trying to get started with watchdog on rpi5. is there any maximum for the value of RebootWatchdogSec on raspberry pi 5? also how do I arrange with systemd that I will tickle the watchdog from cli, e.g., by periodically running a keep-alive command over ssh?
<Hammdist>
sounds like it might be best to write a Cprogram that directly interacts with the watchdog device .. ugh

supposing I set bcm2835_wdt.nowayout=1 as a kernel argument. then I open the watchdog and fail to feed it for a while. reset. does the watchdog timer get disabled on reset or do I have only a limited time to boot and feed it again? the latter would seem to be implied by the systemd way to do things but is it the default?
<Hammdist>
maybe the RebootWatchdogSec parameter is for a software reset not a hardware-induced watchdog reset, which would supposedly clear the watchdog out
<clever>
Hammdist: i think the watchdog is reset by the reset of the soc

some docs indicate that the bootloader may (optionally?) enable the watchdog so that boot failure can be recovered from
