Use devkitARM found at http://sourceforge.net/projects/devkitpro

the buildscripts are available there should you wish/need to compile
from source.

There are some basic examples in CVS with makefiles that should get you
started :)

Dave

this makefile should help.

Hello all,

       I'd like to start with Gameboy development (GBA)
with GCC. I looked around a little on the net and I am
a bit confused: one binary distro uses the crtls, the
other one doesn't.

Can someone tell me where I can get a decent linker
script/libraries ? I've compiled GCC-3.4.3 and
binutils-2.15.94.0.2 and newlib-1.13.0 for the arm-elf
target (following the crossgcc script).

How do I convert my compiled *.elf into a *.gba ??

Kind regards,

Jan

Hi,

I purchased a 128Mbit ProCard for gameboy advance from shop.01media.com
  and am unable to get it work on a WinXP laptop and Win2K PC with
latest drivers. Client software supplied is a utility called GameFuzzy.
It connects to the card, but all writes end with the popup message
"Write game fail!" When I recycle power, the boot screen displays some
pink garbage where the "Nintendo" string should appear, and it freezes.

This is with a known good .gba file. Have tried on a GBA SP as well as
classic.

Returned this to the retailer at my cost (12euros to ship) and received
an exchange card (I hope) which has exactly the same symptoms.

Are there any known issues with this card/drivers or the retail store ?


regards
Hari

Unfortunately it is not free. SanDisk commercializes the SD software
tool Kit (SDDK) for some thousands of dollars.
I do not know why they do not give it for free. The money they get
selling the kits are peanuts for them. They would easily get the
money back by selling more SD cards.

Hello,

     Has anyone some code available to run the gdb
remote protocol on the GBA itself? I already
understood there is no JTAG interface available (what
a pity :-( ) so I'd like to use the GDB remote
protocol as a replacement.

Kind regards,

Jan

Don't know yet if this is free, but Sandisk website has a document
describing a reference source code library  with low level drivers as
well as a FAT16 file system interface.

check libogc at devkitpro.sf.net .... it has sd-card support, and fat
aswell.... and the gamecubes exi-bus is pretty much the same as
spi too, so you probably can adapt it easily.

Hello,

Does anybody have any information regarding a 'free' library for file
access and management on SD/MMC cards (FAT16/FAT32)? I intend to use
the SPI interface to access the cards.
C or C++ languages are OK.

Thanks in advance,

As far as I know it is not possible to use both processors.  My
understanding is that the GBA comes up either in native GBA or in GBC
compatibility mode, as determined by the micro-switch, and the two
modes are mutually exclusive.

So if I understand it correctly, it is impossible to
use the ARM controller and the Z80 controller at the
same time in a kind of multiprocessing mode ?

Hello,

I am designing a cartridge for the GBA and would like to add a small
sized flash card to it, to use as mass storage. I have tried to get
the specifications for SD cards and other types but it seems that the
manufacturers do not disclose them.
Does anyone have any information about this?

I would appreciate any help.

thanks,
Vital

Salam Farhad,

I looked at your website and the eBay auction for your GameBoy CPLD
product.  Good work!  However, I believe you will need a mechanical
redesign to get your board to run on a GBA (or GBA SP).  A few years
ago I designed a board to run on a GBC (see
www.databoy.netfirms.com).  When GBA came out I discovered that my
board would not run it, even though GBA is backwards compatible with
GBC.  As someone else already commented, GBA has a micro-switch that
detectes which type of cartridge is inserted (GBC or GBA).  After
some experimentation I figured out how to modify the shape of my
board to activate the switch in the GBA to place it in the GBC
compatibility mode.  My modified board will now run on a GBC, GBA, or
GBA SP.  I would be glad to share the details with you.  Please
contact me offline if you are interested.
P.S. The photos you have on eBay show your board plugged into a GBA.
I think this is misleading because I believe your current board will
not run on a GBA.

Regards,
Yosuf Taraki

The GBA cart is notched on the side and the GBC is not. This operates
a switch inside the GBA to turn on 5V (and makes other adjustments
such as switching on a different CPU) if a GBC cart is inserted. GBC
carts work in the GBA by design, not by chance!

Hi,
I have a question about the use of GBC cartridges inside a GBA unit. I
know that manyof them work without any problem and I wonder if that is
a general case?

GBA is 3.3V and does not have any 5V outputs as far as I can tell. And
most if not all the GBC cartridges are 5V only, is there a trick?

The reasone for this is that I want to test my GBC cartridge
(http://www.abdolian.com/gameboy) inside my GBA.

Any help is highly appreciated,

Best regards,
/Farhad

...does anybody know where I can get it?

Thanks,
   - c5.

Update: I have found the solution myself.

I had an org 2000000h instruction in the header of my program.

Removing that line solved all my problems - I have now my picture on
the screen.

Sorry for the stupid mistake...

Miklos

Hello all,

I have a question about memory structure in the GBA.

I have the following code (taken from a GBA assembler tutorial).

The code should display a picture on the screen

------------------------------------------
main:
         mov r0, #0x4000000
         mov r1, #0x400
         add r1, r1, #3
         strh r1, [r0]
         mov r0, #0x6000000
         ldr r1, =pic       @ my question refers to this line here!
         mov r2, #0x960
loop1:
         ldmia r1!, { r3,r4,r5,r6,r7,r8,r9,r10 }
         stmia r0!, { r3,r4,r5,r6,r7,r8,r9,r10 }
         subs r2, r2, #1
         bne loop1

infin:
         b infin
.ltorg

pic:

     DCW 0x4A31,0x4E52,0x4A31,0x4E52,0x4E52,0x4E52,0x4E53,0x4A32
     DCW 0x4A31,0x4631,0x4631,0x4A31,0x4631,0x4631,0x4610,0x4611
     DCW 0x4631,0x4A52,0x4A52,0x4A52,0x4E72,0x4A52,0x4A31,0x4A31
and lots more of DCW...

------------------------------------

When I use the code with no$GBA it assembles and runs fine.  The
result should be a picture shown on the GBA screen.

However the program runs, but the screen remains black.

Debugging the program I find, that the line
   ldr r1, =pic
does not point to the picture data.

My code is in the 8000000 adress region, so the pic: data is at about
  80000FC. However when I stop the debugger right after the mentioned
instruction, I see, thet r1 contains  20000FC. That adress (20000FC)
is according to the debugger filled with lots of zeroes, therefore no
surprise that my screen remains black.

What am I doing wrong here? Why does the above mentioned instruction
not contain the proper adress for my data?

I am sorry for the newbie question - but I am stuck here. Any help
would be really welcome!

Thank you all,

Miklos

Google gba assembler tutorial and you will get many useful hits. Good luck.

I drew and scanned 2 characters with simple moving.
I don't know how to write the event code that control these

Thank you. I already found it. It looks great, however it also looks
fairly complex for me (being at the very early learning stages). I was
hoping to find a couple of examples which are much shorter (and
therefore easier to understand).

I can't seem to find nedcmake.exe and nedcenc.exe anywhere, and the
online dotcode generator link now leads to a porn site.

Is there some place I can download these tools, or are there alternate
forms of converting VPK files to raw data?

Thanks for your help, and if I'm just being blind, I appologize. :P
