i did set TEXT_BASE = 0xFFF00000 i changed the makefile to pick the appropriate Cross Compiler. ifndef CROSS_COMPILE ifeq ($(HOSTARCH),ppc) CROSS_COMPILE = else ## #ifeq ($(CPU),mpc8xx) ## CROSS_COMPILE = ppc_8xx- ## #endif ## #ifeq ($(CPU),ppc4xx) ## #CROSS_COMPILE = ppc_4xx- ## #endif ## #ifeq ($(CPU),mpc824x) ## #CROSS_COMPILE = ppc_82xx- ## #endif ifeq ($(CPU),mpc8260) CROSS_COMPILE = ppc_82xx- endif ## #ifeq ($(CPU),74xx_7xx) ## #CROSS_COMPILE = ppc_74xx-) ## #endif ##ifeq ($(ARCH),ppc) ##CROSS_COMPILE = ppc_8xx- ##endif ##ifeq ($(ARCH),arm) ##CROSS_COMPILE = arm_920TDI- endif endif ##endif > Type "reset" and "info" and check where the PC is pointing to.

Also, please > note that thge reset entry point is at offset 0x100, so "go > 0xfff00000" is definitely wrong - try "go 0xfff00100" instead. reset info (PC: 0xfff00100) go (it is actually running now.. but im not sure if it is running properly) halt (PC: 0x03fdc420) and.. this is what is at md 0xfff00000 fff00000 : 10101010 10101010 40404040 40404040 ........@@@@@@@@ fff00010 : 02020202 02020202 45454545 45454545 ........EEEEEEEE fff00020 : 00000000 00000000 00000000 00000000 ................ fff00030 : 00000000 00000000 00000000 00000000 ................ fff00040 : 00000000 00000000 00000000 00000000 ................ fff00050 : 00000000 00000000 00000000 00000000 ................ fff00060 : 00000000 00000000 00000000 00000000 ................ fff00070 : 00000000 00000000 00000000 00000000 ................ fff00080 : 00000000 00000000 00000000 00000000 ................ fff00090 : 00000000 00000000 00000000 00000000 ................ fff000a0 : 00000000 00000000 00000000 00000000 ................ fff000b0 : 00000000 00000000 00000000 00000000 ................ fff000c0 : 00000000 00000000 00000000 00000000 ................ fff000d0 : 00000000 00000000 00000000 00000000 ................ fff000e0 : 00000000 00000000 00000000 00000000 ................ fff000f0 : 00000000 00000000 00000000 00000000 ................ the output of the target board is just garbage characters now.
