This is also present in the gumdroid 2.6.32 kernel, I swapped
to the TWL watchdog as well. I believe it has something to do with the
WaterStorm or the version of MLO in the NAND, but I am unsure.
I am upgrading my kernel to 2.6.39 for my Android port, if I
get that working, I will be checking the watchdog and if the OMAP watchdog works
I'll let you know.
Update: disabling the OMAP
watchdog and enabling the TWL4030 watchdog does work; the TWL wdt is able to
reboot the COM all the way.
So the question is: what is missing in the

I have a
couple of questions on the watchdog timer. I am working on Rowboat kernel
2.6.37, running on a WaterStorm COM/Chestnut43.
1. The default config
has the following options enabled (and I see this in current Sakoman configs
the omap and twl4030 watchdog drivers register with minor number
WATCHDOG_MINOR. The OMAP driver loads first, and since a device with that
minor is already registered, the loading of the TWL4030 watchdog always
twl4030_wdt twl4030_wdt: Failed to register misc device :
twl4030_wdt: probe of twl4030_wdt failed with error
What is the intent here? Surely both watchdog drivers cannot
coexist unless the minor numbers are changed? Should only one of the two be
enabled by default?
2. I tried running the demo here with the
omap watchdog (which is the one that gets loaded first):
sure enough, if the watchdog isn't kicked, the COM reboots... or rather,
tries to. The LCD goes gray and gets bands on it which makes it seem like
the machine is trying to reboot- but the reboot doesn't complete. I have to
manually press the RESET button on the Chestnut board to reboot. Why is
this? Isn't the OMAP watchdog driver capable of rebooting the COM? Or is
some other functionality needed for that? I had read on this list sometime back that there is
an issue with the OMAP watchdog driver w.r.t. the DM37x CPUs on the Storm
series COMs- is that true? I have not tried disabling the OMAP watchdog and
enabling the one on the TWL yet.
