Our product most work scena is 24-hours environment。
To ensure the stability of the device：
1、the nx itself have a Mechanism of abnormal situation，such as described on the NX datasheet:[If the module needs to request a shutdown event in the case of thermal,software,or under-voltage events,it will assert SHUTDOWN_REQ*]。
1.1、about the thermel，After the experiment，when above 94.5℃，NX assert SHUTDOWN_REQ* to LOW level.then shutdown。when high temperature disappear，It can only be restarted manually，Unable to restart automatically。
1.2、about the software.
a、When the Ubuntu does not work，the NX can be restarat automatically ?
b、the Instability caused by application software，system does not work，the NX can be restarat automatically ?
1、our target is，the NX can restart automatically。please tell us if has a good methord to realize it。
2、we find a information “FUSE_RESERVED_SW[23:0] bit enable watchdog”，this is How to work。
