Hi,
thanks for that hint. Ok, i also tried that before. I copied
write from write.c:
int _DEFUN (write, (fd, buf, nbytes), int fd _AND char *buf _AND int nbytes) {
int i;
outbyte('j');
for (i = 0; i < nbytes; i++) {
if (*(buf + i) == '\n') outbyte ('\r');
outbyte (*(buf + i));
}
return nbytes;
}
If i call it directly from main() i can see an output:
write(1, "Hi world\n", 9); // works fine
But printf("Hello world\n") does not work at all.
I've also generated a complete listing of my ELF file:
v850e-unknown-elf-objdump -D file.elf >file.list
In there i can see that there is a second __write. Also when
i overwrite this one i don't get no output.
I've also overwritten some other functions and output a character
to see if they get called. None of them does. Here's a list:
close, fstat, getpid, isatty, kill, lseek, open, read, stat, unlink
and write.
I wonder if i need to initialise them somehow?
Best regards,
Torsten.
