Hi, jyijyi

(Sorry this is SFDC for only our account)
According to the above SFDC, you said that module was reboot both telecom core and modem core if the module was hang-up.
I think the recovery sequence of legato and yocto distribution in that case.
“Yocto freezes” means to be supposed such module hang-up situation.
I would like to know which areas inside of WP can be recovered automatically and whether legato API watch is worked in this module hang-up situation.
