My jetson xavier AGX reboots about once every few days. “### PMC reset source:” in syslog is recorded as “TEGRA_BCCPLEX_WATCHDOG”.
By the way, when watchdog is used by the following command, it seems that “TEGRA_SOFTWARE_RESET” is recorded in “### PMC reset source:”.
echo 1> / dev / watchdog
So I have a question.
1: When is it rebooting with TEGRA_BCCPLEX_WATCHDOG?
2: How can I avoid it?
note)
a} The version of SDK I’m using is:
R32 (release), REVISION: 3.1, GCID: 18186506, BOARD: t186ref, EABI: aarch64, DATE: Tue Dec 10 07:03:07 UTC 2019
b} There is no clue in the serial console log, and suddenly a reboot occurs as shown below.
W> RATCHET: MB1 binary ratchet value 4 is too large than ratchet level 2 from HW fuses.
I> MB1 (prd-version: 1.5.1.2-t194-41334769-9ec1833d)
If the cpu gets hang over timeout, watchdog will trigger this reboot and next reboot reason will be TEGRA_BCCPLEX_WATCHDOG.
As for why the cpu would hang may have lots of reasons. Better using the uart console to monitor the log. For example, what are the last few lines running before the reboot.
Yes. I always run 1080p recording and playback applications on gstreamer.
It looks like there is no bad behavior in the logs on gstreamer.
Does this condition occur due to malfunction of encoder and decoder?
