[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

What did you change for your port?

^^^^^^^^^^^

For example, where is this address coming from?

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?
