* Environment board : IBM Walnut(IBM PowerPC 405GP Rev. D) bootloader : u-boot 0.4.0 linux kernel : Montavista Linux Preview Kit 3.0 modification -> mkimage
"Real time clock seems stuck!" messeage comes out but real stuck position is on sti() in _start_kernel() (init/main.c)
I tested in OpenBIOS bootloader using same kernel source and it worked fine...
what do i do for u-boot and kernel setting ??
please, help me. refer to following rom monitor messeage for checking...
