TMDXIDK5718: To disable UART3 as a console and using for my application

Part Number: TMDXIDK5718
Other Parts Discussed in Thread: AM5718, DRA722, PMP

Hi TI Team,

I am using TMDXIDK5718, REV 1.3B and ti-processor-sdk-linux-rt-am57xx-evm-06.02.00.81-Linux-x86-Install.

This is working fine and i can see complete log on tera term.

My Question: I am trying to disable UART3(ttyS2) as console and want to use this for my different serial application.

(1) I have made following changes in /board-support/u-boot-2019.01+gitAUTOINC+a141f7abfd-ga141f7abfd/arch/arm/dts/am57xx-idk-common.dtsi.Compiled u-Boot, Copied new MLO and u-boot.img in SD card.

chosen {
stdout-path = &uart1;
};

&uart1 {
status = "okay";
interrupts-extended = <&crossbar_mpu GIC_SPI 67 IRQ_TYPE_LEVEL_HIGH
&dra7_pmx_core 0x3E0>;
};

(2) I have made following changes in /board-support/linux-rt-4.19.79+gitAUTOINC+5baf382c8f-g5baf382c8f/arch/arm/boot/dts/am57xx-idk-common.dtsi. I Compiled am571x-idk.dts to am571x-idk.dtb file and copied in /rootfs/boot of the SD card.

chosen {
stdout-path = &uart1;
};


&uart1 {
status = "okay";
interrupts-extended = <&crossbar_mpu GIC_SPI 67 IRQ_TYPE_LEVEL_HIGH
&dra7_pmx_core 0x3E0>;
};
&uart3 {
status = "okay";
};

After inserting SD card in Board, following messages appear on tera term. Please help me for what i am missing to disable UART3 as a console.

  • Hi Mahesh,

    So u-boot prints are no longer coming on UART3 after yor changes.

    console=ttyS2 so you need to remove that from your bootargs in uboot. It is telling the kernel that
    UART3 should be used for console.

    Also the filesystem will be using the UART3 for console:

    search for ttyS2 name under /etc/systemd.
    Remove the entried you find or just rename it.

    UART3 should be free for your use.

    Ex: mv /etc/systemd/system/getty.target.wants/serial-getty@ttyS2.service /etc/systemd/system/getty.target.wants/serial-getty@ttyS2.service_bk

    Regards,
    Keerthy
