A while ago I became interested in smaller projects and I decided to buy a few Sparkfun Pro Micro's. The first batch I received had a USB mini connector and worked great.
The second batch I received we're a new revision and had a USB micro connector, no biggie. The thing that struck me though was that my sketch wouldn't boot immediately (only after 8 seconds). I found some reference to it and I didn't like it ..
Now the third batch has come in and these seem to have a new bootloader yet again. The Sparkfun website also has a document called "firmware note" that talks a little out it. Basically my sketches on these boards are loaded immediately again.
My question: I have a few of these boards laying around the house that have the 8 second delay feature. Is there any way for me to prep these boards with the newest bootloader? Now that the new batch doesn't have this feature I am really bothered by it.
I have a USB Serial Light adapter, a Tiny Programmer and a Arduino Duemilanove and the Pro Micro's have USB to them as well.
Hope you can help thanks
