I'm really at my wits end. For a couple of hours I have been programming a custom board that uses everything as on the Arduino Leonardo. A few hours ago I am not able to upload anymore.
I get the following error:
avrdude: error: buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device?
I've tried everything from re-installing the IDE, re-installing the board in Device Manager, changing the COM Port. I really just don't know anymore.
Here is some more data that might be relevant or useful:
Using Port :\\.\COM6 Using Programmer : avr109 Overriding Baud Rate : 57600 AVR Part : ATmega32U4 Chip Erase delay : 9000 us PAGEL : PD7 BS2 : PA0 RESET disposition : dedicated RETRY pulse : SCK serial program mode : yes parallel program mode : yes Timeout : 200 StabDelay : 100 CmdexeDelay : 25 SyncLoops : 32 ByteDelay : 0 PollIndex : 3 PollValue : 0x53
[EDIT] I've now checked the battery (yes with a multimeter), it is fully charged, as it charges when the USB is connected. I've also tried a different computer, along with a different USB cable.
