[U-Boot-Users] u-boot compilation problem

[Pradip Singh]

Hi all,
 
  I am porting the U-boot to my custom board which  is arm based. While building the u-boot i get the following compilation error.
 
armv5b-softfloat-linux-gcc -g  -Os   -fno-strict-aliasing  -fno-common -ffixed-r8 -msoft-float -D__KERNEL__ -DTEXT_BASE=0x00780000 -I/root/isl/heron_old/u-boot-1.1.1/include -fno-builtin -ffreestanding -nostdinc -isystem /opt/crosstool/armv5b-softfloat-linux/gcc-3.4.1-glibc-2.3.3/lib/gcc/armv5b-softfloat-linux/3.4.1/include -pipe  -DCONFIG_ARM -D__ARM__ -mapcs-32 -march=armv5te -mbig-endian -Wall

Any clue what this problem can Be?
 
Thanks and regards,

An undefined reference to printf?
Sometimes compiler errors _do_ give useful messages.

It looks to me you are not linking with the file where 'printf' is
implemented in.

quick-n-dirty:
put the following in your file >:)
#define printf(args...)  do { } while(0)

What did you change for your port?

For example, where is this address coming from?

> Any clue what this problem can Be?

Since it compiles find  with  working  toolchains  for  the  existing
boards the problem is either in your modifications to the code and/or
in your toolchain.

Can you compile your modified code using a working toolchain (like ELDK 3.1) ?

Can you compile other ARM boards using your own toolchain?

[U-Boot-Users] u-boot compilation problem

[Pradip Singh]

Hi,
 
  Ya I agree that address is wrong 0x000007fc0. Actually in the U-boot example directory Makefile there is a macro LOAD_ADDR. I wanted the hellow_world program to load at address 0x00007fc0. Hence I thought that by changing this macro i may be able to achive my objective. Is my asumption correct? I am relocating the u-boot code at address 0x0078000. Also When i am going through the U-boot examples directory Makfile I find that hello_world is not getting linked  with libcommon.a which is having this printf. So i tried also linking with libcommon.a but it seems it has a lot of dipendencies on other libraries. I donot suspect the tool chain becouse the U-boot builds and also runs fine when i remove the compilation of example directory. I want to compile this hello world example to see that i am able to run a program from memory using go command. 
 
Also I want the printf in Hello_world so that i can see some output on my console.
thanks and regards,
Pradip

Are you sure that there is free memory at this  address??  What  does

Please don;t try to do thinks which you don't understand.  Standalone
applications do not link against the U-boot libraries. Please RTFM.

For a start, read doc/README.standalone

Why don't you just leave the code as is? It is working fine  in  it's
current state. Your modifications just broke it.

even better
#define printf() 
(replace by nothing)
