Cannot Upload firmware to Arduino
January 19, 2014 11:34AM
Hi there,

When I plug in my Ramps 1.4 through usb the green LED 1 starts flashing straight away, even though I'm not uploading anything.
When I do try to upload it just never ends.

I'm guessing some sort of reset would work?!

I have tried holding the reset button but the problem still persists.

Help is much appreciated!
