Hi，TI
Our products contain two channels of RS-485 interfaces. In the test, the baud rate of 115200 was used to send data between two channels of RS-485. The test results showed that one of the channels failed to receive RS-485. After that, the serial port debugging tool was used on the problem board to conduct the transceiver test at baud rate of 115200. When the result was partial, the single character could be sent, but the sending failure or garbled character would appear in the long string.

Actual send information:
Figure 3. Long string to receive
Attached is the schematic diagram, please help to confirm whether abnormal RS485 is caused by design reasons
