Recently I happened to write a Bootloader for ATXmega128A1 and I used BOOTRST fuse to start from Boot Section and then with a simple logic it goes to Application Section.
I did it very good and after that I decided to focus on my application so I wrote back the fuse to it's previous state for starting from Application Section and program the base
application to Application Section . It was the time I faced to the problem :
When I reset the power source the device could not start from Application Section. Surprisingly when I decided to read fuses with the JTAGICE MKII programmer then the device
starts. I did not change any fuses and just with reading it the device starts.
Where is the problem ?
