Dear sean, and others,
I encountered a small problem running linux on the sipeed maix bit from
u-boot.
Every 90 seconds (exactly) after boot it resets, if booted into linux,
unless I disable the watchdog.
This has occurred since this feature was enabled
(e3282b1bbae4e8558c2b85bf27560d12358ed25f)
Although I do not completely understand the watchdog features, it notes
it is set to 60 seconds,
and I am convinced that the point is not to reset every X seconds.
Especially because this is enabled by default.
I have not really found a good workaround besides disabling the WDT at
runtime which is cumbersome.
Is this expected behavior? And if so, how do I disable this feature at
compile time?
Kind regards,
Jaap Aarts

Do you have CONFIG_DW_WATCHDOG enabled in your kernel?
