BlueARP DM unit. Bootloader, firmware update, interface sneak preview

Sorry for shaky phone video, I filmed it 7 a.m. before going to work.
Yesterday I made a bootloader for bluearp unit. Basically it is a thing that allows customers to update device firmware via USB stick of SD Card, in my case.
It works like this - you place a file to SD Card, power on the device holding some button and follow the instructions, nothing special. But I made it in one day which is good since I never did it before.
One more small step towards making BlueARP unit available for customers ).

A great and talented man. He should get a lot of money and work for famous musicians. Has talent that should be developed. I am convinced that if he had the right funds, he would succeed in his field.

Yes, these are old school clicky buttons. Rubber pads are more modern, but these have some old school charm, like early computer keyboards )
