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?
Have this issue been resolved? Any further support needed?
