Hello.
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.
David.

Hello,
Please check carefully Your design regarding the Checklist and bring-up issues.
Please refer to Chapter 2 (Design Checklist0 and Chapter 8 (Avoiding Board
Bring-up Problems) of : “Hardware Development Guide for i.MX 6 …”
http://cache.freescale.com/files/32bit/doc/user_guide/IMX6DQ6SDLHDG.pdf
Note, recent design checklist may be found at
https://community.freescale.com/docs/DOC-93819
Next, please check memory, using the stress tool :
i.MX6/7 DDR Stress Test Tool V2.40
If all is OK, You need to apply debugging Linux via JTAG.
Have a great day,
Yuri
