[U-Boot] MAKEALL ml507_flash return "Not enough room forprogramheaders" error

[Benny Chen]

Hi Guys,

The above error message was resolved by using the ELDK cross compiler.
Previously I was using Xilinxs powerpc-eabi-xx cross compiler to build
U-Boot. 

Cheers,
Benny

Hi Ricardo,

Thanks for helping with this issue.  My real option is to do a long jump
to the _start code.   However, I am not familiar with the PPC assembler
hence, I am not able to get the longcall working.

_start is written in assembler in cpu/ppc_4xx/start.S therefore, I need
to do a longcall from assembler which I am not sure how to do.  Could
you please help advise on how I can do a longcall in assembler?

Further, investigation I found that the other option is to do a function
pointer call to _start.  When written in C this should force the use of
the CTR register which is 32-bit to hold the _start address.  But I
don't know how to do this in assembler.  If you have any idea on this it
would be much appreciated.


Thanks once again mate.

Regards,
Benny

Hello Benny

  Maybe if you move your _start to the booptg section you will solve
your problem.... or you can also modify the jump to be a long jump.


              Best regards
