Hey

my teensy have started to shut it self off when ever i put the micro-USB in the Teensy. i can se that i gets 3.3V in a short while and then the K7(PMIC_ON_REQ) pin on the uC will go low, disabling the 3V3 voltage supply.

is this hardware or software error ? is it something i can fix ?
 
Do you have anything connected to the On/Off pin?

While software can initiate power off mode, pulling that On/Off pin low is the normal way the power off mode is triggered.
