Dear Friends,
I have a weird issue to program my ATxmega64A3 with AVR Studio 5.0
When I using AVR Studio 4 and JTAGICE mkII to program the uC I have no problem. I could read and write Fuses and Flash easily, and when I repeat this task still there is no issue
But when I try to do the same task with AVR Studio 5, until I do not write anything to the mcu I could read it. but when I try to erase or program the fuses or any other "Writing" task, the programmer return error, and after that the mcu no work any longer !
I try it on lots of mcu and all of them stop working. I guess the AVR Studio or programmer corrupt the Fuses "even when I just try to erase device" and because of that JTAG become disabled.
My programmer do not support PDI and I couldn't test it via PDI yet. I am going to buy a PDI supported programmer as soon as possible to confirm that is Fuses issue or whole mcu damaged.
I also should tell you I did not have the problem at first, every things worked fine when I just use the system just for run time debugging. But after I decided to change one of the fuses the problem just has been raised. and after that the problem still remain even when I change the mcu several times !
I try to uninstall the AVR Studio 5 and reinstall it again, but nothing happened 
Have anyone any Idea? Is there any setting in AVR Studio 5 which told it to set the fuses before erase?
By the way, in the mean while until I found the issue, I decide to write my program in AVR Studio 5 but program it via AVR Studio 4. But AVR Studio 5 generate .elf file and studio 4 expect .a90
How could I force AVR Studio 5 to generate any bin file which is supportable by AVR Studio 4 ? |

| First, I would switch to Studio 6 beta, as there are lots of bugfixes. Also, in the project properties in Studio 5, you can choose elf,hex etc... In Studio 6, all these files are created. |

| I wish I could switch to atmel studio 6. But unfortunately, my jtagice mkII programmer is a clone one by mcuzone and they didn't have driver for studio 5.1 and studio 6 yet. |
