Uploading NuttX to the Due Using Bossa:

But, fortunately, since you already installed Arduino, you already have
BOSSA installed. In my installation, it is here:
C:\Program Files (x86)\Arduino\arduino-1.5.2\hardware\tools\bossac.exe
C:\Program Files (x86)\Arduino\arduino-1.5.2\hardware\tools\bossac.exe
Where is some sample output from a Windows CMD.exe shell. NOTE that my
Arduino programming port shows up as COM26. It may be different on your
system.
General Procedure
-----------------
To enter boot mode, set the baud to 1200 and send anything to the
programming port:
1) Erase the FLASH and put the Due in bootloader mode
2) Write the file to FLASH
3) Configure to boot from FLASH
4) Reset the DUE
C:\Program Files (x86)\Arduino\arduino-1.5.2\hardware\tools>mode com26:1200,n,8,1
Erase FLASH and Put the Due in Bootloader Mode
----------------------------------------------
This is accomplished by simply configuring the programming port in 1200
baud and sending something on the programming port. Here is some sample
output from a Windows CMD.exe shell. NOTE that my Arduino programming
port shows up as COM26. It may be different on yoursystem.

Erasing, writing, and verifying FLASH with bossac:

In a Cygwin BaSH shell:

This error means that there is code running on the Due already so the
bootloader cannot connect. Pressing reset and trying again

a) Write code to FLASH don't change boot mode and don't reset. This lets
you examine the FLASH contents that you just loaded while the bootloader
is still active.
