Hi, I used NX to connect the serial board, and then powered on to start, but there is no detailed startup information, and there is no detailed system information when I use reboot. Is there anything else that needs to be configured for the serial port?
Are you talking about the log directly starts with UEFI log but no prior logs?
Yes, no log information such as boot and kernel is output
Hi luochen52,
Are you using the devkit or custom board?
Could you login to capture dmesg and /var/log/syslog for further check?
Hi, I am using a development kit. After I log in, I use dmesg or cat /var/log/syslog to have log output, but what I want now is to output log information when I power on, or when I reboot When there is also log output. This can help me analyze the problem. I don’t know why when I execute reboot, it will occasionally fail to start. It can only be started when I power on again. Of course, this phenomenon does not happen every time.
Hi,
I feel you are using the wrong port. Are you using micro usb port on jetson to run as serial port?
Are you using the UART pin on jetson side and x86 host on another side?
The jetson uses the pin header serial port, and the other end uses the win 10 system and serial port tools.
Could you refer to the following instruction to use the pins(TXD/RXD/GND) at the side for serial console?
Jetson Xavier NX - Serial Console
Thanks a lot for your answer, it works.
