Re: Help with bootloader on Gemma v2
You're trying to repair the bootloader on a Gemma? You need to connect an Arduino Uno and upload the bootloader repair sketch:

I'm not trying to repair it but load the example file. It comes up with an error saying the boot-loader file doesn't exist and i used the easy instillation on your webpage. thanks for the help.

Re: Help with bootloader on Gemma v2
Loading the example file is not the same as loading a bootloader. You do not use the load bootloader menu item.
Load the example in the Arduino IDE and click the upload button.
The only other thing you have is to make sure that the USBtiny programmer is selected

You have the press reset on the Gemma right before the upload. The red LED should be pulsing when the upload begins. It will pulse for 10 seconds after you press reset.

What kind of operating system are you running on? Windows? Mac?
