For problems with Gamebuino itself, NOT your project
by albertinjo » Fri May 16, 2014 3:59 pm
The indiegogo update says that the last boot-loader bug was fixed. I shall try the new version soon. (I dont have much time now)
Thank you for the help in making this work on an unofficial hardware.

Yep, now the bootloader should be okay with any SD card. The latest version is on Github (not updated on the wiki yet).
There is two hex files you can choose from:
- gamebuino_boot_simple.hex = just the bootloader (as before)
- gamebuino_boot.hex = bootloader + settings.hex: this way once the bootloader is flashed it will directly allow you to change the settings which are stored in the flash memory (like contrast)

It's normal that you don't see any differences with the last loader sketch has the fixes are in the bootloader itself. Sorry, but you'll have to flash it again if you want to solve your problem! If you're too lazy, you can buy an USBasp on ebay from china from something about 3€, so you won't have to mess with the Arduino as ISP setup.

Recently I tried the new bootloader. Now I can load not only simple games but alse more complicated ones. The problem is that I cant invoke the loader sketch after the game is loaded to flash memory from sd card.
Basically I flash loader.ino program to my arduino (via my PC), the loader sketch loads a game from the SD card, but I cant invoke the loader sketch to load another game. When I press C button on startup it just says "loading" and restarts.

Don't you need LOADER.HEX on the SD Card?

Yes I have copied the LOADER.hex to my SD card.
Rodot, in your last post you said:
There is two hex files you can choose from:
- gamebuino_boot_simple.hex = just the bootloader (as before)
- gamebuino_boot.hex = bootloader + settings.hex: this way once the bootloader is flashed it will directly allow you to change the settings which are stored in the flash memory (like contrast)
Can you explain me how to choose which bootloader I want to program into my arduino, when I was burning the bootloader I just followed the instructions, which say:
1) Copy the contents of this folder into a new folder in C:\arduino-1.0.5\hardware\arduino\bootloaders\gamebuino_boot
So I just copied both boot.hex files along with other files in the folder and burned the bootloader.

When you burn the bootloader using the arduino IDE it uses the file name provided in boards.txt, so by default it will burn gamebuino_boot.hex. You should use this one because it also includes "settings.hex", this way it will start up right after you burn the bootloader and allows you to set the contrast and check that the Gamebuino works fine.

The bootloader works really weird on my aruino, the loader sketch works fine, I can read files from my sd card with the SDfat library. Only problem is that I cant invoke the loader sketch while holding the C button on startup??
