Hi all, I am using uboot mtest command like this to test my DDRAM. $mtest 0x80000000 0x80e00000 My memory runs at 67Mhz clock. And uboot entry point is 0x80e80000. Can anybody tell me how much time this test will take to complete??(on my board this test is still running, i started it 2 hour ago) Best regards Arun
