I do GPU test on our board, It's base on SABRESD Board.But we change ddr3 to lpddr2. And using 32 bit single channel mode with 2 chip selects, 512B pre channel. We can pass ddr_stress_tester more then 2 hours  (ver2.52).

And we also pass classic tset (without gpu) more then 4 hours. But when we test with GPU, the system will hang in 5 minutes (always less then 2 minutes), and without any logs. 


We check all power domains are normally... How do i to verify to debug ? Thanks!
