My PICkit2 says it works, but the code is not embedded in the chip. I think the problem is with the size of the PIC32 memory. HIDbootloader goes near the front of memory. The high address is 4A20. StickOS goes higher up. StickOS gives me the warning when I try to download it. I have been able to load HIDbootloader, but have not been able to load the OS. At one point I think I got the OS loaded but in so doing it wiped out the bootloader. Of course this is all guess work.
