Anyone have any favorite bootloaders for the 18F4610? I've looked at the TinyBootloader and the TheByteFactory CodeLoader. I'm kinda leading towards the CodeLoader code, which is written in CCS C. Though considerably larger, you just send the hex files to it and they are decoded in the bootloader instead of in the host program. However, the CodeLoader code seems to make calls of several functions that are not included in the package of files. I'm moving it over to Microchip C, so perhaps those function calls are defined in CCS C. Any comments? THANKS!
