We have a custom carrier board working with the B01 Nano module. We are facing data packet loss issue on UART1_RXD pin 205.
Test Set up: Serial port 1 connected to serial port 2
Serial Console: Minicom
Ser 1 TX --> Ser 2 RX ==> Successful
Ser 2 TX --> Ser 1 RX ==> Fail
could you please try stopping and disabling the nvgetty service.
$ systemctl stop nvgetty $ systemctl disable nvgetty
My test set up is looping back from serial port 1 to serial port 2, ie ttyTHS1 connected to ttyTHS2. When I issue the above commands, I am unable to open both the serial ports at once on 2 different minicom terminals which I was able to prior to the issue of these commands.
could you please share more details of those two serial ports you’re used,
for example, which pin you’re used for serial-1, and serial-2.
once I pass these commands, I am unable to open the serial ports with Minicom simultaneously which I was able to prior to issuing these commands
Serial Port 1 --> UART0 from Nano --> Level Translator --> Multi protocol transceiver --> Connector
Serial Port 2 --> UART 1 from Nano --> Level Translator --> Multi protocol transceiver --> Connector
suggest you should narrow down the issue by excluding multi-protocol transceiver, thanks
