Dear support,
We would like to detect at boot if the CPU watchdog kicked (/dev/watchdog0). According to this
watchdog article
a kernel message should appear when this happens.
[ 4.447307] tegra_wdt tegra_wdt: last reset due to watchdog timeout
When the watchdog kicked, this message is not shown unfortunately. The article also states there is a Toradex custom driver used. Where is this driver implemented, so I can very we do have this present. Or is there another way to find out if the watchdog triggered the reset?
hello @markvdputten and Welcome to the Community!
Could you provide the version of the Hardware and Software of your module? Which carrier Board are you using?
I reproduced your issue on using dev/watchdog1
on Bsp 2.7b4 and Bsp 2.8:
In Bsp 2.8, there is a message showing the ResetReason: WDG if the reset is due to Watchdog.
For the kernel message, I also did not see anything. Thus, we will look into this issue and come back soon to you.
Best regards,
Jaski
We have a custom main board, and a custom os based on poky with a lot of parts derived from toradex bsp. What I mean to say is that it is not exactly like a Toradex provided BSP, what I am working with.
Knowing if the watchdog kicked, is very valuable information.
If you find anything related I am very interested.
Hi @markvdputten
Currently the watchdog driver for Colibri T30 does not provide any Information if the Reset was done by Watchdog. However you get this Information for U-Boot. So you just need to pass this Information from U-Boot to Linux kernel.
Best regards,
