Hi all!

I searched the Forum and I'm wondering that there really seems to be no USART Bootloader for the UC3A0/1 device family.
I have two custom boards, running very fine, and I'm looking for a way to update the FLASH from PC Software. But I have only a RS485 connection. Comming from the good old ATMega I didn't spend time in advance on this little detail :-(
Now, the boards are ready for production and I just want to finalize my job by implementing a bootloader and oops!!

regards,
Tom

yes, good idea to use xmodem

for the flash routines have a look on ASF's flashc driver,
the USB bootloader source might be a good reference, too.
