I used mtest in u-boot and got the following results: => mtest Pattern 00000000 Writing... ^H^H^H^H^H^H^H^H^H^HReading... Mem error @ 0xA3EDBAEC: found A3EDBB0C, expected 00F76EBB Mem error @ 0xA3EDBAF0: found A3EDBAFC, expected 00F76EBC Mem error @ 0xA3EDBAF4: found A3F1227C, expected 00F76EBD [...] Mem error @ 0xA3EDBC50: found A3EDBC48, expected 00F76F14 Mem error @ 0xA3EDBC54: found 00F76F14, expected 00F76F15 Pattern FFFFFFFF Writing... ^H^H^H^H^H^H^H^H^H^H? ^^^^^^ HANG! Memory test finds some errors during write/read 0x00000000 pattern and it hangs before it can read back 0xFFFFFFFF. I suppose this is not the expected board behaviour. Has anybody any idea what is going on ? Is this a config error ? (I should probably check the setting in configs/board.h) regards, himba -- ..because under Linux "if something is possible in principle, then it is already implemented or somebody is working on it". --LKI
