Do we need a new ddr config file? Someone can config it for me .Thanks a lot!
Perhaps it is just video which is failing. Can you reach the system with ssh? Does serial console work?
A shmoo test needs to be done when change the memory, there is a memory characterize package in download center, you can follow its Appnote to run sanity shmoo and full shmoo, and then fill in the config file with optimized value.
