[U-Boot-Users] Linking problem on new port

[Richard Danter <richard.danter@ntlworld.com>]

Hi all,

I have been using U-Boot for a while, but this is the first time I have 
tried to port it to a new board myself, so please consider me a newbie!

I have a problem linking U-Boot for my new board. I know this is my 
fault, I have missed something in the setup, can anyone point out what 
it is that is missed?

The compile stage works, this is what I see when I try to link:

----
ppc_74xx-ld -Bstatic -T 
/usr/home/wb231-le11/Workspace/u-boot/board/ppmc7xx/u-boot.lds -Ttext 
-n $UNDEF_SYM cpu/74xx_7xx/start.o \
                 --start-group lib_generic/libgeneric.a

                 -Map u-boot.map -o u-boot
ppc_74xx-ld: invalid hex number `-n'
----

The $UNDEF_SYM is obviously wrong (I think!).

I am not surprised if I have missed things, so far I have written just a 
skeleton for the board support, even if it links it won't run yet. I 
have been adding things as needed, but I just can't find what is missing 
here. Any suggestions?

I'd like to ask another question too whilst I'm here. I have a single 
bank of Flash running from 0xFFC00000 to 0xFFFFFFFF. I want U-Boot to be 
placed at 0xFFF00000 with the entry point at 0xFFF00100. Am I right to 
set the following? If not, how do I achieve this?

#define CFG_FLASH_BASE   0xFFC00000
#define CFG_MONITOR_BASE 0xFFF00000

Is this related to the problem above?

Many thanks!
