Running UARTE0 at 115200

Hi,

 Whenever I try to run the NUS example at 115200 baudrate there is an error. Either it triggers an assert or I receive corrupted data.

What should be the ideal baud rate? Is there any specific reason for this error?

Chipset : 52832

nRF Connect SDK V2.0.2

Here is my proj.conf

CONFIG_UART_ASYNC_API=y
CONFIG_NRFX_UARTE0=y
CONFIG_SERIAL=y

and app overlay

arduino_serial: &uart0 {
    status = "okay";
    compatible = "nordic,nrf-uarte";
    current-speed = <115200>;
    pinctrl-0 = <&uart0_default>;
    pinctrl-1 = <&uart0_sleep>;
    pinctrl-names = "default", "sleep";
};
Please note this works fine at low baud rates.

Thanks in advance.
