[U-Boot] DM9000 on 2011.03

Hi, Guys

I am trying to run u-boot-2011.03 on Mini2440 (samsung S3c2440), now uboot is running,

I have some trouble with network chip dm9000 , Uboot can detect the chip "net: dm9000"

when doing ping, it keeps showing "raise:signal # 8 caught"

if comment it out. it complains: “could not establish link” if comment out this in dm9000_init

#if 0 i = 0; while (!(phy_read(1) & 0x20)) { /* autonegation complete bit */ udelay(1000); i++; if (i == 10000) { printf("could not establish link "); return 0; } } #endif it just hanging there

any thought? Thanks

Craig
