Changing drive strength of Debug UART

Hi Team
We want to increase the drive strength of Debug Uart .Basically we are directly connected Uart pins to Uart to TTL converter at 1.8 V . Hence level shifter is not available at our board ,As soon as we connect UART to TTL convert our Uart signal get distorted.

How we can increase the drive strength of these signals so that we can able to get debug log during booting .

hello abhishek.singh,

may I know what’s your use-case?
please also share what’s the pin connection you’re used for debug uart;
since NX and Nano were sharing the same base board, you may also refer to https://www.jetsonhacks.com/2019/04/19/jetson-nano-serial-console/ for setup serial ports.

BTW,
drive strength is configured in device tree, please also refer to Topic 73904 to configure the drive strength.
thanks
