When trying to upload to my Mega r2, it simply times out during uploading.
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
I tried burning the bootloader, but that also gave an error.
Error while burning bootloader.
avrdude: usbdev_open(): did not find any USB device "usb"
I can see the arduino in my Devices and Printers in control panel, so I don't think the board is burnt. The power light also is on. Any ideas?
dmesg
(Linux), or similar on other platforms. On Linux/iOS you want to double check device permission settings.
