This repository contains a beta bootloader that implements the USB-DFU protocol for the kemove snowfox keyboard. (Or any LPC11U35/401) for tha matter.
The bootloader expect to be loaded at flash address 0x0000_0000. You can do this by putting the controller into ISP mode, and drag drop the firmware bin file onto the controller drive.
If you want to build custom firmware using this loader, please have your firmware expect to be loaded at 0x3000. Also do no use the first 512 bytes of RAM. It will be used for reset/interrupt vector table. The table will be copied to first 512 bytes of ram.
