Can I use UART_2_RTS and UART_2_CTS pins for the communication between Jetson Nano and Pixhawk 4 (TELEM2 port)?

hello furkan.nargul,

J44 is a serial port header, the default baudrate is 115200/8n1,
please also refer to device tree, there’re definition for the uart ports.
for example,
$L4T_Sources/r32.6.1/T186/Linux_for_Tegra/source/public/hardware/nvidia/platform/t210/porg/kernel-dts/tegra210-porg-p3448-common.dtsi

        serial@70006000 { /* UART-A : UART1: Debug */
                compatible = "nvidia,tegra210-uart", "nvidia,tegra114-hsuart", "nvidia,tegra20-uart";
                console-port;
                sqa-automation-port;
                /delete-property/ resets;
                /delete-property/ reset-names;
                status = "okay";
        };

        serial@70006040 { /* UART-B : UART2 40 pin header */
                compatible = "nvidia,tegra114-hsuart";
                status = "okay";
        };

        serial@70006200 { /* UART-C : UART3 : M.2 Key E */
                compatible = "nvidia,tegra114-hsuart";
                dma-names = "tx";
                nvidia,adjust-baud-rates = <921600 921600 100>;
                status = "okay";
        };
