i use my imx6sll customized board with pfuze100
and because i have not add the reset ic,I suspend the wdog_b pin.
i check the source, and try to modify the dts.
delete the "fsl,ext-reset-output".
now i use the watchdog,when time out, it will reset only once.
but next time ,when time out, the system can not reset. it seems that the system halted(nothing i can do but power on again)...
it can reset normally in the evaluation BSP.
I wonder this case is because of not adding the reset circuit so that system can not work stablely?
or i do not configure the kernel correctly?
pls give me some advice.
