 conversion (near processor) the signal is as expected.
- Board 2
- UART9 is working fine
- UART3 Transmit is happening, but the serial terminal we are observing gabage characters.
- UART3 Recieve is not working. The UART is probed after the RS422 conversion (near processor) the signal is as expected.
- In UART3 only TX and RX signal are used
Schematic design of UART is attached for reference
Please help me solve this issue
