Hi all,

i reply just to close the thread and to help each other that can have similar issues, this since i have seen other boards that can have the same issue.

The issue was related to my custom board, and more properly was that the linker added some other .bss.* variables after __bss_end__ , that of course u-boot was not relocating into sdram. Error was in my board-related u-boot.lds:

WRONG

__bss_start = .; .bss (NOLOAD) : { _sbss = .; *(.sbss) *(.bss) <---- *(COMMON) . = ALIGN(4); _ebss = .; }

CORRECT

__bss_start = .; .bss (NOLOAD) : { _sbss = .; *(.sbss*) *(.bss*) *(COMMON) . = ALIGN(4); _ebss = .; }

regards, angelo

Hi all,

after a recent update and compiling u-boot, bootloader get locked trying to set a global variable, just after sdram relocation.

Exactly, the program lock here:

1529 void mem_malloc_init(ulong start, ulong size) 1530 { 1531 mem_malloc_start = start; <<<---program paralize here

Tracing the variable offset in memory, i have seen this variable is located a little bit outside (higher address) of the total 16M SDRAM memory size.

Investigating further, in the map file, the issue seems to be that u-boot assign a memory space that is:

len = (ulong)&__bss_end__ - CONFIG_SYS_MONITOR_BASE;

But from the map file the variable seems to have an offset greater than __bss_end :

.bss.mem_malloc_start 0xffc159c8 0x4 .bss.mem_malloc_start 0xffc159c8 0x4 common/libcommon.o 0xffc159c8 mem_malloc_start

.....

.bss 0xffc13e00 0x1544 0xffc13e00 _sbss = . *(.sbss) *(.bss) *(COMMON) COMMON 0xffc13e00 0x4 arch/m68k/lib/libm68k.o 0xffc13e00 monitor_flash_len

u-boot.lds has been checked many times, i don't see any issue on it.

I am using this compiler:

m68k-elf-gcc --version m68k-elf-gcc (GCC) 4.2.4 Copyright (C) 2007 Free Software Foundation, Inc.

Any help is really appreciated.

regards, angelo
