My current bootloader is 1.0.0. I think this may be causing some issues.
What file should I use to update the bootloader using Flip? Where can I find the file?
Thanks!
The code on the 16u2 isn't the bootloader, it's USB-serial firmware.
It's in (install location)/hardware/arduino/avr/firmwares/Arduino-COMBINED-dfu-usbserial-atmega16u2-(name of board).hex
That said, that is almost never a cause of problems - if it passes the loopback test, the problem is generally something else.
Thanks for the reply! When I try to load that file using Flip I get an address is out of range error. See attached file.
Load "Arduino-usbserial-atmega16u2-Mega2560-Rev3.hex" from atmegaxxu2/arduino-usbserial . I don't think you can load the combined version which also has the DFU programmer using FLIP. The only way I have loaded the combined.hex is using an ISP programmer.
If you find a way, post it here. I tried loading the same as you several times and had the same error everytime.
Check this out. It works for me.
