Edit: prebuilt binaries now available at github!
I wrote a a bootloader for the Stellaris Launchpad (and other Stellaris boards/chips) that acts as a USB mass storage device.
It's inspired by the bootloader found on some NXP LPC microcontrollers.
Just plug in your board while holding SW2, it shows up as a tiny external drive, copy your firmware.bin to it and *bam!* your board has new firmware!
You can also download the current firmware from the drive.
It takes up 16kB of flash memory.
Please test it and report any issues!
Usage instructions at github.
