Boot into login console on LCD

Other Parts Discussed in Thread: TPS65910, DA8XX

Hi...

I have an AM335X Starter Kit, on which I am running Linux built from the SDK to an SD Card.

By default, when Linux boots, I can see the boot log through serial terminal (over USB) with minicom from another Linux. And it starts matrix-gui on the LCD, which can be interacted through touchscreen. I have disabled matrix-gui service from /etc/rc5.d, and after booting, the LCD displays an empty screen now, which I can dump garbage to with 'cat /dev/urandom > /dev/fb0'

Instead of the serial terminal over minicom, I would like to see the Linux boot messages on the LCD on a console, and I would like Linux to boot into a root shell on the LCD, to which I can connect mouse and keyboard and run shell commands on. Very much like normal Linux desktops, that have multiple virtual terminals that can be switched with Ctrl+Alt+Fn and logged in to.

Can someone give some tips, or point me to some documentation/thread that achieves this through follow-through instructions? Kernel menuconfig? /etc/inittab? bootargs? ...?

Thanks in advance...

  • Hi,

    Can you please change the "console=/dev/ttyS0" bootargs variable to "/dev/fb0"

    And enable the below configurations in linux menuconfig

    CONFIG_FRAMEBUFFER_CONSOLE

    CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY

    Ex:

    setenv bootargs mem=32M console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootfstype=ext3 rw rootwait ip=10.100.1.90

    TO

    setenv bootargs mem=32M console=/dev/fb0,115200n8 root=/dev/mmcblk0p2 rootfstype=ext3 rw rootwait ip=10.100.1.90

  • Hi. Thanks for the reply. I did try, but still somethings seem amiss.

    > grep CONFIG_FRAMEBUFFER_CONSOLE .config

    CONFIG_FRAMEBUFFER_CONSOLE=y
    CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y
    # CONFIG_FRAMEBUFFER_CONSOLE_ROTATION is not set

    > uEnv.txt on first partition of the SD card:

    bootargs=console=/dev/fb0,115200n8 root=/dev/mmcblk0p2 mem=128M rootwait
    bootcmd=mmc rescan; fatload mmc 0 0x82000000 uImage; bootm 0x82000000
    uenvcmd=boot

    With these settings, I see u-boot messages on minicom until "Uncompressing Linux... done, booting the kernel."

    Then no messages appear neither on minicom, nor on board LCD. The penguin image stays on LCD until boot is complete. And then on minicom, I get the login prompt, while LCD is blank.

    Do I need to set up /etc/inittab, too? Maybe, update the following line?

    1:2345:respawn:/sbin/getty 38400 tty1

  • Hi,

    Do I need to set up /etc/inittab, too? Maybe, update the following line?

    1:2345:respawn:/sbin/getty 38400 tty1

    It is not required because "inittab" is called once you get mounted using your fs, but you need to redirect all the logs including kernle logs know!

    Try "console=/dev/ttySA0" in bootargs.

  • I have tried with a bunch of options in uEnv.txt

    tty, tty0, tty1, tty2, ttyO0, ttyO1, ttyO2, fb0, /dev/fb0


    Some affect the behavior of the kernel boot messages, so, I am guessing the uEnv.txt (under first partition - mmcblk0p1) is working fine. But maybe some other thing is affecting the result. In the kernel .config file, there is also a CONFIG_CMDLINE, does it affect anything? *_FROM_BOOTLOADER sounds like it is picking the CMDLINE from bootloader rather than the hardcoded value.

    CONFIG_CMDLINE="root=/dev/mmcblk0p2 rootwait console=ttyO0,115200"
    CONFIG_CMDLINE_FROM_BOOTLOADER=y

    Do you know what the list of commands to run would be, if I switch to U-boot prompt and boot from there with commands?

  • Hi,

    Please check your "kernel command line" variable after linux boots-up to check whether the bootargs taking from u-boot env or default which is give through kernel menuconfig option.

    > uEnv.txt on first partition of the SD card:

    Please confirm that u-boot args has taken from "uEnv.txt" or some where else by modifying the u-boot args.

  • still didn't manage to get boot messages on LCD.

    - kernel config has CONFIG_FRAMEBUFFER_CONSOLE and CONFIG_FRAMEBUFFER_DETECT_PRIMARY

    - tried uEnv.txt with different console arguments

        - tty, tty0, tty1, tty2, ttyO0, ttyO1, ttyO2, ttySA0, fb, fb0, vcs, vcs1, vcsa, vcsa1

        - same devices with /dev prepended to the names

        - the kernel log shows the updated console message, such as "Jun 26 00:11:59 am335x-evm user.notice kernel: [    0.000000] Kernel command line: console=ttySA0,115200n8 root=/dev/mmcblk0p2 mem=128M rootwait"

        - only for ttyO0, the serial terminal displays the boot messages. for all the others, kernel booting messages are not visible.


