Nano boot failed

Hi,
my nano module failed to startup,The phenomenon is as follows:


CH1:5V,CH2:POWER_EN,CH3:RST,CH4:PMIC_BBAT;
log:
error.log (17.9 KB)

during my debug,i found if i change zhe Carrier Board Supplies same as power_en,my board boot success,then,zhe module can success all the time.
now,We have the following questions:
1、why i change the Carrier Board Supplies time,the RST levle change from 3.3 to 1.8V?
2、why the module success once,can boot all the time?
