Hi @mahi ,
I am not sure why there is only one pin(only rx) in your UART.
Test with the following modification
&uart6 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_uart6>;
fsl,dte-mode;
status = "okay";
};
pinctrl_uart6: uart6grp {
fsl,pins = <
MX6UL_PAD_CSI_MCLK__UART6_DTE_RX 0x1b0b1
MX6UL_PAD_CSI_PIXCLK__UART6_DTE_TX 0x1b0b1
>;
};
Additionally, comment out SODIMM 75 and SODIMM 96 in pinctrl_gpio2: gpio2grp.
Compile the device tree and test.