    When kernel boot starts, the LCD shows the penguin, but no more messages. displaying the kernel  boot messages on LCD, and then a login screen on LCD should be possible, but what am I missing? is there a documentation for this somewhere?

    thanks for all your answers.

  • Hi Faith,

    Sorry for the delayed response,

    Enable the fbcon, keyboard, virtual console support , and in linux menuconfig as per the following link,

    I got working login console on my VGA display for accessing linux fs commands through external USB keyboard as like your requirement,

     Character devices  --->

    [*]   Support for console on virtual terminal

    USB HID support

    Use the env arg "console=/dev/tty0"

    Ex:

    setenv bootargs mem=32M console=tty0,115200n8 ip=dhcp nfsroot=10.100.1.106:/home/titus/OMAP-L138-LCDK/ti-sdk-omapl138-lcdk-01.00.00/filesystem root=/dev/nfs rw rootwait

    Refer the below link,

    http://blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:fbcon

    I hope that you get succeed now.

  • Thanks a lot, Titus. Unfortunately, still no luck.

    Here is console entries in my .config, which is set by setting 'Device drivers > Character devices > Virtual Terminal' on, and 'Device drivers > Graphics support > Console display driver support > Framebuffer console support' on.

    CONFIG_CONSOLE_TRANSLATIONS=y
    CONFIG_VT_CONSOLE=y
    CONFIG_VT_CONSOLE_SLEEP=y
    CONFIG_HW_CONSOLE=y
    CONFIG_VT_HW_CONSOLE_BINDING=y
    CONFIG_SERIAL_CORE_CONSOLE=y
    CONFIG_SERIAL_OMAP_CONSOLE=y
    # Console display driver support
    CONFIG_DUMMY_CONSOLE=y
    CONFIG_FRAMEBUFFER_CONSOLE=y
    CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y

    After setting console to tty0 (also tried with /dev/tty0, fb0, /dev/fb0), still kernel boot messages are not visible under the penguin logo on the LCD. The logged messages are as following. I wonder if I should disable another option in menuconfig:

  • Hi,

    Please attach your complete bootup logs and not a simple text paste.

    PFA of my .config and inittab file from filesystem,

    Try NFS filesystem for mounting to test, because need to modify the inittab files also,

    0250.dot_config_omap138lcdk.txt

    0028.inittab.txt

  • 6366.kernel.arch.arm.configs.tisdk_am335x-evm_defconfig.txt

    7888.rootfs.etc.inittab.txt

    8814.rootfs.var.log.messages.txt

    7411.boot.uEnv.txt

    here are the related files, from a fresh build. (the build environment is not set up for tftp/nfs boot at the moment, so, using sd card)

  • Hi,

    [    0.000000] Console: colour dummy device 80x30
    [    0.000000] console [tty0] enabled

    It seems to be, It enabled the fb console driver,

    I think that you are getting  "console login" option on LCD display after some time.

    Use attached inittab file in your SD card filesystem (boot the board through single user mode ie  init 1).

    8585.inittab_faith.txt

  • Hi Faith,

    Try this bootargs,

    setenv bootargs mem=32M console=tty0 console=ttyS2,115200 ip=dhcp nfsroot=10.100.1.106:/home/iyshwarya/OMAP-L138-LCDK/ti-sdk-omapl138-lcdk-01.00.00/filesystem root=/dev/nfs rw rootwait

    Change it your appropriate console,

    I think,

    console=tty0 console=ttyS2,115200 to console=tty0 console=ttyO0,115200

    Please let us know the status.

  • with the inittab booting to runlevel 1, only the penguin appears again.

    i'll check with the update to consoles argument.

  • Any news from this issue?
  • with ti-sdk-am335x-evm-07.00.00.00, we did not observe the problem.
  • Hello Larbi,

    Since this is such an old thread, would you be willing to create a new thread, detail the issue and circumstances you are observing, and what you are wanting to solve.  I think it will be much more effective than a general inquiry to a long and old thread.

    ~Leonard  

  • Ok good.
    Can you give me your config: kernel cmdline, inittab and kernel config?
  • Ok LeonardEllis.
    I will try with an other sdk and report if there is a bug.
  • console=ttyO1,115200n8 consoleblank=0 vram=50M root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait

    the defconfig is minor changes on top of the tisdk_am335x_defconfig.

    1004.defconfig.txt

    the start-up script is updated a bit in our case, so, inittab uses rc.sh instead:
