Hello 

I want to program fusebytes for ATxmega128D3 using atprogram.exe tool and Atmelice programmer.

I see that fusebyte 0 ,fusebyte 3 are reserved in manual for that IC.

Is it correct if I wrote in cmd line seq for 6 fusebytes like below:

(I need to set up only 4 fuse bytes(AS7 has only 4) but in that tool looks must by 6 fusebytes (fuse0:FF and fuse3:FF) because without them fuse seqence after program was wrong.

Below my seq:

.\atmelICE\atbackend\atprogram.exe -t atmelice -i pdi -d ATXmega128D3 write -fs --values FF00FFFFF3EB --verify

 

Now when I run in AS7 it looks good but I m worried if I could set up FF to reserved fuse0 and fuse3.Is it safe or not.(I read that normally fresh IC also have FF setup from factory)

In AS7 only 4 fuse are visible like below.

If there anyone has  similar problem how to automate programmnig of fuse in that IC.

 

Below read fuse after atprogram run.

If you include the fuse setting in the program, there is no hassle.

 

#include <avr/io.h>

FUSES = {
    .FUSEBYTE1 = FUSE_FUSEBYTE1_DEFAULT,
    .FUSEBYTE2 = FUSE_FUSEBYTE2_DEFAULT,
    .FUSEBYTE4 = FUSE_FUSEBYTE4_DEFAULT,
    .FUSEBYTE5 = FUSE_FUSEBYTE5_DEFAULT,
};

int main(void){
    while (1){
    }
}

This is an example of atprogram that writes a flash and a fuse at the same time.

 

atprogram -f -t atmelice -i PDI -d atxmega128D3 program --flash --fuses --verify --file GccApplication1.elf

Hi KabaSan

It works now correctly. I used like you wrote elf file and then atprogram.

Thanks a lot!
