How do you compile it? make xxx_config What is xxx for you? I looked in code but couldn;t find a "SLN Technologies" string ... >> As I saw in your log, it uses the "normal" mtest.

I looked in 1.3.1, so you should add a #define CFG_ALT_MEMTEST 1 >> instead.

Hmm... nothing spring to my mind, just the "standard" things: check your - HRCW - clocks - SDRAM settings bye, Heiko -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
