Hi CAI

most probably board hangs, one can check with oscilloscope power supplies

and clocks using recommendations in i.MX6 System Development User’s Guide

https://www.nxp.com/docs/en/user-guide/IMX6DQ6SDLHDG.pdf

Also one can try to test with simple ddr_test.c with jtag using bare metal sdk

(zip can be found on https://community.nxp.com/thread/432859 )

Best regards
igor
