Coding > Multiboot problem

#25958 - ProblemBaby - Wed Sep 01, 2004 9:28 pm

My Multiboot code works nice when I compile the master as multiboot
and send it as a multiboot ROM to my GBA and run it.
But when I compile as a usual rom it doesnt work.
when the master sends the logo it is little distorted behind the
o and (r).
I cant understand why!! When I send the ROM header I send from 0x2000000 when it was a multiboot ROM and then I changed it to 0x8000000 I think it something of that but I cant find out what!
Any ideas anyone?

1.
Is the rom image const?

2.
Display the actual memory address of the ROM that you are sending on the screen or through debug so you can double check the location.

3.
I do believe the header in your file may be corrupted, do you use GBAFIX to fix the header? Try including a const header array into your program ans see if it works from that.

4.
It may be your send code. Do you check the reply from the slave units?

It was the header I started to read from 0x8000000 from a flash cart where I already have some games. That eas a bit stupid
