Hi freescale:

android :i.MX M6.0.1_1.0.0-ga

uboot :2015.04

kernel:3.14.52

 

I'm currently running android i.MX M6.0.1_1.0.0-ga mfgtool BootStrap state and I'm having the following issue. The boot suddenly freezes with the message "random: nonblocking pool is initialized"

 

random: nonblocking pool is initialized
