how to program the SYSCFG0 fuse on the avr128da28 ??

[manes6969]

Hi ,
How can I program the syscfg0 fuse on the avr128da28 using my pickit5 on avrdude ?
Any help welcome.
Regards,

Did you try the docs?

if not you can try avrdude -c pickit5_updi -p avr128da28 -U syscfg0:w:0xff:m, where 0xff is the fuse value.

Hi Mcudude ,

As far as I could see , it was not in the docs using version 8.
I tried your answer and it works like a charm. Thanks a lot !
You've made my day with this.

Grat to hear you got it working. There is also an interactive "fuse calculator" built into Avrdude.

You can invoke it using the -t flag:

$ avrdude -c pickit5_updi -pavr128da28 -t

avrdude> quit

Avrdude done.  Thank you.

Terminal mode (-t) has lots of different features. You can view them by typing help.
