small bootloader for USB
PostPosted: Fri Apr 18, 2008 10:33 am     Reply with quote
Hi.

There is any small bootloader (like Tiny PIC) for use with USB devices?

I'm going to make some tests with 18F4550 in custom driver mode and i like to use bootloader, but a smaller one like tiny PIC bootloader.


I'm not sure, but tiny works only with COM ports and with 18F4550 in CDC mode. right?

I have never heard of any small USB bootloader. The only one I know about is Microchip USB bootloader which resides from 0x000 to 0x7FFh.
More can be found
