Fails to flash application on xmega384D3

[codemonkey1000]

I crated a config file for the xmega384D3 and modified the Makefile to have the correct boot loader address.
the makefile programs the boot loader to the chip and i can enter the boot loader using a button. When trying to flash the application following your example it fails to program. avrdude says ****failed repeatedly and the verify step at the end fails also. Any idea why this might happen?

Have you tried with an explicit erase (avrdude -e)?

Thanks for the reply. I did not try -e. I looked at another boot loader, Xmega boot loader, it didn't work either. I was worried a bit that i was running into AVR1008 with the D3 chip so i tried with a C3, same thing. Ended up being the "page erase" command being sent from avrdude (6.2) Will try it with xboot later today with the -D and with -e. I prefer your make file solution, easier to automate. Thx Eric

using -D to disable page erase worked. xboot does flash using xmega384d3. On Sun, Nov 5, 2017 at 2:47 PM, Eric Weaver <[email protected]> wrote:
