Re: Some version different

 I want to ask some questions about the different version:
  1. The linuxppc_2_4_devel   and   the linux-2.4.25.tar.bz2 in ELDK
3.1.1 package

THe traball is a snapshot from the linuxppc_2_4_devel CVS  tree  (for
ELDK  3.1.1  the  date  of  the  snapshot  is  2005-03-06  or CVS tag
LABEL_2005_03_06_0100).

  2.  The ppcboot 0.9.2 compiled with mvstia devrock   and    the
U-Boot 1.1.2 compiled  with ELDK

PPCBoot 0.9.2 and U-Boot 1.1.2 are about 4 years apart. This is  like
comparing Linux kernel versions 2.0 with 2.6 ....

  Does the kernel freeze at "transferring control to linux" could be
these different versions? 

Both versions were perfectly  capable  of  booting  a  working  Linux
kernel. I don't know the MV toolchain, but I guess it's working fine,
too.  So my guess is that it's your port of the Linux kernel which is
broken.

  1 why I configed the kernel with CONFIG_HD860 in "make menuconfig" but
the code in CONFIG_HD860 
     isn't compiled at all ! What's the perhaps reasons? I checked the

Your port of the Linux kernel is broken.  Probably  you  made  errors
when changing the configure scripts and/or Makefiles.

   2  How to get board info "struct bd_info" in init/main.c ? I want to
use printf of bd_t->bi_mon_fnc->printf() to 

You cannot do that. It does not work.

       print some string on console. Does it possible? But the code is
only in head_8xx.S, How to get the bd* data in 

The _res pointer can be used for that; see the existing driver sources.

       main.c ? Some board use get_board_info(). But how can I use it? 

This depends on how your hardware and your port of Linux support such
a feature. I cannot answer such a question.
