[avr-chat] AVRdude programming XMega256A3

[Fergus Dixon]

Hi

We are looking for some help with the AVRDude programmer.

We have a device which seems to program OK with AVRDude, but when the firmware program starts (after AVRDude has finished), the EEPROM settings are always corrupted and the program cycles back to the start always trying to reprogram the EEPROM. We are using an Atmel ATXMega256A3 microcontroller, and we can send the firmware.hex file. Any help would be much appreciated. We based the design on the Boston Android Eval board.

Here is the batch file we are using to program the device (using AVRDude 5.10):

avrdude -p x256a3 -c avr911 -P COM2 -b 57600 -e -U flash:w:Cubetape.hex
