h8クロスgdbでprintf

カテゴリ[h8]

h8クロスgdbのシュミレータ上でprintfを使う

環境は VineLinux4.0 上の binutils-2.16.1, gcc-4.0.3, newlib-1.14.0, gdb-6.5 の組合せ。

$ cat hello.c
#include <stdio.h>

int main()
{
        int i, j;
        for (i = 0; i < 10; i++){
          printf("<%d> Hello World!\n", i);
          j = i + 1;
        }
}

$ h8300-hms-gcc -o hello -g -mh -mn hello.c

$ h8300-hms-gdb hello
