Jubatian created a new bootloader for Uzebox.

Use your ISP

Write the bootloader

To use these features you will need the new v5+ bootloader.

Once you have it you can use these commands to flash them to your Uzebox (assuming you have a USB Tiny ISP... if not just change the -c value to whatever you have.)

sudo avrdude -V -p m644 -P usb -c usbtiny -B 1 -U flash:w:Bootloader5_10.hex

Write the fuses

Since you are writing the bootloader and have an ISP handy you may as well make sure that your fuses are correct:

sudo avrdude -V -p m644 -P usb -c usbtiny -B 1 -U lfuse:w:0xD7:m -U hfuse:w:0xD2:m -U efuse:w:0xFF:m
