Hi, I was wondering how can I configure, the UART four wire RTS as active high instead of active low. I include a screen capture of the current behavior as reference.
Also I tried using the supplied rubikpi_config tool and changing the DTS.
May I ask whether you are using the Linux version or another system image?
Would you share the patch you have modified?

Hi, sure.
We are currently syncing this issue internally.
We recommend using a Inverter Gate; alternatively, you can try to control the RTS signal manually via ioctl(TIOCM_RTS).
Thanks that worked for me
Good news. Thank you for your feedback.
