It sounds like they hooked up the board to a PC, sent some characters to it, and watched what happened. You haven't been talking to the right people at SparkFun. They manufactured the board and the 877A surely didn't come from MicroChip with a bootloader. I'd ask them to talk with the original designer of the board to get the scoop on the bootloader (which one and which version) preloaded on the chip.bigsimmo wrote:Oddly enough, tech support at SparkFun said they had to send a character at the board to be able to get a response. They didn't provide any more detail than that.
