Dear @varada.k
Thank you for contacting the NVIDIA Developer Forum.

Hi vardhaman.k,
/dev/ttyAMA0
has been configured to 115200 as default in device tree for SBSA driver.
What’s your purpose to use this node?
You could try to modify current-speed
of serial@31d0000 in device tree (tegra234-soc-uart.dtsi)
Or you can try to just modify in kernel cmdline setting in p3701.conf.common
CMDLINE_ADD="... console=ttyAMA0, <baud rate> ..."
@KevinFFF any suggestion without rebuilding package, like application developer can change in target board. (one time reboot also accepted)
CMDLINE could also be found in /boot/extlinux/extlinux.conf.
Could you help to modify the baud rate of ttyAMA0
there?
