I have configured Axon V1.0 UART commincation to custom ipcb board. connection is pi pin no 8 as GND, 10 to IPCB TX, 12 to IPCB RX and aa to IPCB DIR. when i sending command for read voltage unable to get response from RX. Even after sending cmd onlt tx count increasing no change happening in rx count. i am using baud rate 115200 and ttyS1
I hope you are talking about UART Debug pins.
https://docs.vicharak.in/vicharak_sbcs/axon/axon-getting-started/#using-serial-console
For Debug UART Pins, baudrate is 1500000
Could you make video and send it over here!?
If you want to use GPIO pins as header than Kindly go through the documentation.
Kindly go through documentation again.
https://docs.vicharak.in/vicharak_sbcs/axon/peripherals/uart/
Could you confirm your overlays is turned it or not !?
cat /boot/extlinux/extlinux.conf and also make sure after enabling it, you have rebooted axon.
yes rebooted and extlinux.conf has ##/boot/extlinux/extlinux.conf

We have also tried with Axon To Axon communication using UART1 with 115200 baudrate.
Confirm wire health as well.
even for me when looping then working fine but i have connected with ipcb board, there i am getting issues. is there any way to find out whether communication is establishing or not
