Hi,
1. I want use UART1 for RS232 communication. for RTS and CTS lines i want use UART4_Tx and UART_Rx. Is that the right way to do ? How to change the device tree for this configuration.
2. And also anyone help me to write a device tree changes procedure to connect I2C expander to I2C3 bus.
3. How to write a device tree for registering the pins for GPIO.
Thanks in Advance,
Srinu Inaganti
Hi Srinu
from Reference Manual UART1 RTS and CTS are available on UART3, not UART4
both UART3,4 are used on board:
for device tree customization one can look at

This board was produced by boundary devices and issue may be posted on its
forum: https://boundarydevices.com/wiki/nitrogen8m-som/
Best regards
igor
