I created a xboo multiboot cable and every time I want to send something to the gba I get this one:
C:\DOKUME~1\Philipp\EIGENE~1\DOWNLO~1>xboo 378 tod
No$gba boot copyright 9/2001 martin korth
Detected delay time: 038B
- Requesting Burst Boot
- Sending Reset and Requesting Normal Boot
- Sending Header Data
- Sending Main Data Block

Does anyone now what could be wrong ?
Thx

Are you sure you got a multiboot rom?
#3003 - Bri - Sun Feb 16, 2003 11:27 am
Yes I think so.
I tried it with several roms but I always get this error.
#3004 - Jakerrzero - Sun Feb 16, 2003 11:35 am
i am having exactly the same problem right now! im pretty sure your rom is probably just not multi boot. I downloaded a multiboot rom from somewhere and it worked. Now i am just trying to figure out how to make my own roms multiboot. i use the vc++ integration tool, i was told i just had to use this line of code and the linker script would take care of making it multiboot:
const int __gba_multiboot = 0;
but i haven't had any luck with that...
anyone that has any more information on this
im sure bri and I would both really apreciate it!!!
thanks!!!

it's ok :)
i sent that file to you.
hope it works!
if you find out how to make your own roms bootable please let me know

Tried it with the rom I got from you and now I get this :(

but then it works for me.
i made a .bat file with these arguments:
xboo.com /378 /n test.gba
the /n is to disable burst boot cuz i made my cable the simplest way.

Hmm... the /n parameter doesn't seem to work with my version of xboo.
Maybe you have a newer one ?
#3010 - ampz - Sun Feb 16, 2003 12:02 pm
Bri: you are using a old version of XBOO, it does not support fast computers.
#3013 - Bri - Sun Feb 16, 2003 12:09 pm
where do I get the new one ?
I currently try it on a P4/2,66Ghz with winxp, but it also didn't work on a P1/166Mhz with win98.

#3016 - Jakerrzero - Sun Feb 16, 2003 12:14 pm
ampz do you have any idea why when i code the lines:
#define MULTIBOOT int __gba_multiboot;
MULTIBOOT
in my globals area in my code, i still get the error:
Bad response (probably incorrect header)
#3017 - Bri - Sun Feb 16, 2003 12:19 pm
thx a lot .... now it works :)
#3018 - Jakerrzero - Sun Feb 16, 2003 12:29 pm
right on :)
did you get your own roms booting? or just the test i sent you?
if you got your own booting can you explain how you did it?
thanks
#3019 - Bri - Sun Feb 16, 2003 12:38 pm
I haven't tried to program a own rom but I tried the Firedemo (MattDemo3) from http://axio.ms/projects/GBA/ but I get the Bad checksum error.
Shouldn't it work with a multiboot cable ?
#3020 - ampz - Sun Feb 16, 2003 1:01 pm
Jakerrzero: dunno, I don't use that kind of defines.
Are you all using the correct header? The [N] logo is ok? the CRC is correct?
The MB part of the header should look something like this:
| Code: |
@ Software Version No (80000BCh)
.byte 0x00
@ Complement Check (80000BDh)
.byte 0x88
@ Check Sum (80000BEh)
.byte 0x00,0x00
@ Multiboot entrypoint (0xC0)
b rom_header_end
@ Boot mode (0xC4)
.byte 0x00
@ Slave ID (0xC5)
.byte 0x00
@ 20000C6h..20000DFh - Not used
.byte 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00
.byte 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00
.byte 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00
@ Joybus entrypoint (0xE0)
b rom_header_end |
Make sure that the CRC is calculated correctly, and the N logo is ok.
Also, have you set your compiler to 0x02000000 instead of 0x08000000 ?
