Initramfs: chip reboots after 30s seconds

Bumsik Kim

Hi,

I'm playing around initramfs shell using initramfs-framework in Yocto environment.

I found that the chip abruptly reboots after some time (I think it's around 30 seconds) if the initramfs doesn't fully boot the system by entering systemd.

I think it's because of kind of system timer like watchdog, but I'm not sure.

Anyone know what's causing force reboot and how to workaround it? (disable, extending the timer, or implementing timer handler etc.)

Hi,

I figured out the solution by using busybox's watchdog command as described in the wiki article. Thank you very much!​
