[U-Boot-Users] does this situation can assert to be a hardware problem?

[zhuzhenhua]

in the u-boot, when run into board_init_r(lib_mips/board.c), sometimes
it stop at the call of mem_malloc_init, sometimes it stop at the call
of env_relocate.
does it means it maybe caused by hardware or uncorrect sdram init?, it
can not be the software ploblem of the board.c file?
when i used the bdi2000 to debug in, i found at the call of mem_malloc_init
"lw t9,8(gp)"
, if i set a breadpoint at
"addiu	t9,t9,1552", the t9 is not the correct value ,but in gp+8 is
still a correct value

and if a set a breakpoint before "lw t9,8(gp)" at anywhere after
in_ram, the t9 can get the
correct value, so it can run the mem_malloc_init, and run to hang at
env_relocate


as follow is the dissamble file
bfc00b80 <board_init_r>:
......
bfc00c90:	8f990008 	lw	t9,8(gp)   //to call mem_malloc_init
bfc00c94:	00000000 	nop
bfc00c98:	27390610 	addiu	t9,t9,1552
bfc00c9c:	0320f809 	jalr	t9
bfc00ca0:	00000000 	nop



as follow is the  printf info of two different reset and go situation
