TK1 system crash , no console login appear

reference TK1 EVM board to design my board.Now I can flash the rootfs into emmc.But system startup ,HDMI output log info , after roughly 10s, the HDMI output nothing, then wait for several times, still no the system console login appear. test for 5 chips still not working.So ask for help. my ddr is Samsung K4B8G1646Q-MYKO 4GB ,1GB per chip, different from EVM board .ddr layout is not changed. CPU is differnt, too. CPU info is CD575M-A1. Ask for help!!!

It sounds like a common problem which is video only. Can you ping the TK1? Can you log in via ssh? Do you have serial console available?

Don’t have a serial console available.So First I try to make debug console available.

Do you have any log info of flash and power up?
