Re: [U-Boot] U-boot-2012.04 compilation for qemu-mips board

2013-07-01 Thread krishna dwivedi

Hi Wolfgang,

I knew i have to run make qemu_mips_config before make allI am using ELDK
5.3 toolchain and compiling u-boot recipe came as a part of ELDK..But in
yocto environment,we use bitbake instead of make.I already tried make:
[unknown@h229 build]$ make qemu_mips_config
make: *** No rule to make target `qemu_mips_config'.  Stop.

I guess i need command analogous to make qemu_mips_config to run before
bitbake u-boot.

Krishna

Hi All,

Hope everyone is doing great:)

I am trying to build U-boot:2013-04.But running into this error:
mips64-nlm-elf-ld: arch/mips/cpu/mips64/start.o: relocation (null) against
`board_init_f' can not be used when making a shared object; recompile with
-fPIC
arch/mips/cpu/mips64/start.o: could not read symbols: Bad value.


Initially,In file arch/mips/config.mk,I commented the flag:
#LDFLAGS_FINAL   +=  -pie
This error resolved.But after relocation of u-boot code,we need this
flag.So i need to uncomment this flag.and again i am running into this
error agian.

Anyone faced this issue earlier.Anyone please provide pointers to resolve
this.

Thanks in advance!!

Re: [U-Boot] Porting U-boot-2013-04 to sdk for mips board

2013-06-13 Thread krishna dwivedi

Hi All,

In mips,i dont see the .reloc section in u-boot.lds.But in other
architechtures(like ppc),I see in u-boot.lds:

.reloc   :
  {
PROVIDE(_GOT2_TABLE_ = .);
KEEP(*(.got2))
KEEP(*(.got))
PROVIDE(_GLOBAL_OFFSET_TABLE_ = . + 4);
_FIXUP_TABLE_ = .;
KEEP(*(.fixup))
  }
  __got2_entries = ((_GLOBAL_OFFSET_TABLE_ - _GOT2_TABLE_) >> 2) - 1;
  __fixup_entries = (. - _FIXUP_TABLE_) >> 2;


1)Can anyone please let me know,if we dont need to add .reloc section in
u-boot.lds for MIPS processor?

2)I am newbie to u-boot,Please anyone provide me pointers what are the
things i need to do lowlevel_init for my mips processor.



Regards,
Krishna

[U-Boot] Porting U-boot-2013-04 to sdk for mips board

2013-06-13 Thread krishna dwivedi

Hi,

I am trying to port the u-boot2013:04 to sdk.During compilation,I am
running into error:*Undefined reference to _GLOBAL_OFFSET_TABLE*.I checked
in u-boot.lds file thr is no definition of _GLOBAL_OFFSET_TABLE.I have
added this piece of code in u-boot.lds:
.reloc :
{
  KEEP(*(.got))
   PROVIDE(_GLOBAL_OFFSET_TABLE_ = . + 4);
}

In addition,i see reference of GLOBAL_OFFSET_TABLE.But it is not defined in
any file and even linker script.
Can anyone please confirm,if this is common issue in u-boot version 2013:04.

Regards,
krishna
