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.


best regards
