[ECOS] build Tx39xx program

["adon at walkersun" <adon at walkersun dot com>]

Hi all,

 

 

    Now I could build all the tool kits under win2000 with cygwin. Those tools are include binutils, gcc, insoghtand newlib.

 

    And I got a board from Toshiba brach which is Tx39xx MIPS CPU contain sygmon on the board.

 

    Now I wrote a very simple program to test entire system. as following

 

============================================

 

#include <stdio.h>   

 

void test(void)

{

  printf("in sub...\n");

}

 

int main(void)

{

  printf("Hi, it's work...\n");

  test();

  return NULL;

}

 

============================================

 

And the following are the coomands which  i do

 

============================================

 

mips-tx39-elf-gcc -c -g -O2 main.c

mips-tx39-elf-ld crt0.o crtbegin.o main.o -T jmr3904.ld

 

============================================

 

The crt0.o, crtbegin.o and the libraries files like libc.a libgcc.a libjmr3904.a libdve.a, jmr3904.ld are come while I build the tool chain.

 

 While I use the libjmr3904.a the linker always prompt me "connot find label get_mem_info", so I could get the download file. but if I replace the libjmr3904.a with libdve.a then the link could build the download file. But while I use the objdump, I could find the get_mem_info in the libjmr3904.a. So why I cannot build the download file while I use libjmr3904.a??

 

 

Are there anybody could help me???  Thanks
