Your first mail mentions a custom board, but this indicates "TQMa6Q
on MBa6x", so which is it?
Please note that there are two different module variants, imx6qdl-tqma6a.dtsi 
and imx6qdl-tqma6b.dtsi. They deal with i.MX6's ERR006687 differently.
Package drop without any load somewhat indicates this issue.

Best regards,
Alexander
