Using the mbed bootloader on the LPC1768 from local tools

Hi. I've been teaching a class that uses the LPC1768 and uses mbed (version 2, I believe). At one point, there were instructions for building a toolchain on my own machine. I have a toolchain which seems to be properly building the application (using gcc), but I'd really like for my students to be able to take advantage of the built-in bootloader that comes with the LPC1768 (You can't get more convenient than copying a .bin file to a mass storage device, and then restarting).

Has anyone accomplished this? Anyone know where I can find information on doing this?

So far, I've found an odd reference or two which suggests I need to calculate a CRC over the first few vectors (done that). But it's still not launching my custom app. Any help would be appreciated (particularly if it involves references to the startup or linker files you're using).

Thanks!
