imx6ul Log information

[jieh朱]

Hello there
I use imx6ul kernel version is linux4.14.78. I view the system log
# cat /var/log/syslog
He can only save the information of the last startup. The previous log information cannot be saved.
How can I modify it. He can save more information
I checked /etc/syslog.conf and I didn't see any changes

Hi  jiehuai zhu,

You can use journaling as described in below link (you might need to preserve time else logs will be overwritten):

Also, if you want to save syslog at reboot you can use:

crontab -e

@reboot sudo cat /var/log/syslog >> /home/root/syslog
