[SOLVED] Firmware Update through VUSB

Post by mschumann » Fri Jun 05, 2009 8:13 pm

Is it possible to extend the HID-DATA Example in a way that one can update the firmware through this USB Port?

I saw some applications where usb routines write to flash. I don't understand how this can be done while a program is running in exactly that flash memory.

Any help, tip and/or explanation is very welcome! Thanks in advance.

That's exactly what you want.

Thanks a lot. No single second I regret having decided to use the atmel family for my handicraft work.
