IMX6 Crash before linux prompt

Question asked by David Ziv on Nov 30, 2015
Latest reply on Dec 11, 2015 by Yuri Muhin

My board based on IMX6-SOLO


I have JLink connection, for debug

at this point "INIT: version 2.88 booting" I have noticed that the processor got an exception, and the system try to reboot  (runlevel=5)


Any idea what is this message mean? or what might cause the exception?


Appreciate any suggestions.
