ok here is my problem
i have a simple gba program compiled in Multiboot mode
i load it on gba using a hand made PC-GBA serial cable
on my flash card i use FrotzNet gba remote console
when the multiboot rom is compiled using devkitadvance r5beta3 (windows version) it works
when i compil it under linux using devkitadvance r4 it doesnt work
does anybody has had a similar problem in the past ?
thx a lot

How is it not working? Are you getting some compiler/linker errors, or does everything build fine but it just doesn't do anything on the GBA?

no compiler/linker error
program load normally using the multiboot cable, the gba loader branch to 0x02000000 and black screen and nothing runs

Isolate the problem: Is it the link cable, or is it the program you sent? Does the program work in VisualBoyAdvance?

ok i investigate more the problem
if i compile using devkit r5 on windows and look at the generated map file the rom is a valid multiboot rom (i.e. starting at 0x02000000 etc)
if i compile using devkit r4 on linux and look at the generated map file
the rom is located at 0x08000000 :/ (so its not a multiboot one but __gab_multiboot is defined at the beginnning of my main.c)
and the rom doest not work in VBoy Advance
:/

In all fairness you are comparing devkitadv <b>r4</b> for linux with devkitadv <b>r5 beta</b> for Windows. Can't that be the issue? What happens if you use devkitadv r4 for Windows?
