TDA4VM: Change the UART Debug Console

I have made changes in both U-boot device tree as well as the kernel device tree

&main_pmx0 {
	main_uart0_pins_default: main-uart0-default-pins {
		pinctrl-single,pins = <
			J721E_IOPAD(0x1d4, PIN_INPUT, 1) /* (Y3) SPI1_CS0.UART0_CTSn */
			J721E_IOPAD(0x1c0, PIN_OUTPUT, 1) /* (AA2) SPI0_CS0.UART0_RTSn */
			J721E_IOPAD(0x1e8, PIN_INPUT, 0) /* (AB2) UART0_RXD */
			J721E_IOPAD(0x1ec, PIN_OUTPUT, 0) /* (AB3) UART0_TXD */
		>;
		/*bootph-all;*/
	};

	main_uart1_pins_default: main-uart1-default-pins {
		pinctrl-single,pins = <
			J721E_IOPAD(0x1f8, PIN_INPUT, 0) /* (AA4) UART1_RXD */
			J721E_IOPAD(0x1fc, PIN_OUTPUT, 0) /* (AB4) UART1_TXD */
		>;
		bootph-all;
	};
	}
	
	&main_uart0 {
	status = "okay";
	pinctrl-names = "default";
	pinctrl-0 = <&main_uart0_pins_default>;
	/* Shared with ATF on this platform */
	power-domains = <&k3_pds 146 TI_SCI_PD_SHARED>;
	/*bootph-all;*/
};

&main_uart1 {
	status = "okay";
	pinctrl-names = "default";
	pinctrl-0 = <&main_uart1_pins_default>;
	power-domains = <&k3_pds 278 TI_SCI_PD_SHARED>;
	bootph-all;
};

these are the changes i have made and my board is not getting booted

Thanks

Hi

this you have sent for normal UART communication, but i want to switch my boot log terminal from main UART0 to Main UART1.

Thanks

Hi,

1.I have made some changes in

	aliases {
		serial0 = &wkup_uart0;
		serial1 = &mcu_uart0;
		serial2 = &main_uart0;
		serial3 = &main_uart1;
		serial4 = &main_uart2;
		serial6 = &main_uart4;
		ethernet0 = &cpsw_port1;
		mmc0 = &main_sdhci0;
		mmc1 = &main_sdhci1;
	};

	chosen {
	-	stdout-path = "serial2:115200n8";
	+   stdout-path = "serial3:115200n8";
	};
	
	&main_pmx0 {	
	main_uart0_pins_default: main-uart0-default-pins {
		pinctrl-single,pins = <
			J721E_IOPAD(0x1d4, PIN_INPUT, 1) /* (Y3) SPI1_CS0.UART0_CTSn */
			J721E_IOPAD(0x1c0, PIN_OUTPUT, 1) /* (AA2) SPI0_CS0.UART0_RTSn */
			J721E_IOPAD(0x1e8, PIN_INPUT, 0) /* (AB2) UART0_RXD */
			J721E_IOPAD(0x1ec, PIN_OUTPUT, 0) /* (AB3) UART0_TXD */
		>;
		bootph-all;
	};

	main_uart1_pins_default: main-uart1-default-pins {
		pinctrl-single,pins = <
			J721E_IOPAD(0x1f8, PIN_INPUT, 0) /* (AA4) UART1_RXD */
			J721E_IOPAD(0x1fc, PIN_OUTPUT, 0) /* (AB4) UART1_TXD */
		>;
		bootph-all;
	};
};

&main_uart0 {
	status = "okay";
	pinctrl-names = "default";
	pinctrl-0 = <&main_uart0_pins_default>;
	/* Shared with ATF on this platform */
	power-domains = <&k3_pds 146 TI_SCI_PD_SHARED>;
	bootph-all;
};

&main_uart1 {
	status = "okay";
	pinctrl-names = "default";
	pinctrl-0 = <&main_uart1_pins_default>;
	power-domains = <&k3_pds 278 TI_SCI_PD_SHARED>;
	bootph-all;
};

then i built my u boot and kernel and i turned ON my board the board was not booted

Thanks

Hi,

By using this command(setenv console ttyS3,115200n8) in the uboot environment the uart console is change.

But it always starts the kernel Log in the UART1, i need uboot log also to be printed in main UART1.

Thanks
