---------------------------------------------------------------------
The bootloader looks for byte in eeprom at address 0x3FF:
-if it is set to 0xF0 bootloader will look for a bin file on the sdcard named
firmware.bin and use it to flash the firmware then reset the byte to 0xFF so it
does this only once
-if it is set to 0xF0 bootloader will look for a bin file on the sdcard named
firmware.bin and use it to flash the firmware then reset the byte to 0xFF so it
does this only once
-otherwise no action is taken and bootloader works as a arduino bootloader except
some of the debugging functions are missing

Generate BIN file for firmware update:
To generate a bin file you need issue the following command on you apps elf executable:
avr-objcopy -I elf32-avr -O binary firmware.cpp.elf firmware.bin
avr-objcopy -I elf32-avr -O binary firmware.cpp.elf firmware.bin
this generates firmware.bin which can be put on the sd for flashing your firmware. You can find the elf
file in you apps build directory.
