I have a mega 2560 r3 that i had been playing around on for a little bit. I had tried to use a USBtinyisp to flash a midi firmware software onto it,but it just ended up messing up my board.
The weird thing is that is shows up in device manager as the 'arduino mega 2560(com3)' so i figured it would still be ok. The IDE detects it as well. When i upload sketches, it will look like its sending it over but it doesnt. Trying to reinstall the bootloader from the IDE doesn't work either when i have it hooked up through usbtinyisp.(hangs)
I downloaded 'flip' in hopes of getting it to flash but it says 'could not open usb device'
trying to flash the midi firmware on avrdude and i get this: usbdev_open(): did not find any USB device
Figured that i got the right device and that usbtinyisp would be able to reflash it back to normal.Not sure if it needs to be in DFU mode or what to get it to flash over.
Does anyone have any idea what .hex file i would need to flash over and the steps to fix this? Maybe the usbtinyisp isn't capable of flashing on the 2560. The ebay person said it would that i got it from.Idk.thanks
