I attempted to execute a cmake build and rebooted, but I still encountered an infinite login loop.
To resolve this, I reinstalled the display manager and chose gdm3.
However, this time the keyboard and mouse input were not working.
I attempted to access the tty terminal, but I couldn’t because the keyboard is not working
What should I do?
What’s this one about? What kind of program are you building?
What L4T/JetPack version are you using?
Is it a DevKit or a custom board?
I am using an NVIDIA AGX Xavier. It’s a Dev Kit.
The basic environment is as follows:
OS: Ubuntu 20.04
After building a C++ based program and rebooting, I fell into an infinite login loop.
After resolving this error by reinstalling gdm3, I encountered a problem where keyboard input was not working at the login screen.
Then if you login to the system via serial console, plug an unplug your mouse/keyboard, are they detected with dmesg?
I currently do not know how to connect to the serial console.
I do not have a micro USB-B cable. Is there another way?
Have you tried unplugging and plugging the mouse/keyboard at the login screen?
Yes, I just tried that, but it didn’t work.
Is there no other way besides reinstalling Jetpack?
If you don’t have access to serial console, then the only thing I can suggest is re-flashing the device.
Thank you. It was very helpful!
Incidentally, the micro-OTG USB connector to the left of the 40-pin header on the AGX Xavier dev kit is the serial console for that model. You’d just plug in the micro-B USB to that connector, watch “
dmesg --follow” on the Linux host PC, and plug in the USB-A side to the host PC (the log message should show the names of the serial devices). The first serial device is named when running a serial console program on the host PC with speed 115200, 8 bits, no parity, and one stop bit.
Thank you for the additional information! On Windows, I opened a total of four ports by connecting via micro-USB ctype for serial connection. I tried opening the serial console with the settings you mentioned, but there was no response. Does it not work on Windows?
I don’t now if it is COM5 or something else. Serial console does work from Windows, but finding the right setup might be a bit more frustrating. You might try with all of the COM ports.
