JP4.2.1 Change serial console

Hello,

I have a custom carrier board that does not pin-out the ttyS0 for serial console, but ttyS2 is available. Through modification of the device tree and other files I got u-boot to log to ttyS2, but the serial output stops once the kernel starts. Any advice what I might have missed for the kernel to not have changed its console port?

I got a lot of my ideas from this thread: https://devtalk.nvidia.com/default/topic/1025894/jetson-tx2/uart1-acts-as-default-debug-port-on-tx2-r28-1/post/5220368/#5220368

And I did a bunch of searching the source files for ttyS0 and replacing with ttyS2 where it seemed to make sense.

Serial boot messages:

hello ahuska,

had you also modify the the default settings by changing the console?

Hi JerryChang,

I’m not familiar with what or where the default settings are, can you tell me?

Thank you

hello ahuska,

please refer to below,

<i>$OUT/Linux_for_Tegra/p2771-0000.conf.common</i>

CMDLINE_ADD="console=<b>ttyS2</b>,115200n8 console=tty1 OS=l4t fbcon=map:0 net.ifnames=0";

im also having same issue with uart2 , i did modifications in following files

tegra186-mb1-bct-misc-si-l4t.cfg
dts
p2771-0000.conf.common

im getting only u-boot prints. neither im getting mb1 prints nor linux boot prints

please help with the issue

hello ahuska,

suggest you should also contact with carrier board vendor,
please check if they had kernel changes to unregistered the console.
thanks

[    0.018382] bootconsole [uart8250] disabled

i have my custom carrier card on which tx2i module is mounted, whatever vendor provided sdk/ kernel source only i used to modify and flash it.

i didn’t get you are telling. please elaborate

hello shrinathchoudhary,

you may review the kernel sources, to check if there’s function call to disable that intentionally.
for example, unregister_console()

do i have to build the image once modification is done??

when i searched in kernel-souurce
at drivers/tty/serial/serial_core.c i found this but i donno which uport it is disabling

/*
         * If the port is used as a console, unregister it
         */
        if (uart_console(uport))
                unregister_console(uport->cons);

Hi JerryChang,

After a couple weeks of other work I am back on this issue.

I created my own carrier board and have made minor modifications to the JP4.2.1 source and rootfs to adapt. Since my board does not have ttyS0 I am trying to modify the DT, kernel source, and flash scripts to enable ttyS2 as the console. I have not disabled the console registration in the uart or printk source.

As noted before I do get uboot messages on ttyS2 so the hardware is working. It is the kernel output and single-user console that I need to get working.

I have experimented with changing the line
CMDLINE_ADD=“console=ttyS2,115200n8 console=tty0 fbcon=map:0 net.ifnames=0”;
to various things like
CMDLINE_ADD=“console=ttyS2,115200n8 console=tty1 fbcon=map:0 net.ifnames=0”;
CMDLINE_ADD=“console=ttyS2,115200n8 console=tty2 fbcon=map:0 net.ifnames=0”;
CMDLINE_ADD=“console=ttyS2,115200n8 console=ttyS0 fbcon=map:0 net.ifnames=0”;
CMDLINE_ADD=“console=ttyS2,115200n8 console=ttyS2 fbcon=map:0 net.ifnames=0”;

Interestingly, when I use ‘console=ttyS2’ or even ‘console=ttyS0’ I receive the first couple seconds of kernel boot logs on ttyS2 but then the Jetson freezes and reboots after a while. However, it does not always freeze at the same point in the boot process, and it freezes in the middle of transmitting a line of text, so the crash is very hard to diagnose. Sample ttyS2 data received in this case:

Maybe it is completely invalid for me to try ttyS*, but it is the only thing that is showing any functionality.

Can you help me any further?

Thank you,
Andy

hello ahuska,

we’re having solution for similar issues.
could you please check Topic 1058766 for the steps to disable nvgetty and warm-reboot the device.
thanks

Hi JerryChang,

I tried that with various configurations of the cmdline settings, including exactly the ones in the link, and it did not make a difference. Maybe the issue is different between TX1 and TX2.

Andy
