Hello :-)

I am developing a board for 3D printer RepRap using LPC1768. I have 2 questions:

1. I am trying to use the USB bootloader from CodeRed examples here:
http://support.code-red-tech.com/CodeRedWiki/RDB1768cmsisExampleProjects

The bootloader is working as USB Mass Storage and I can see it on PC,
I can delete the firmware.bin file and copy to there my firmware.bin
file. The problem is that looks like the bootloader do not write on
flash memory my firmware.

I wrote a blink LED using interrupts, to test the bootloader. I am
remapping the interrupt vector table to the 64kbytes flash. The code
works as standalone and I can debug it correctly. Does anyone used
this bootloader? is there any code for a bootloader that works?

2. I would like to have a cheap USB bluetooth pen, however I don't
know if there is some Open Source code out there for it. Mbed have it
but the code is not Open Source.
