I wanted to use libcartreset for a small project. The project is ARM9-only (well, I have been a DS programmer for less than 24 hours so far), so I added the following code:
| Code: |
u32 deviceType = DEVICE_TYPE_SCSD;
if (cartSetMenuMode (deviceType)) // Prepare the Slot2 device for reset
passmeloopEnter (); // Enter PassMe loop.
|
I'm using libcartreset_nolibfat 0.72, and Chishm's new fatlib. ATM I only want the reset function working on my SCLite, that's why I'm hardcoding the deviceType.
Anyway, the program just hangs, it does not reset. Any hints? Maybe I *must* also program the ARM7 for the reset thing to work? Or DEVICE_TYPE_SCSD is not suitable for the SCLite? It seems that v 0.72 supports it, but I couldn't find a more proper defined type in the headers for libcartreset.
BTW: LoveLite's resetting works on my SCLite.
Thanks in advance.

Hey SukkoPera! Sorry to disappoint you but, yes, you have to use the ARM7 as well. Otherwise, the whole 'PassMe Loop' can't be done.

Thanks for the instant reply!
OK then, I'll try that. I just don't understand if libnds has an integrated IPC mechanism or if I should implement my own. And also, what exactly can be done only on the ARM7 and what only on the ARM9.
Anyway, do you confirm that DEVICE_TYPE_SCSD is OK for SCLite?

I can confirm that it works with SCLite.
As for the ARM7, just build upon the template.c. The template code will handle all the stuff it should.

Thanks, everything works great now. Thanks for your help!
Oh, and now I can confirm it works with SCLite, too :).

One more question: any chance of getting this to work on GBA?

I don't know if there's a "standard" cart reset library for the GBA or not, although having the users patch the homebrew game with Boot-O-Matic Advance will usually work. A+B+Start+Select reboots the game, L+R+Start+Select reboots the entire system, bringing the user back to their flash cart menu.

GBA should follow the same principal:
1) Reset the media device to bootmenu-mode.
2) Jump processor to 0x080000C0.
On the GBA it's even easier, as you don't have to do the PassMe loop that involves the ARM9.

Jumping to 0x08000000 or 0x080000C0 does not reset the stack pointer. A proper GBA reset has three steps, which should be done in code running in IWRAM or EWRAM: - Reset the media device
- RegisterRamReset(0xFC) to erase all registers
- Set entry point to ROM and SoftReset()

Yup, that's something I need to put in libcartreset next version. Hehe.
