This Ecxel file does not work with OOo. I have made a little online
calculator for the Xmega USART

Please send me a message if you find any kind of problem.


Meanwhile I made some tests with a patched avrdude 5.6 (usb_libusb.c)
and ATxmega128A1. Chip Erase, reading and writing Flash works fine.

Reading and writing fuses does'nt work. I try it with -U fuse0:r:-:i

Reading fuse bytes using fuse0, fuse1 ... runs without error, but it
always reads 0xFF. Writing Fuses fails.

Reading and writing Eeprom seems to work

I can only test avrdude 5.6 and ATmega128A1, so that's all for now

Markus
