Has anyone had success with building one of these? More specifically flashing the AVR? http://spritesmods.com/?art=gbamidi
I have a programmer and have been trying to get it to work with no luck. His readme text says to use the makefile, but I'm getting errors when I try that. prolly cause I'm not using WinAVR like he is (I'm using mac). I've been just using avrdude to set the fuses and upload the .hex file provided. I still can't get any mutiboot response out of it though. I'm actually a beginner, so I don't know anything past what I've been able to piece together from tutorials/forums/help texts. If anyone with actual knowledge and experience with this could tell me if I'm doing things right/wrong I would be very grateful. Here's what I've been executing.
$ avrdude -c usbtiny -p m168 -u -U flash:w:gbamidi.hex -U lock:w:0x2f:m -U hfuse:w:0xdF:m -U lfuse:w:0xFf:m -U efuse:w:0x00:m I found those fuse bit values inside his makefile.
One thing that struck me as odd is that when I use terminal mode in avrdude and 'dump flash 0 16800' the lines 0000 all the way through 3800 are all 'ff', which if I'm not mistaken, that means blank. Though it might have something to do with something else I saw in the makefile. near the top under where he declares the MCU, it says 'BOOTLOADER_ADDRESS=0x3800'. Like I said I'm a beginner so I don't know much about any of this stuff. All I wanted was a MIDIboy Advance
