Can anyone tell me if it is a bug of the ELDK4.0?

2006-06-28 Thread Denny 
Hi,
 
 I failed to compile the uboot on my 440GP platform, I set the compile 
switch as -m440 -mcpu=440,

  But the interest thing is when I change the switch to -m405 -mcpu=440, 
I can compile my uboot successfully, why?
 
  Also I find all the instructions are existed both in user manual of 
PPC_405 and PPC440.

Don't do this, then. The  ELDK  will  automatically  set  approproate
compiler  options  as  needed,  depending  on  your  setting  of  the
CROSS_COMPILE variable.

All this is documented in the manual.

Just follow the instructions.


Best regards,
